Power cord for the United Kingdom

When using the PEL-2002/2004 in the United Kingdom, make sure the power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow: Earth

Blue: Neutral

As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol or coloured

Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the supplier.

This cable/appliance should be protected by a suitably rated and approved

HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm2 should be protected by a

3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

Channel Number

Description

The channel number for a module load is determined by which slot it occupies on the mainframe chassis. There can be 1 or 2 channels per slot, depending on the load module type.

The PEL2002 has two slots; The PEL-2004 has 4 slots. Channel 1 is the farthest away from the main display panel and channel 8 (PEL2004) or channel

4 (PEL2002) is the closest to the main display panel.

Below the PEL-2004 has all 4 slots occupied with the PEL-2020, 2030, 2040 & 2041series load modules (LM), respectively. The PEL-2020 & 2030 have 2 channels per load module, the PEL-2040 &

2041 have only 1. So the channel determination is:

LM1: CH1,CH2; LM2: CH3,CH4; LM3: CH5; LM4:

CH6.

Load Connections

Precautions and Procedures

Intoduction

The PEL-2000 load generator supports a number of different load configurations for flexible operation.

 Single DUT, single load

 Single DUT, parallel load

 Multiple DUTs, multiple loads

 Multiple DUTs, multiple mainframe loads

 Single DUT, parallel mainframes

 DC loads

 Low voltage connections

The PEL-2000 also supports a number of different control methods and interfaces. The connections used are described here:

 Frame link

 Channel control

 Go/NoGo

Wire Gauge considerations

Before connecting the PEL-2000, wire gauge must be taken into account. Load wires must be large enough to resist overheating when a short-circuit condition occurs as well as maintain a good regulation. The size, polarity and length of a wire are all factors in determining if a wire will withstand short circuiting.

43

PEL-2000 Series User Manual

Wire Selection

Wires that are selected must be large enough to withstand a short circuit and limit voltage drops to no more than 2V per wire. Use the table below to help make a suitable selection.

Inductance

Considerations

When using the PEL-2000 load generator, voltage drop and voltage generated due to load line inductance and current change must be taken into account. Extreme changes in voltage may exceed the minimum or maximum voltage limits.

Exceeding the maximum voltage limit may damage the PEL-2000.

To determine the voltage generated, the following equation can be used.

E = L x (∆ I / ∆ T)

E= voltage generated

L=load line inductance

∆ I= change of current (A)

∆ T= time (us)

Load line inductance (L) can be approximated as

1uH per 1 meter of wire. (∆ I / ∆ T) is the slew rate in A/us.

44

The diagram above shows how changes in current can affect voltage.

Limiting Load line inductance

Load line inductance can be reduced by ensuring load wires are as short as possible and by twisting positive and negative load wires together. Current change can be limited by limiting the slew rate when switching.

“Twisted pair” will be shown on any connection diagram where the load wires should be twisted together.

45

PEL-2000 Series User Manual

Load module considerations

The PEL-2000 supports single and dual channel load modules.

Single channel load modules have one bank of negative terminals and one bank of positive terminals. Each terminal pair has a 40A capacity.

For higher loads, each terminal can be wired in parallel to increase capacity.

Dual channel load modules have one bank of positive and negative terminals for each channel.

80V DC 80V DC

L R

Follow the procedure below for all load connections.

Ensure that power is off from the load generator and the DUT before making any connections.

1. Carefully lift the terminal covers.

2. Connect the positive (+) terminal on the load module to the high potential output of the

DUT.

3. Connect the negative (-) load terminal to the low potential output of the DUT.

46

4. Close the terminal cover securely. Ensure the wires are secured properly and that the wires are not exposed when the cover is in place.

WARNING

Ensure that the wires are tied or twisted together to prevent noise and inductance.

CAUTION

Ensure the polarity is correct before proceeding with any connections. Using the wrong polarity could result in reverse voltage damage.

DUT

Ensure the input voltage doesn’t exceed specifications.

Exceeding the voltage specifications could result in damage to the instrument.

47

PEL-2000 Series User Manual

Remote (Sense) Connection

Background

The electronic load modules have two voltage sense contacts: Vsense L(black), Vsense R(red).

Voltage sense can be used to help compensate for long cable length. The longer the cable, the higher the potential resistance and inductance, therefore a short cable is best. Twisting the cable can help reduce induced inductance and using the Vsense terminals compensates the voltage drop seen across the load leads, especially leads with higher resistance. This is useful when used in CV or CR mode.

WARNING

VsenseR (red) must have a higher (+) potential than

VsenseL (black).

Connection

The diagram below shows how a DUT can be connected using voltage sense. Note that the sense wires are also twisted pairs.

Note

Input

The wire gauge for the sense wires should be no smaller than 16 gauge.

The voltage sense terminals must use a wire gauge of 16 to 14.

48

Remote Sense

Terminal connection

The voltage sense terminals use a screw-less clamp connector. The clamp must be opened prior to inserting a wire. Use a small screwdriver to push the clamp release mechanism. Insert both wires then release the clamp mechanism.

Single Load Connections

Dual Channel

Load Module

Connection

A dual channel load module can be used to sink two loads concurrently.

Single Channel

Load Module

Connection

On a single channel load module, the left terminals are both negative (-), whilst the right terminals are both positive (+). Note this also applies to the voltage sense terminals.

CAUTION

For loads exceeding 40A, both positive and both negative terminals must be used in parallel.

50

DC Connection

For purely DC operation, a resistor and capacitor can be connected in parallel to the electronic load to reduce oscillation. The capacitor and resistor values are dependent on the load settings. Ensure the capacitor ripple current is within allowable limits.

Low Voltage

Connection

Using the load generator with low voltage loads is generally limited to over 1 volt (load module dependent). In order to support low voltage loads, an auxiliary power supply is needed to boost the voltage to a range suitable for the load generator.

Precautions:

 Take into account the combined power of the load and auxiliary power supply.

 Make sure the auxiliary power supply is able to provide enough current.

 Take into account any noise or irregularities from the auxiliary supply.

The diagram below shows a typical connection.

WARNING

Using an auxiliary power supply may induce reverse current. The PEL-2000 series has reverse voltage protection. For details see the protection section on page 79.

51

PEL-2000 Series User Manual

Parallel Load Connections

Parallel load modules

When the power output of a DUT exceeds the power rating of a channel or load module, the channel terminals, load modules or mainframes can be used in parallel to dissipate more power when used in CC mode. Each channel will sink the amount of current specified. The total power sunk is the sum of all channels/modules. The amount of power can vary from each channel. For example if

CH1 is 25A and CH2 is 20A, then the total current sunk is 45A. Parallel loads are supported for both static and dynamic loads (see page 78 for a description on parallel dynamic loading).

Operating Mode Description

There are three basic operating modes: constant current (CC),

Constant Resistance (CR), and Constant Voltage (CV/CV+CC). All channels operate using any of the modes. Each mode has a number of configurable options including slew rate, levels, protection modes, Go/NoGo and extensive save options.

Constant Current Mode

Background

In Constant Current Mode the load units will sink the amount of current programmed. Regardless of the voltage, the current will stay the same. There are two ranges in CC mode: High and Low. There are two main modes in CC mode: Static and

Dynamic. Static mode can be used for stability tests and dynamic mode can be used to test transient load conditions.

Go/NoGo is supported for both High and Low range as well as Static and Dynamic mode.

CC Mode

PEL-2000 Series User Manual

Range

Static Functions

Static mode tests the stability of the voltage output from a power source. Single channel load modules can have two 2 current levels A (A Vaue) & B (B

Value). A & B have the same range. Pressing the

A/B key on the module load will cycle through the

A and B states. Alternatively, the mainframe can select A or B Value.

Dual channel load modules only have one current level (A Value) per channel in static mode.

Static Mode:

Single Channel

Load module.

There are two selectable ranges for constant current mode: high and low range.

Low range has a higher resolution, but a lower range. If the current exceeds the Low Range, High range must be used.

Dynamic

Functions

Dynamic load functions allow you to set load levels (Level1, Level2), load time (Timer1, Timer2), and the slew rate (rising, falling). Depending on the settings, the load will switch automatically between levels 1 and 2.

Dynamic loading can be used for charge discharge cycle testing etc.

62

Slew rate

The slew rate is the rate at which the current will increase to a set level. There are two slew rates: rising slew rate & falling slew rate. In CC mode the slew rate is defined as A/uS.

Go/NoGo

As can be seen above, the rising and falling slew rate need not be the same.

Using Go/NoGo, the Center, High and Low voltage limits can be set for both Static and

Dynamic modes. A delay time of up to 1 second can also be set.

Functions

CR mode supports Dynamic loading. Dynamic load has two resistance levels (Level 1&2), and two timers (Timer 1&2) to switch between the resistance levels. Rising and falling slew rates can be set to determine the speed at which the load generator switches between load levels.

Slew Rate

Go/NoGo

The rising and falling slew rate (A/uS) determines the speed at which the load levels change from A to B Value (Static mode) or from Level1 to 2

(Dynamic mode) and vice versa.

Go/NoGo is also supported. Center, High and

Low limits can be set as either percentages or voltage values. A delay time of up to 1 second can also be set.

PEL-2000 Series User Manual

Constant Voltage Mode

Background

In Constant Voltage Mode the load units will sink current whilst keeping the voltage constant.

Single channel load modules support 2 values (A

Value, B Value) and have an adjustable cut-off current limit. Dual channel load modules only have A value.

Response speed can also be set to fast (Fast) or slow

(Slow). The response speed relates to the slew rate of the current response.

Constant voltage mode only operates in high range.

Go/NoGo functionality is also supported either as a percentage or as a current value.

When the voltage input is greater than A Value

(load voltage) then the channel will operate in CV mode if the input current is less than the current limit. When the input current exceeds the current limit, the channel will operate in CC mode.

When the voltage input is less than A Value (load voltage) current stops flowing.

69

PEL-2000 Series User Manual

Response Speed

Response speed can be set to fast or slow. Fast response and slow response is determined by the load module specifications. Slow response speeds are suitable for large loads as quick current changes will induce induction which can cause large voltage drops. The PEL series will try to rectify any voltage drops. However if voltage drops are too large, they may cause the load generator to go into oscillation. Large voltage drops caused by line voltage induction may damage the machine.

Run Program

Background

The Program function on the PEL-2000 series supports a total of 12 different programs at any one time with 10 sequences to each program. Up to 12 programs can be chained together. The Program function is able to create a number of Go/NoGo tests.

Program

Sequence

A program sequence is simply a single load test. A program is a battery of each of these tests run in succession. Each sequence loads the settings for each channel from Memory Data (Memory MXXX).

The Memory Data stores settings such as the operating mode and range for each channel. Each sequence loads all channels at the same time, unless programmed otherwise. Sequences for each channel run synchronously.

Each Sequence has a number of configuration options that apply to all the channels equally.

Sequence 2 & 3 are skipped.

Program Chain

Any of the 12 programs can be chained together to create a Program Chain. Unlike Program

Sequences, Program Chains need not be run sequentially in numerical order. Any program can be chained to any program. It is possible to chain programs into an infinite loop to continue a program indefinitely.

Above, a program chain running sequences out-oforder.

PEL-2000 Series User Manual

Sequence

Background

The Sequence function is used to create high resolution load simulations. Each Sequence can be configured to create a unique load profile to accurately simulate loads in real time. Sequences are only applicable for CC (Static) and CR (Static) modes.

Note: Sequences are not to be confused with the sequences used to create a program. They are not the same and cannot be used interchangeably.

Sequences (SEQ memory) cannot be used in

Programs and Programs cannot load Sequences.

Load Profiling

The Sequence function is able to simulate a load to a high resolution. Each channel is able to change its load sink within 100us per point independently.

When used in parallel, multiple loads can be sunk concurrently to simulate the loads placed on multiple output power sources.

The diagram below shows the load profile of a

DUT at start-up.

74

Points

Up to 120 points can be used with each Sequence.

Each point can have a different duration, slew rate and value.

A new point can be inserted or deleted at any stage of a Sequence. Any new points that are inserted will have a value averaged from its neighbors as default.

Loop

A new point is inserted after Point 3.

Sequences can be programmed to loop a number of times starting from any point in the sequence.

From Point3 the sequence is looped two times.

On end load

PEL-2000 Series User Manual

If more than one Sequence is programmed on the mainframe, the On End Load function allows a

Sequence to configure its load on or off at the end of its sequence until the last sequence ends. After the last sequence ends, all loads are turned off.

This function is ineffective if only one Sequence is active. This is as the On End Load time and the time of the last sequence will be the same.

Trig Out

The Trigger Out function allows a trigger sequence signal to be output from a channel via PIN 4 on

Frame Link connector 1 when using Sequences.

The Trig Out function is used from the Channel

Duration menu.

76

As can be seen above, a trigger sequence signal is output for every rising edge point.

Channel Duration

Time Setting

The Channel Duration Time Setting feature allows the point time duration of one Sequence to be imported by another Sequence. If the receiving sequence doesn’t have enough points, more will be created (without values).

For example, the sequences for CH1 and CH2 are shown below. CH1 has a total of 6 points with long durations, whilst CH2 has only 2 points, looped 5 times. The points from CH2 are also significantly shorter in duration.

Below shows the resulting sequence when CH1 imports CH2. CH1 imports the duration time settings and number of points from CH2, but not the value data.

PEL-2000 Series User Manual

Parallel Dynamic Loading

Background

The PEL-2000 series of DC electronic loads support parallel dynamic loading. This simply means that when the load modules of a mainframe are connected in parallel and set to dynamic mode, they can perform dynamic tests synchronously following the same clock. Under dynamic mode, load current or resistance is pulsed between two preset levels. When used in parallel, higher powered outputs can be tested. This ability gives the PEL-2000 series the flexibility to perform dynamic tests over a wide range or power outputs.

For connection details see the Parallel Load

Connections section on page 52.

The diagram below shows how two load modules are able to sink a higher load when used in parallel under dynamic mode.

78

Configurations Description

There are a number of different configurations for the PEL series including protection modes, operating configurations, and file system configurations. The Configuration Description section describes what the different configurations are used for and how they can be relevant to different operations.

Protection Modes

Background

The PEL 2000 series include a number of protection modes: Over Current Protection, Over Voltage

Protection and Over Power Protection.

The protection modes are useful to protect both the load modules and the DUT(s). A buzzer can be set to notify when a protection setting has been tripped. When a protection feature is activated and has been tripped then the load unit will display an alarm. The Mainframe will also display an alarm.

When an alarm has been tripped the load will stop sinking current/voltage. There are three Over load protection settings: ON, OFF and Clear.

Reverse voltage protection prevents reverse voltage damage to the PEL-2000 series up to the specified rating. When Reverse voltage protection has been tripped an alarm tone will sound until the reverse voltage is removed.

Under voltage

Protection

For more details please see the specifications.

Under voltage protection will turn off the load when the voltage drops below a set limit.

Operating Configurations

Background

CC Vrange

There are number of operating configuration settings. Configuration settings are for the following:

CC Vrange, Von Voltage, Von Latch, Short Key, CH

Cont, Independent load sync, D-time and Step resolution settings.

CC Vrange (page 165) is used to set the voltage range as High or Low for CC mode. CC voltage range is dependent on the load module specifications.

81

PEL-2000 Series User Manual

Von Voltage

Von Voltage is the voltage limit at which the load will start to sink current. There are two operation modes for Von Voltage: Von latched:ON and Von latched:OFF.

Latched: ON will sink current when Von has been tripped, and will continue to sink current even if the voltage drops below the Von Voltage.

Von Latched: OFF will sink current when Von has been tripped, but will stop sinking current when the voltage drops below the Von Voltage setting.

As can be seen in the diagram below, when Von-Latch is set to off, the load module will start to sink current when the Von-voltage limit has been tripped. It will stop sinking current when the output drops below the

Von voltage limit.

82

Short

Note

CH CONT

Independent

When short mode is on, the load unit can simulate a short circuit.

Shorting can be individually set for each channel when programming sequences.

To initiate a short circuit manually, the short key is used. It can be used at any time during an operation. It will not affect the settings. After a short circuit has finished, the load unit will resume the previous operation.

The short key can be set to toggle or hold. When pressed in toggle mode, shorts are toggled on and off. When pressed in hold mode, the key needs to be held to short the load.

A short circuit may trip a protection mode if too much current is sunk.

Channel Control. When Channel control is activated (External) it can be used to monitor the voltage and current output of the load as well as turn loads on or off remotely from the Channel

Control (CH CONT) connectors located on the rear panel.

For more information about channel control, see external voltage control on page 85.

The Independent setting will allow the load modules to be controlled independently from the mainframe.

83

PEL-2000 Series User Manual

Load D-Time

Load Delay time is used to delay activating a load

(up to 10 seconds) after the load key has been pressed. However the Load D-Time setting will only work for loads that are initiated manually or when the PEL series mainframe is configured to

Auto load (page 182) at run time.

Step Resolution

Each channel voltage, current and resistance setting can have the step resolution configured.

For example if the step resolution for CCH (CC high range) is .5 A, then the resolution can be incremented in .5A steps;

8.08.59.09.5

The step resolution parameters apply to the following:

CCH Step – CC high range

CCL Step – CC low range

CRH Step – CR high range

CRL Step – CR low range

CV Step – CV high range

Step Resolution

Range

The step resolution range is dependent on the load module and the range:

Max resolution: channel range/4000

Min resolution: channel range/2

84

Channel Control

Background

External channel control is used with the Channel

Control connectors. Each channel control connector can activate each load, monitor voltage and current and has an external voltage reference input. The voltage and current monitors output 0~100% of the rated current/voltage as a voltage of 0~10V.

Turning on the

Load

A load is turned on when Load On input is set to

On (active low). A load is turned off when the Load

On input is set to Off (active high).

When a load is turned on from the channel control interface, the load can be turned off from the mainframe, local module and via remote control.

However the opposite is not true; when a load is turned off using the channel control interface, the load cannot be turned on via the mainframe, local module or via remote control.

Channel Duration Time Settings

Background

Each sequence can have the timing duration data of another sequence. For example CH1’s sequence can import the timing duration settings of CH2’s sequence.

This is useful to quickly compare two different loads to the same timing characteristics. See page

74 for more details.

Each channel’s sequence can be turned off by configuring the channel Setting to OFF. If a channel uses the same channel number, i.e CH 01

 01, then the duration time settings will not be altered for that channel.

One channel must output a Trigger Sequence

Signal via PIN4 of the frame link connector if a sequence is run. For more details see page 74.

Parameter

Any channels with channel control (CH CONT) set to external will be shown on the right side as EXT.

Q1. The load voltage indicated on the load module is below expected.

A1. Ensure the load leads are as short as possible, twisted and use the appropriate wire gauge. Ensure that voltage sense is used, this can help alleviate the voltage drop across the load the leads.

Q2. When I try to start a program sequence, it will not run. “No Active

Channel” is displayed.

A2. Ensure the channel(s) is activated (not set to OFF) in the

FUNCProgramActive Channel menu.

Q3. When trying to save to USB, the USB memory stick is unresponsive.

A3. Try restarting the PEL mainframe. If this fails to solve the problem, ensure the USB memory is cleanly formatted.

Q4. When I try to clear an alarm, it doesn’t work.

A4. Before clearing an alarm or using the Protection Clear All function, the load must be turned off. After the load is off, the alarm(s) can be cleared.

Q5. Settings aren’t saved to internal memory.

A5. If settings can’t be saved to internal memory, the internal battery may be flat. See page 243 for details.
