pollution occurs. The pollution has no influence.
 Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
 Pollution degree 3: Conductive pollution occurs, or dry, nonconductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature

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

Precautions and Procedures
Introduction
The PEL-2000A 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-2000A 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-2000A, wire gauge
must be taken into account. Load wires must be
large enough to resist overheating when a shortcircuit 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.
45
PEL-2000A 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.

When using the PEL-2000A 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-2000A.
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.

The diagram above shows how changes in current can

when switching.

Remote (Sense) Connection
Background
WARNING
Connection
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, CR or
CP mode.
VsenseR (red) must have a higher (+) potential than
VsenseL (black).

Using the load generator with low voltage loads is
generally limited to over 1 volt (load module

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.

PEL-2000A 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 or CR 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 85 for a description on parallel dynamic
loading). Note that the same modules must be
used when operating the parallel.
The PEL-2000A also features a dedicated parallel
configuration setting known as Parallel Unit.
When Parallel Unit is turned on, load modules of
the same type and rating to be used in parallel for
CC and CR mode. See page 75 and 211 for more

Operating Mode Description
There are four basic operating modes: constant current (CC),
Constant Resistance (CR), Constant Voltage (CV/CV+CC) and
Constant Power (CP). 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.

Range
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.
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 Value) & 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.

resistance. CR mode has two different values
(single load modules), two different ranges and
rising and falling slew rates. Like CC mode,
Constant resistance mode supports both dynamic
and static loads. As with the other modes,
Go/NoGo is supported.

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.

Parallel Unit Mode
Background
The Parallel configuration menu allows load
modules of the same type and rating to be
configured as a single unit when used in parallel.
This saves the hassle of configuring each channel
individually.
Parallel Configuration is only supported under CC
and CR mode.
Parallel Configuration has three configuration
settings: Parallel Unit, Parallel Mode and Display
Mode.
Parallel Unit
This configuration setting sets the number units
that are to be used in parallel and enables or
disables the Parallel Unit mode.
Parallel Mode
The Parallel Mode setting determines how the
Current Levels/Resistance Values are set when
used in parallel. There are two settings: Para and
Sync.
The Para setting allows the all the parallelized load
modules to be operated as a single large load
module.
Sync mode allows the settings of a single unit to be
synchronized across all the other parallelized load
modules.

Run Program
Background
The Program function on the PEL-2000A 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

(page 75).
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.

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.

products. See page 179 for operation details.
This test will test to see when the over current
protection of a power supply is tripped and return
the measurements for the voltage and current
when the over current protection was tripped. The
PEL-2000A also has a user-defined OCP setting in
the event that the power supply OCP fails.

Parallel Dynamic Loading
Background
The PEL-2000A 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-2000A series the flexibility to perform
dynamic tests over a wide range of power outputs.
For connection details see the Parallel Load
Connections section on page 54.
The diagram below shows how two load modules
are able to sink a higher load when used in parallel
under dynamic mode.

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-2000A series include a number of
protection modes: Over Current Protection, Over
Voltage Protection, Over Power Protection, Under
voltage protection and Constant 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.

PEL-2000A Series User Manual
When a load unit is operating in CR, CV or CP
mode, the unit may need over current protection to
prevent excessive current being sunk. Over current
protection stops the load from sinking more current
than its recommended limit which can cause
damage to the unit.

Over Power
Protection
Over power protection is used when the power
range exceeds the specifications of the load. When
OPP is tripped power will cease to be sunk.
Reverse voltage
Protection
Reverse voltage protection prevents reverse voltage
damage to the PEL-2000A series up to the specified
rating. When Reverse voltage protection has been
tripped an alarm tone will sound until the reverse
voltage is removed.
For more details please see the specifications.
Under voltage
Protection
Under voltage protection will turn off the load
when the voltage drops below a set limit.

power draw.
Operating Configurations
Background
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, Step
resolution settings and Response settings.
CC Vrange
CC Vrange (page 192) is used to set the voltage
range as High or Low for CC mode. CC voltage
range is dependent on the load module
specifications.
89
PEL-2000A Series User Manual
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.
Von Voltage
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.

GETTING STARTED
Short
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.
Note
CH CONT
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 93.
Independent
The Independent setting will allow the load
modules to be controlled independently from the
mainframe.
91
PEL-2000A 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 217) at run time.
Step Resolution Each channel voltage, current and resistance setting
can have the step resolution configured. The step
resolution refers to the step resolution of the coarse
adjustment of these settings. The fine adjustment
cannot be configured, see page 202 for details.
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 The step resolution range is dependent on the load
Range
module and the range:
Max resolution: Module dependant, see page
202
Min resolution: Channel range/2
Response
92
The Response setting sets the bandwidth of the
load generator to 100kHz(normal) or 1MHz(fast).
The Response setting is particularly important for
limiting startup current.

Channel Control
Background
External channel control is used with the Channel
Control connectors. Each channel control connector

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.

Local mode operation is useful to quickly test loads using the load
module control panel rather than the mainframe control panel.
Local load modules can be configured to operate independently to
the mainframe. This can be useful when settings need to remain
unchanged on the mainframe. Note however that the local modules
cannot change the modes (CC, CV, CR, CP), only the values.
Parallel Unit mode is not supported for local module control.

Creating a Program Sequence
Background
The PEL-2000A series has a total of 12 different
programs and 10 sequences to each program. That
totals to 120 different configurations.
Each Sequence in each program uses the settings
saved from Memory Data (Memory MXXX).
Memory Data contains settings such as the mode

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
80 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 first frame link connector
(master) if a sequence is run. For more details see
page 80.
The Trigger In signal is used to start any sequence
that has TRIG set to IN. The trigger input signal is
input via PIN4 of the second frame link connector
(slave).
For more details, see page 80.
Any channels with channel control (CH CONT) set
to external will be shown on the right side as EXT.
See page 197 for details on setting channel control.

Background
Go/NoGo mode is used to set threshold limits.
When a load is within the limit(s) it is considered
to be “Go”, when the load has exceeded the limit it
is considered to be “NoGo”.
Go/NoGo limits can be set as either absolute
values (Entry Mode set to “Value”) or as a
percentage offset from a nominal (Center) value
(Entry Mode set to “Percent”).
Go/NoGo can be used in both high and low
ranges, as well as CC, CV, and CR modes. The
Go/NoGo status can be read using the rear
Go/NoGo output.
A delay time can also be imposed for up to 1
second.
Note
Any Go/NoGo configuration only applies to the
current channel with the same mode and range.

OPERATION
Parallel Unit
Background
The Parallel Unit Configuration menu allows load
modules of the same type and rating to be
configured as a single unit when used in parallel.
Up to 4 load modules can be used in this mode.
Operating the PEL-2000A load modules in Parallel
Unit mode is almost identical to using the load
modules separately. The only difference is that the
channel configuration only needs to be setup for
channel 1 and not individually for each channel.
There are two mode types: Para and Sync. The
Para setting allows the all the parallelized load
modules to be operated as a single large load
module. Sync mode allows the settings of a single
unit to be synchronized across all the other
parallelized load modules.
The Display Mode will determine which
parameters are displayed on the local load
modules.
Note
Only CC or CR mode can be used in parallel mode.
Parameters
Ensure the same firmware used for both units.

If you try to recall data that originated from a different
load module than the active channel, an error message
will appear. The filename must reflect the active
channel’s load module type.

FAQ
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.
