2.4 Remote Sensing

2.4.1 Correct Connection

1. Connecting remote sensing wire correctly can ensure the output voltage is the set voltage. The DC Power Supply is able to compensate maximum 4-10% of F.S. line voltage drop.

2. Figure 2-5 shows the correct connection. Use two wires to connect the positive/negative

connector of load to the remote sensing connector on the rear panel. The connecting wire diameter must be larger than 30AWG and its withstand voltage should be within the specification.

3. Though remote sensing is able to compensate the voltage drop; however, if the line loss

is too large (see specification) it will cause protection on remote sensing as Figure 2-6

shows and is unable to compensate voltage drop correctly.

Figure 2-5

Figure 2-6

2-5

Programmable DC Power Supply 62000H Series Operating & Programming Manual

2.4.2 Disconnecting Remote Sensing Wire

If the remote sensing wire is disconnected (means the two cables are open), it still works however the error range will be wider. The voltage measured from the output terminal is about 2% of F.S.; therefore it is necessary to connect the remote sensing wire correctly.

Please connect the remote sensing wire to output terminal even if the line voltage drop can be ignored in actual practice.

2.4.3 Reverse Connection of Remote Sensing Wire

Polarity

The polarity of remote sensing wire must be connected correctly, that is the “+” terminal is connected to the “+” of output terminal or to the connecting wire of the terminal, while the “–” terminal is connected to the “–” of output terminal or to the connecting wire of the terminal.

If the polarity is connected reversely, the output will drop to 0V and prompt an error message

“SENSE FAULT” as Figure 2-6 shows.

The DC Power Supply does not burn down due to reverse connection of polarity. Do the following step to reset it:

Remote Operation

5. Remote Operation

5.1 Overview

62000H Series DC Power Supply can be controlled remotely via USB, GPIB, Ethernet,

RS-232 or RS-485 port.

The USB interface supports USB 2.0/USB 1.1. GPIB interface is an 8-bit parallel data bus that synchronizes with the host bus commands. Ethernet interface is used in local area network for data transmission. RS-232C is a serial bus with less powerful functions; however, users can do remote control easily via simple programming.

5.1.1 USB Interface

(1) Hardware Support:

(2) Software Support:

(3) OS Support:

USB 2.0 and USB 1.1

USBTMC class and USB488 subclass

Windows 98/2000/XP/Vista

62000H Series USB Interface supports USBTMC, so if the PC

OS supports USBTMC (installed NI-VISA runtime version 3.00 or above) it is no need to install other drivers. The OS will search for the standard USBTMC driver installation program automatically.

If the PC OS does not support USBTMC, it is suggested to install the NI-VISA runtime version 3.00 or above first. When the installation of NI-VISA runtime is done, the USBTMC driver program is stored in OS. The PC can communicate with 62000H Series via NI-VISA after using the USB cable to connect them.

The character strings returned by query command are shown in either of the following forms:

<CRD>

<SRD>

Character Response Data: character string with maximum length of 12.

String Response Data: character string.

5.3.5 Basic Definition

5.3.5.1 Command Tree Structure

The commands of the DC Power Supply are based on a hierarchical structure, also known as a tree system. In order to obtain a particular command, the full path to that command must be specified. This path is represented in the structure by placing the highest node in the farthest left position of the hierarchy. Lower nodes in the hierarchy are indented in the position to the right, below the parent node.

5.3.5.2 Program Headers

Program headers are key words that identify the command. They follow the syntax

described in subsection 5.6 of IEEE 488.2. The DC Power Supply accepts characters in

both upper and lower case without distinguishing the difference. Program headers consist of two distinctive types, common command headers and instrument-controlled headers.

5.3.5.3 Common Command and Query Headers

The syntax of common command and query headers is described in IEEE 488.2. It is used together with the IEEE 488.2-defined common commands and queries. The commands with a leading “ * ” are common commands.

5.3.5.4 Instrument-Controlled Headers

Instrument-controlled headers are used for all other instrument commands. Each of them has a long form and a short form. 62000H Series only accepts the exact short and long forms. A special notation will be taken to differentiate the short form header from the long one of the same header in this subsection. The short form header is shown in characters of upper case, whereas the rest of the headers are shown in those of lower case.

5-5

Programmable DC Power Supply 62000H Series Operating & Programming Manual

5.3.5.5 Program Header Separator (:)

If a command has more than one header, the user must separate them with a colon

(FETC:CURR FUNC:SHAP). Data must be separated from program header by one space at least.

5.3.5.6 Program Message

Program message consists of a sequence of zero or other elements of program message unit that is separated by separator elements of program message unit.

5.3.5.7 Program Message Unit

Program message unit represents a single command, programming data, or query.

Example: VOLT?, OUTPut ON.

5.3.5.7.1 Program Message Unit Separator (;)

The separator (semicolon ;) separates the program message unit elements from one another in a program message.

Example: VOLT 80; CURR 15<PMT>

5.3.5.7.2 Program Message Terminator (<PMT>)

A program message terminator represents the end of a program message. Three permitted terminators are:

(1) <END> : end or identify (EOI)

(2) <NL> : new line which is a single ASCII-encoded byte 0A (10 decimals).

(3) <NL> <END> : new line with EOI.

The response message is terminated by <NL> <END> for GPIB, and

<NL> for RS-232C.

5.4 Traversal of the Command Tree

Multiple program message unit elements can be sent in a program message. The first command is always referred to the root node. Subsequent commands are referred to the same tree level as the previous command in a program message. A colon preceding a program message unit changes the header path to root level.

Example:

SOURce:VOLTage:SLEW 1

:SOURce:VOLTage:SLEW 1

All colons are header separators.

SOURce:VOLTage:SLEW 1;:VOLT 100

Only the first colon is a specific root.

Only the third colon is a specific root.

5-6

Remote Operation

5.5 Execution Order

The 62000H DC Power Supply executes program messages by the order received.

Program message units except coupled commands are executed in order of reception. The execution of coupled commands is deferred until program message terminator is received.

A coupled command sets parameters, which are affected by the setting of other commands.

Problems may arise, because the prior state of the 62000H DC Power Supply will affect the response of a coupled parameter to its programming.

5.6 Commands of DC Power Supply

This section describes the syntax and parameters of all commands for DC Power Supply.

5.6.1 Common Command Syntax

Commands are defined by IEEE488.2 standard containing common and query commands.

Common commands begin with a “*” and consist of three letters and/or one “?” (query).

6.2 Function Description

6.2.1 I/P (PFC) Stage

1. The input stage is a bridge rectifier to rectify the 3-phase power source to DC.

2. The way input stage inhibits inrush current is to connect the input circuit to a 40

Ω resistor in series during power-on to charge the input capacitor. Turn on the SCR after a few seconds and bypass this current limit resistor.

6.2.2 Auxiliary Power

1. The auxiliary power is the AC source input goes through the bridge rectifier and passes the flyback converter to get the desired output voltage. The PWM IC used is Unitrode

UC3845.

2. The output of auxiliary power is divided into three types of isolate power and they are named FSGND, OGND and DGND based on their potential. The FSGND is the fan reference potential of output stage, while OGND is the reference potential of output stage and DGND is the reference potential of digital signal and communication interface.

6.2.3 Output Stage

1. The output stage structure is full bridge that uses Unitrode UC3895 as PWM IC and controlled under voltage mode.

2. There are two output modes -- Constant Voltage (CV Mode) and Constant Current (CC

Mode) that switches automatically according to load state.

In Constant Voltage mode, following controls the IC detecting signal:

(2) The load actual voltage (remote sense) through output line, in which the remote sense can be disconnected but the accuracy will drop.

In Constant Current mode, following controls the IC detecting signal:

3. The secondary side is one stage LC filter to lower down the ripple voltage and ripple current.

4. The action of Dummy load is Constant Current Source and the Dummy load current will adjust following the output voltage. Moreover, it will act if the programmed voltage is less than the present output. The output has OVP and when it exceeds the OVP voltage (16 bit DAC) set by the front panel, the output will be disabled.

6.2.4 Digital Circuit

1. The digital circuit control unit is composed of TMS320VC5501ZZZ300 with Lattice FPGA

(LFXP2-8E-5FTN256C).

2. The power source 3.3V required by FPGA is got from +5VD.

3. The DSP required 3.3V and 1.26V power is got from +5VD.

4. The signal of analog program interface and digital circuit are isolated by the power source of +16VD with the free-run flyback converter and linear regulator.

5. The TTL output is +5V level and the internal digital signal is +3.3V level, therefore there are actions for level change.
