Functional Description

1

ISO

ON/OFF

Zin ~ 6 k

in

series with anode

of opto-isolator

LED

Isolated remote control input for output on/off with an applied
AC/DC voltage source. A positive (+) 6-120 VDC or an AC
input of 12- 240 VAC will enable (turn-on) the output of the
supply. This control input is optically isolated from the output
power negative terminal of the power supply (up to 500 VDC).
Signal return is Pin J1-2 (ISO RTN). See Section 3.13.

2

ISO RTN

Isolated signal return for on/off control using Pins J1-1 and
J1-14. Optically isolated from the output power negative
terminal of the power supply (up to 500 VDC).

3

REM OV

SET

Zin ~ 20 k

Control input for remote programming of the overvoltage
protection: 0.25-5.5 VDC = 5-110% of full-scale output
voltage. Reset of an OVP condition is possible by applying
an 10.5-13.3 VDC signal for 7 seconds. Signal return is Pin
J1-6 (COM). Circuit is electrically connected to the output
power negative terminal. See Section 3.12.

4

VP RTN

Zin ~ 10 k

Voltage programming signal return to be used with Pins J1-9,
J1-15 or J1-21; also must be externally connected to Pin J1-6
(COM) signal return when voltage programming is utilized.
Circuit is electrically connected to the output power negative
terminal.

5

ON/OFF

Zin ~ 10 k

pull-up to 15 VDC

Remote control input for output on/off: switch/relay contact
closure or direct short-circuit from this terminal to Pin J1-6
(COM) signal return will enable (turn-on) the output of the
supply; remote circuit must sink up to 1.5 mA from 15 VDC to
enable. Circuit is electrically connected to the output power
negative terminal. See Section 3.13.

6

COM

Signal return. Internally connected to Pin J1-24. Circuit is
electrically connected to the output power negative terminal.

7

I MON

Zout ~ 100

Monitor signal for output current: 0-10 VDC = 0-100% of full-
scale output current. Minimum recommended load resistance
is 100 k



Circuit return is Pin J1-6 (COM). Circuit is

electrically connected to the output power negative terminal.

8

V SET

*

Zout ~ 100

Monitor signal for front panel voltage potentiometer setpoint:
0-5 VDC = 0-100% of full-scale setpoint. Minimum
recommended load resistance is 100 k



Signal return is Pin

J1-6 (COM). Circuit is electrically connected to the output
power negative terminal.

9

VP 5V

Zin ~ 10 k

Control input for remote voltage programming using a voltage
source: 0-5 VDC = 0-100% of full-scale output voltage. Do
not exceed an input of 13.3 VDC. Signal return is Pin J1-4 or
Pin J1-20 (VP RTN). Circuit is electrically connected to the
output power negative terminal. See Section 3.11.

10

IP 5V

Zin ~ 10 k

Remote control input for current programming using a voltage
source: 0-5 VDC = 0-100% of full-scale output current. Do not
exceed an input of 13.3 VDC. Signal return is Pin J1-23 or
Pin J1-25 (IP RTN). Circuit is electrically connected to the
output power negative terminal. See Section 3.10.
