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.
