0-5 VDC (0-100%) front panel current potentiometer set
point monitor output. Minimum load resistance
10k

Ω.

Circuit return Pin 6 (COM).

ISO

TTL/CMOS

Zin ~ 2.2k

Ω

Isolated TTL/CMOS on/off control. A high state
TTL/CMOS voltage enables the output, i.e., turns on the
output of the supply, and a low state or open connection
disables the output, i.e., turns off the output of the supply..
Circuit return Pin 2 (ISO RTN). See Section 3.7.

15 VP

10V Zin ~ 20k

Ω

Remote voltage programming using a 0-10 VDC source.
Do not exceed 25 VDC. Circuit return Pin 4 or Pin 20 (VP
RTN). See Section 3.5.

16 IP

10V Zin ~ 20k

Ω

Remote current programming using a 0-10 VDC source.
Do not exceed 25 VDC. Circuit return Pin 23 or Pin 25 (IP
RTN). See Section 3.4.

17 FAULT

Zout ~

100

Ω

Fault state output. A high state (approxi10 VDC)
indicates a converter, temperature or bias supply fault, and
the LED on the front panel will illuminate. Circuit return Pin
6 (COM).

18 S/D

FAULT

Zout ~

100

Ω

Shutdown fault. This terminal goes to high state in the
event of converter, temperature, overvoltage or bias supply
fault. A 7 VDC to 13.3 VDC signal can be applied to this
pin to shutdown the output of the unit. An 8 VDC minimum
output signal is provided into a 10 k

Ω

minimum load, in the

event of an internally generated shutdown. Circuit return
Pin 6 (COM). See Section 3.9.

19 V

MON

Zout ~

100

Ω

Output voltage monitor. 0-10 VDC equals to 0-100% rated
voltage. Minimum load resistance 10k

Ω.

Circuit return Pin

6 (COM).

20 VP

RTN Zin ~ 10

Ω

Voltage programming return. Used with J1-9, J1-15 or
J1-21 and must be referenced to Pin 6 (COM) circuit
common.

21 VP

RES

~ 10.8V

compliance

1 milliamp current source for remote voltage programming
using resistance. 0-5k ohm resistor referenced to Pin 4 or
Pin 20 (VP RTN) will program the output voltage from 0-
