Functional Description
8 Not Used

10 IP 5V Zin ~ 10k
Ω
Remote current programming using a 0-5 VDC source.
Do not exceed 13.3 VDC.

100
Ω
0-5 VDC (0-100%) front panel current control monitor output.
Minimum load resistance 10k
Ω.

Remote Sense (–) on 60 volts output units.
(For new installations, use J3, recommended only for
backward compatibility in existing systems.)

ISO
TTL/CMOS
Zin ~ 2.2k
Ω
Isolated TTL/CMOS on/off control. A high state TTL/CMOS voltage
turns on the power supply, and a low state or open connection turns
the supply off.
15 Not Used
16 IP 10V Zin ~ 20k
Ω
Remote current programming using a 0-10 VDC source.
Do not exceed 25 VDC.
17 FAULT
Zout ~
100
Ω
Fault state output. A high state (approximately +10 VDC)
indicates a converter, temperature or bias supply fault, and
the LED on the front panel will illuminate.
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.
19 V MON
Zout ~
100
Ω
Output voltage monitor. 0-10 VDC equals to 0-100% rated
voltage. Minimum load resistance 10k
Ω.
