22
MON_RTN*
ANALOG GND
Return for Pin 6, 21, 35.
23
24
TRIG_OUT
DIGITAL OUT
User digital output, cause to be assigned by
user. Output high state either min 4.5V or
voltage on Pin 30 (USER_PWR) minus 1V,
whichever is higher. Maximum current of 0.5A.
25
DIO_OUT1
DIGITAL OUT
Output low for CV and high for CC. Output high
state either min 4.5V or voltage on Pin 30
(USER_PWR) minus 1V, whichever is higher.
Maximum current of 0.5A.
26
FAULT_OUT
DIGITAL OUT
High state indicates fault. Output high state
either min 4.5V or voltage on Pin 30
(USER_PWR) minus 1V, whichever is higher.
Maximum current of 0.5A.
27
DIO_OUT2
POWER OUT
Output low for CV or CC and high for CP.
Output high state either min 4.5V or voltage on
Pin 30 (USER_PWR) minus 1V, whichever is
higher. Maximum current of 0.5A.
28
RTN_UPWR*
POWER GND
Return for Pin 24, 25, 26, 27.
29
RTN_AUX5*
POWER GND
Return for Pin 43 (5V_AUX).
30
USER_POWER
POWER IN
Optional- User can connect between 5V to 24V
to control digital output/relay output voltage. If
left unconnected, digital and relay outputs
have 4.5V high states.
31
ON/OFF_ISO
DIGITAL IN
Isolated remote control input for output on/off
with a logic signal: a logic-high, 3.3V to 24V
signal will enable (turn-on) the output of the
supply, and a logic-low signal disables (turns
off) the output. This control input is optically
isolated from the output power negative
terminal of the power supply (up to 500 VDC).
Signal return is Pin 16 (RTN_HV).
32
33
PPRG_VSOUR/
PPRG_4-20mA_SOUR
ANALOG IN
Remote control input for power programming
using a voltage source: 0-5 VDC or 0-10 VDC
= 0-100% of full-scale output power. Do not
exceed an input of 12 VDC. Signal return is Pin
18.
34
PPROG_ISOUR
ANALOG OUT
Current source of 1 mA for remote power
programming using a resistance connected to
signal return Pin 18: 0-5 kΩ or 0-10kΩ = 0-
100% of full-scale output power.
35
PMON
ANALOG OUT
Monitor signal for output power: 0-10 VDC = 0-
100% of full-scale output power. Minimum
recommended load resistance is 100 kΩ and
maximum load is 20kΩ. Circuit return is pin 22.
36
RTN_UPWR*
OUTPUT GND
Return for Pin 37, 38.
