Remote Analog
Programming of
Overvoltage

Signal input for setting Overvoltage using External Analog Reference Voltage.

Range: 0.25 V to user selectable maximum range (2 V to 10 V) for 5% to 110% of the full-
scale Output Voltage.

Programming accuracy and linearity: ±1% of full-scale output

Monitor Signals
for the Output
Voltage, Current
and Power

Monitor Signals for the Output Voltage, Current and Power.

Full Scale range: 0 V to 10 V corresponds to 0-100% full-scale output

Minimum recommended Load: 100 kΩ, typical

Maximum Load: 20 kΩ

Monitor accuracy: ±1% of full-scale output

Remote ON/OFF

Control input for Output ON/OFF
Switch/Relay contact closure or direct short-circuit from this terminal to signal return will
enable (turn-on) the output of the supply
Remote circuit must sink up to 3 mA from 5 VDC to enable.

Isolated Remote
ON/OFF Control

There are two types of isolated control inputs to turn ON/OFF power supply

a) 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.

b) Isolated remote-control input for output on/off with a logic signal: a logic-high, 5

VDC TTL/CMOS signals will enable (turn-on) the output of the supply, and a logic-
low signal disables (turns off) the output

Note: These control input is optically isolated from the output power negative terminal of
the power supply (up to 500 VDC).

TRIGGER IN

Input signal, TTL active-high; provides external hardware triggering of voltage and current
ramp functions

Signal connects to Open-anode of opto-

isolator diode with internal 1kΩ series resistor

internal to power supply
Voltage Rating: Maximum 24 V, Minimum -5V
Low state 0.3 V max, High State 2.7 V min.

TRIGGER OUT

Output signal, active-low; synchronization pulse of 10 ms when a change in the output
occurs. There is an Option to feed User Power to the TRIGGER OUT signal.

Internal to power supply, signal output is from driver with input connected to open-collector
of opto-isolator transistor
Voltage Rating: Maximum 30 V, Minimum 4.5V for Active High, Current Maximum 0.5 A

FAULT

Output Signal, High state indicates fault state of the power supply. There is an Option to
feed User Power to the FAULT signal.

Internal to power supply, signal output is from driver with input connected to open-collector
of opto-isolator transistor
Voltage Rating: Maximum 30 V, Minimum 4.5V for Active High, Current Maximum 0.5 A

User
programmable
digital inputs

Four digital inputs to the power supply. Two of the digital inputs can be used as enable
signals for user programmable digital outputs.

Signal connects to Open-anode of opto-isolator diode with

internal 1kΩ series resistor

internal to power supply
Voltage Rating: Maximum 24 V, Minimum -5V

Low state 0.3 V max, High State 2.7 V min

User
programmable
digital outputs

Four  digital  outputs  that  can  be  enabled/  disabled  from  the  power  supply.  Two  digital
outputs  can  be  controlled  by  giving  appropriate  signals  on  User  programmable  digital
inputs.   There is an Option to feed User Power to these digital outputs.

Voltage Rating: Min 4.5V or User fed voltage minus 1 V. User fed voltage can be of
maximum 30 V.
