Characteristics
Remote Analog
Programming of
Output Voltage,
Current and Power
Independent Signal inputs for output voltage, current and power programming using
External Analog Reference.
Analog reference source is user selectable and can be a voltage, resistance or 4-20 mA
source. Selected analog reference source can be used to program output voltage, current
and power programming.
Voltage as Reference Source: 0 V to user selectable maximum range (2 V to 10 V) for 0 to
full scale rated Output
12
Resistance as Reference Source: 0 kΩ to user selectable maximum range (2 kΩ to 10 kΩ)
for 0 to full scale rated Output
12
Current as Reference Source: Fixed range from 4 mA to 20 mA for 0 to full scale rated
Output
Programming accuracy and linearity: ±1% of rated output
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.
