Description
1
Enable (input)
High = RUN = +5V to +15V
Low = OFF = 0V
The Enable function turns the output section of the power supply ON and
OFF. When the power supply is enabled, current is delivered to load as
programmed via Iprogram(+), Pin 7. Rise times resulting from Enable are
approximately 25msec.
2
V Program (input)
0 to 10V = 0 to full voltage
The power supply output coltage is set by applying a 0-10V analog signal to
Vprogram(+).
3
Interlock (input)
Open = OFF
Connect to GND = RUN
The Interlock function can be connected to external interlock switches such
as door or overtemp switches.
4
GND
Referred to (-) output of power supply.
5
Vout Monitor: (output)
0 – 10V = 0 – Voutmax*
The output voltage of the supply can be monitored by Vout Monitor.
6
Iout Monitor (output)
0 – 10V = 0 – Ioutmax
The output current of the supply can be monitored by Iout Monitor.
7
Iprogram: (input)
0 – 10V = 0 – Ioutmax
The power supply output current is set by applying a 0-10V analog signal
to Iprogram(+).
8
N/C
Do not use
9
GND
Referred to (-) output of the power supply.
10,11

12
-15V @0.2A(output)
Auxiliary -15V power supply for user. Up to 0.5A output current available.
13,14
+15V @0.2A(output)
Auxiliary +15V power supply for user. Up to 0.5A output current available.
15
Gnd
Referred to (-) output of the power supply.
