METERS:
A front panel voltmeter (0-50V) and ammeter
(0-60A) is provided.
scale. )
OUTPUT CONTROLS:
Single-turn coarse and fine voltage and current
controls are included on the front panel.
OUTPUT TERMINALS:
Output bus bars are located on the rear of the
chassis. Both bus bars are isolated from the
chassis and either the positive or negative bus
bar may be connected to the chassis through a
separate, adjacent ground terminal.
REMOTE VOLTAGE PROGRAMMING:
All programming terminals are on a rear
barrier strip.
Constant Voltage - 1V/volt (accuracy: 1%).
Constant Current - 10mV/amp (Accuracy 10%).
REMOTE RESISTANCE PROGRAMMING:
All programming terminals are on a rear
barrier strip.
Constant Voltage -200 ohms/volt (Accuracy:
1%).
Constant Current -4 ohms/ampere (Accuracy
10%).
OVERVOLTAGE PROTECTION CROWBAR:
The minimum crowbar trip setting above the
desired operating output voltage" to prevent false
crowbar tripping is 5% of output voltage setting
plus 2 volts. Range is 4 to 45Vdc.
COOLING:
Forced air cooling is employed. The supply has
two cooling fans.
