Table 1-1. Specifications
INPUT:
230Vac *10%, single phase, 57-63 Hz, 18A,
2500W @ 230V.
OUTPUT :
0-40 volts @ 0-50 amperes.
LOAD REGULATION:
Constant Voltage - Less than 0.01% plus 200µV
for a load current change equal to the current
rating of the supply.
Constant Current - Less than 0.02% plus 2mA
for a load voltage change equal to the voltage
rating of the supply.
LINE REGULATION :
Constant Voltage - Less than 0.01% plus 200µV
for a change in line voltage from 207 to 253 volts
at any output voltage and current within rating.
Constant Current - Less than 0.02% plus 2mA
for a change in line voltage from 207 to 253 volts
at any output voltage and current within rating.
RIPPLE AND NOISE:
Constant Voltage - Less than 1mV rms, 5mV
P-P (dc to 20MHz).
Constant Current - Less than 25mA rms.
TEMPERATURE RATINGS:
Operating: O to 55°C. Storage: -40 to +75°C.
TEMPERATURE COEFFICIENT:
Constant Voltage - Less than O .01% plus 200µV
change in output per degree Centigrade change in
ambient following 30 minutes warm-up.
Constant Current - Less than 0.01% plus 4mA
change in output per degree Centigrade change in
ambient following 30 minutes warm-up.
STABILITY :
Constant Voltage - Less than O .03% plus 2mV
total drift for 8 hours following 30 minutes warm-
up under constant ambient conditions.
Constant Current- Less than 0.03% plus 10mA
total drift for 8 hours following 30 minutes warm-
up under constant ambient conditions.
TRANSIENT RECOVERY TIME:
Less than 50µsec is required for output voltage
recovery (in constant voltage operation) to within
10mV of the nominal output voltage following a
S ampere change in output current.
METERS:
A front panel voltmeter (0-50V) and ammeter
(0-60A) is provided.
(Accurate within 2% of full
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.
