Electrical Characteristics
Remote Programming and Monitoring
Switching Frequency 7.5 V to 300 V models:
nominal 125 kHz (250 kHz output ripple)
600 V model
nominal 62.5 kHz (125 kHz output ripple)
Output Hold-up Time Greater than 10 ms with interruption of AC
line, for nominal AC input and full load.
Maximum Voltage Differential
from output to safety ground
±600 Vdc
Isolation Voltage Input to output: 1350 Vac
Remote Start/Stop and Interlock 2.5-15 V signal or TTL-compatible input,
selectable logic.
Input impedance: 1 k (in series with one
diode drop).
Remote Analog Programming
(Full Scale Input)
Voltage and current programming inputs
(source must be isolated): 0-5 k, 0-10 k
resistances; 0-5 V (default), 0-10 V voltage
sources;
Input impedance (V and I): approximately
475 k.
Remote monitoring Output voltage and current: 0-5 V, 0-10 V
(default);
Output impedance (V and I): approximately
221 Ω;
Output short circuit current: approximately
50 mA.
Remote Programming and
Monitoring Accuracy
1% zero to full scale output for the default
range.
Maximum Remote Sense Line
Drop Compensation.
(Line drop
must be deducted from the supply’s
maximum output voltage.)
7.5 V models: 3 V/line.
20 V to 600 V models: 5 V/line.
Isolated Program and Readback
(V & I) (Optional)
0-5 V (ISOL interface). Input impedance:
200 k.
Output impedance: 21 Ω
Digital Control (Optional) RS-232, GPIB or GPIB-M (multichannel)
