Information
The following specifications describe the published
operational characteristics of this series of power supplies.
250 Watts nominal output.
AC Input: 250 watt model, 10 5™130V, 4 7-6 3Hz optional.
Units are shipped with terminal block, line cord available
on request.
REGULATION:
Voltage Mode: For line voltage variations and load current
variations within the rating of the supply, the output
voltage will not vary more than 0.1% of the maximum voltage
rating.
Current Mode: For line voltage variations and load voltage
variations within the rating of the supply, the output
current will not vary more than .25% of the maximum current
rating.
On those uni t s in which the percentage of voltage or
current ripple exceeds the specified regulation, the
regulation will appear to be degraded due to the effect of
this ripple on the measurement.
RIPPLE:
Measured with either positive or negative grounded and 100%
output voltage and cur rent into a resistive load. (See
rating chart)
(At 50Hz AC input is 30% above 60Hz rating)
The output voltage or current will remain within 0.05% for 8
hours after warm-up, with constant external effects.
TRANSIENT RESPONSE:
Upon instant application of of the maximum rating of output
voltage will recover its final value within 50ms line
variations are corrected to 1% within 50ms of their' occurrence.
TEMPERATURE COEFFICIENT:
Output voltage T.C. is 0.02% per degree C of maximum rating,
Output current T.C. is 0.03% per’ degree of maximum rating.
OPERATING TEMPERATURE:
0-50 Degree C (0-40 Degree C for 50Hz input with no derating
required. Derate current linearly to 50% of rating table
{pg. ) at 71 Degree C ambient.
STORAGE TEMPERATURE:
-10 Degrees to +85 Degrees C
GENERAL
RESOLUTION:
The voltage control is a ten turn potentiometer. The current
control is a one turn cermet type potentiometer.
