AC INPUT:
90 to 132 and 180 to 265 Vrms, 47 to 400Hz,
single phase. Dual input selectable
EFFICIENCY:
75% Typical, 70% Minimum
LINE REGULATION:
0.12% for full input charge between 90 and
132 or 180 and 265 Vrms. Temperature
and load constant.
LOAD REGULATION:
0.2% for change from no load to full load
(100%) with line constant.
RIPPLE AND NOISE:
50mV peak-to-peak typical. 100mV
peal-to-peak maximum measured
with a 25 MHz bandwidth.
OPERATING TEMPERATURE RANGE:
0ºC to +85ºC
ISOLATION:
Input to Output 1000 VDC
Input to Case 1000 VDC
Output to Case 500 VDC
SHORT CIRCUIT PROTECTION:
Each unit is completely protected against a
short circuit of any duration. The constant
current circuit is nominally set at 120%
of fill load to reduce voltage. The output
voltage automatically restores to
normal when the short is removed.
REMOTE ERROR SENSING:
Regulator monitors the voltage directly at the load
of voltage using extra “Sensing” leads. The resulting
circuits action compensates for a DC voltage drop up to 0.3
Volts in the load leads.
INPUT PROTECTION:
Internal fuses, 115V 5 amp. 230V, 2.5 amp
