The units meet the following requirements of
MIL-STD-461D CE101 (Figure CE101-4), CE102,
CS101, CS114 (Curve #3),CS115, CS116 (Air
Force).
Isolation:
All outputs have separate power returns to prevent
ground loops however there is no electrical isolation
between outputs and it is intended that power
returns are linked at the load.
Grounding:
The maximum dc resistance from the chassis to the
connector earth terminal is 20 milliohms.
Efficiency:
Not less than 75% at full load, 115Vrms 400Hz
input voltage and at 25C baseplate temperature.
Output Protection:
All outputs are protected against indefinite overload
and short circuit. The outputs have cycle by cycle
current limit operating at 110-130% of full rated
current. Recovery is automatic.
Output Overvoltage Protection:
The output voltages shall not exceed the values
shown below under any circumstances. If the
voltages reach these levels the unit shall trip and
latch off. An emergency operation override is
available.
