108V to 118V single phase 400Hz. For operation from 50/60Hz supplies can be accomodated by
means of an external capacitor. Please contact our sales office for further details.
MIL-STD-704E, Transients as per Figure 4, including voltage spikes specified in MIL-E-6051.
BS3G100, excluding limit 1 of variable frequency and limit 2 of variable or constant frequency.
Incorporates active Power Factor Correction circuitry and achieve power factors in excess of 0.95.

Not less than 70% at full load, nominal input voltage and at 25C baseplate temperature.
See output rating Table for details. Other V/A combinations are available. Contact sales team for
further information.
Prime Output
±2% of output voltage
Auxillary Outputs
±2% of output voltage
Measured over bandwidth DC-20MHz
Prime Output

Total combination of CEB + PARD + drift and warm-up.
Prime Output
±5% of output voltage
Auxillary Outputs
±5% of output voltage
Prime Output

Maximum transient over or undershoot of 5% of nominal output voltage for a 50% step load
change in 20
s. Recovery within 1ms.
Maximum transient over or undershoot of 5% of nominal output voltage with recovery within 1ms
for all line transients and surges defined in Input Power Characteristics above.
For full specified performance.
Prime Output
10% of maximum current.
Auxillary Outputs 10% of maximum current.
Individual outputs are protected against indefinite overload and short circuit. Current limiting
circuitry operates at 110-130% of full rated current. Output voltages recover automatically
following removal of overload.
Fitted as standard on the prime output only.
All outputs are protected by means of zener diode clamps. These limit the output voltage to
120%, typically, of the nominal value.
Under all conditions the converters start up in an orderly fashion. Rise time of supplies is less
than 10ms.
These modules can be synchronised to an external source or to other modules in the Powermite
range. (Synchronisation frequency = 400kHz
±5%)
