Absopulse Electronics Debuts PFC500-C Power Supply

April 21, 2004 by Jeff Shepard

Absopulse Electronics Ltd. (Carp, Ontario, Canada) debuted its new PFC500-C compact power supply intended for application in harsh environments where power-factor correction (PFC) is a key requirement. The unit is ruggedly constructed to withstand high levels of shock and vibration. The 5.2 in x 11.4 in x 2.75 in chassis is conduction-cooled via a base-plate, enabling operation over a –40 °C to +50 °C temperature range at full power without de-rating.

The design utilizes variable-frequency topology for the PFC-input stage, and half-bridge topology after the input stage to deliver 500 W from a 90 V to 264 Vac input (47 Hz to 420 Hz). The PFC500-C has an output fail alarm that signals 10 ms before the loss of output power. A built-in redundancy diode allows for parallel-connection to achieve higher output power or N+1 redundancy. This feature also makes the unit suitable for battery-charging applications.

The PFC500-C basic model is priced at $472 for quantities of one to four.
