The original Powerflex P350 and P500 series were manufactured by Advance Power at their Bishop’s Stortford site for a number of years until the end of production in the early nineties. They were widely acclaimed for their inherent reliability and flexibility and were sold in relatively high quantities both in the UK and internationally.

The P350 design utilised a free running inverter with upto 6 plug in output modules based on mag-amp technology. There was the facility to configure some outputs as fully isolated and there was also the option of a dual output module. Required cooling air could be either customer supplied or provided by a cover mounted DC fan.

The P500 units were based on the same design with a higher current capability on the main output and the cover mounted fan being supplied as standard.

This product has been successfully trialled by the MOD and is accepted as a suitable replacement for P350 / P500.
