The original Powerflex PB350 was 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 PB350 design utilised a free running inverter with up to 6 plug in output modules based on mag-amp technology. Required cooling air was provided by a cover mounted DC fan.
