Minebea Electronics (UK) Ltd 50.5V – 56.5V 500W EP002G600RKE Switch Mode Power Supply
New unused old stock
Suitable as 48V battery charger for UPS or similar, high voltage FETs, RF linear amplifiers, regulated supply etc
100-240V 4A i/p, single DIN 41 612 connector
Electronic voltage control pin, current limit, over voltage and over temp protection

I have these as:

48V 10A set as fixed voltage (added a couple of resistors internally) - £17.50 ea

45V – 50.5V 10A, no voltage applied gives approx 38V regulated o/p,
with approx 5.5 - 11.5V applied to control pin, o/p varies between 45 - 50.5V - £15 ea

50.5V – 56.5V 10A, no voltage applied gives approx 43V regulated o/p,
with approx 5.5 - 11.5V applied to control pin, o/p varies between 50.5 - 56.5V - £12.50 ea

These would work really well with the adjustable constant current constant voltage power supply modules such as the DPS5015.

I have one myself hooked up to an ex mobile phone mast power supply and its works extremely well.
