This series of low profile 4555 Watt AC to DC switchers
come in 12 different models. These units offer high
efficiency and precise regulation throughout the operating
temperature range of 25º C to +70º C ambient, with no
heat sink or electrical heating required. The 50AC Series
keeps a maximum of 0.500" height while still offering you
1200 volts RMS isolation in a rugged encapsulated case.
The convenience of PC mounting and the availability of
three outputs should aid your circuit design.
