This series of low profile 45-55 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.

Features
  • Low profile 0.500"
  • Low weight
  • Encapsulated semiconductors, conservatively rated for maximum reliability
  • Excellent voltage regulation
  • Excellent load regulation
  • Up to 55 watts output power at 70º C ambient
  • Low output ripple
  • Isolation: 1200V RMS
  • Single, dual and triple outputs
  • No heat sink required
  • Miniature size
  • No output capacitor required
  • Shielding


Low Capacity Option: All units can be manufactured with isolation capacity of 70pF. Contact factory.
