NEW MODEL 504W AC-DC Power Module

The 4” x 2.4” footprint, high efficiency PFH500 series of AC-DC power modules are used in environments where convection or forced air cooling is not viable. Suitable for outdoor enclosures or liquid cooled applications, these pcb mounted power modules accept a wide range AC input and deliver an adjustable, regulated 12, 28 or 48V outputs. High ambient temperatures can be tolerated as the conduction cooled baseplate can withstand -40 to 100°C temperatures. These next generation modules also have a PMBus™ interface with read/write capability for remote monitoring and programming.



  • 2.4 x 4” Brick Foot-print with Metal Case 
  • Load Share (optional)
  • High Efficiency 
  • PMBus™ 
  • Suitable for Conduction Cooling
