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 28V output.  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.
