PFH500A-28-100-R is a PFH500A series AC-DC power module. It is used in environments where convection or forced air cooling is not viable. Suitable for use in applications requiring a nominal 400Hz input frequency, this PCB mounted power module accepts an 85 to 135VAC 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. This third generation modules also have a PMBus™ interface with read/write capability for remote monitoring and programming. It includes overcurrent, overvoltage and overtemperature protection. Applications include industrial, COTS, test and communication.
