TDK-Lambda PFH500F-28 Series

The PFH500F-28 series utilizes GaN semiconductors, bridgeless power factor correction, synchronous rectification and digital control, enabling efficiencies of up to 92%. Opto-couplers have been replaced by digital isolators for long term reliability and stability. Accepting an 85 to 265VAC input, the modules deliver 28V at 18A and can be adjusted from 22.4 to 33.6V using the trim pin or PMBus interface.  Baseplate cooling allows operation at temperatures ranging from -40 to 100°C.  The metal enclosure measures 4 x 2.4 x 0.53” (101.6 x 61.0 x 13.3mm) and is encapsulated for MIL-STD-810G shock and vibration.
