TDK-Lambda PFH500F 500W High-Efficiency AC-DC Power Modules

TDK-Lambda PFH500F 500W High-Efficiency AC-DC Power Modules feature a 4″ x 2.4″ footprint and are designed for use in environments where convection or forced air cooling is not viable. Suitable for use in outdoor enclosures or liquid cooled applications, these PCB-mounted power modules accept a wide AC input range and deliver an adjustable, regulated output. High ambient temperatures can be tolerated as the conduction-cooled baseplate can withstand -40 to +100°C temperatures. These third-generation modules also have a PMBus™ interface with read/write capability for remote monitoring and programming.
