AC/DC power supply PFC 252R-F3-HSA

regulateddual-outputfor railway applications

The PFC 252R-HSA-F3 series dual-output railway AC-DC power supplies with pure convection cooling deliver up to 250W output power. The units employ active power factor correction (PFC) to convert a universal ac-input (95V to 264Vac) to two outputs. The PFC 252R-HSA-F3 AC-DC power supplies are designed for applications where a suitable heatsinking surface is not available and only pure convection cooling is feasible. A heatsink assembly is attached to the under-surface of the F3 power supply module, providing a pure convection cooled solution. This enables operation within a -40 to +55°C temperature range for full specification without derating.
