AC-DC power modules

June 9, 2008

Lambda has extended its PFE series of AC-DC full-brick power modules with the introduction of the PFE500F that has additional features including active current-share and remote on/off. Like the existing PFE300S, PFE500S and PFE700S models, the PFE500F versions provide a convenient AC-DC board-mounted solution with an output power of up to 504-watts for applications in industrial, datacom and telecom equipment.

The active current-share feature enables up to six PFE500F modules to be paralleled together to accommodate increased power requirements and/or redundancy. In addition, the positive logic remote on/off control and inverter-operation-good (IOG) functions provide greater flexibility in the start-up or shutdown sequencing and diagnostics of the power system. An auxiliary output of 10-14V at 20mA is included in the modules for powering external circuits.
