Lambda extends PFE series of AC-DC Full-BrickPower Modules

Tag : AC DC Inverter

Lambda has extended its PFE series of ac-dc full-brick power modules withthe introduction of the PFE500F that has additional featuresincluding active current-share and remote on/off. Like the existingPFE300S, PFE500S and PFE700S models, the new PFE500F versions aresaid to provide a convenient ac-dc board-mounted solution with anoutput power of up to 504W for applications in industrial, datacomand telecom equipment.

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

The fully-regulated PFE500F models are available in 12, 28 and 48Vnominal outputs and can be adjusted over a ±20% range. The12V PFE500F delivers up to 504W with a maximum base-platetemperature of 85°C, while the 28 and 48V models deliver thesame output at temperatures up to 100°C. Line and loadregulation is 0.4% and the efficiency exceeds 83% in all versions.

All models of the PFE500F accept an ac input from 85 to 265V at47-63Hz, have active power factor correction, an input to outputisolation of 3kV and an enhanced input surge immunity level of upto 6kV with application circuitry. In addition, over-voltage,over-current and over-temperature protections are included.

The PFE500F comes in a 4.8 x 2.76 x 0.5 inch package and can becooled with an optional heatsink. All PFE500F models aresafety-approved to UL60950-1, CSA60950-1 (cUL) and EN60950-1, andcarry the CE mark.

The PFE500F series are available now with prices starting at$228.00 each in 100 piece quantities.
