Lambda's PFE500F Brings More Functionality to its AC-DC Power Modules
SAN DIEGO, CA (June 05, 2008) - Lambda has extended its PFE series of "AC-DC full-brick power modules, unique to the market," 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
new 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.
The fully-regulated PFE500F models are available in 12V, 28V and 48V nominal outputs and can be adjusted over a ±20% range. The 12V PFE500F delivers up
to 504W with a maximum base-plate temperature of 85°C, while the 28V and 48V models deliver the same output at temperatures up to 100°C. Line and load
regulation is 0.4% and the efficiency exceeds 83% in all versions.
All models of the PFE500F accept a wide AC input from 85V to 265V at 47-63Hz, have active power factor correction, an input to output isolation of 3kV
and an enhanced input surge immunity level of up to 6kV with application circuitry. In addition, over-voltage, over-current and over-temperature
protections are included.
The PFE500F comes in a compact 4.8 x 2.76 x 0.5 inch package and can be cooled with an optional heatsink. All PFE500F models are delivered with Lambda's
two-year warranty, are safety-approved to UL60950-1, CSA60950-1 (cUL) and EN60950-1, and carry the CE mark.
The PFE500F series are available now with prices starting at $228.00 each in 100 piece quantities. Full specifications are available at:
