Datasheet

A 700W AC/DC full-brick power module, which provides users with a convenient AC/DC board mounted solution, has been released by TDK-Lambda. Expanding the company’s PFE-SA series of modules, the PFE700SA is 3% more efficient than the PFE700S, launched five years ago. The device is suitable for use in industrial, MIL-COTS, broadcast, datacomms, telecomms, test and measurement and LED display and signage applications.

Being a baseplate-cooled product, the PFE700SA is particularly well-suited for building into outdoor applications, as well as equipment requiring water-cooling, hermetic sealing, fanless operation and compact design.

Available in a 51V semi-regulated output, the power module can deliver full power with a baseplate temperature of between -40 and +100°C. Line and load regulation is 50 to 57V and typical efficiency for the PFE700SA is up to 91%.

As with all models in the PFE-SA series, the device accepts a wide, universal AC input from 85 to 265V at 47-63Hz, and features active PFC and an input to output isolation of 3kV for one minute. The inverter operation good functions provide great flexibility in the diagnostics of the power system. In addition, over voltage, over current and over temperature protections are included.

Offered with a five-year warranty, the PFE700SA conforms to EN/UL/CSA 60950-1 safety approvals for general purpose applications and carries the CE mark according to the low voltage and RoHS Directives.
