High Efficiency AC-DC Full-Brick Power Modules

The TDK-Lambda PFE-SA series of AC-DC full brick power modules from TDK Corp. are said to represent a significant upgrade over the popular PFE-S series launched five years ago.  These modules are particularly well-suited for outdoor and liquid cooled power systems, addressing the need for fan-less applications in the industrial, COTS and communications markets.

The new series achieves up to a 4% efficiency improvement (up to 91%) and has a five-year warranty. Like the existing models, the innovative PFE300SA, PFE500SA and PFE700SA bricks enable designers to utilize a single device containing power factor correction, regulation and input-output isolation.

Operating from a universal input of  85-265 Vac (47-63 Hz), the PFE300SA and PFE500SA models are available with nominal outputs of 12, 28 and 48Vdc (51Vdc for the semi-regulated PFE700SA model).  All the power modules can deliver full power with an operating baseplate temperature range of -40 to +100 oC (-40 to +85 oC for the PFE500SA-12) in a 61 x 12.7 x 116.8mm package.  In addition, over voltage, over current and over temperature protection is included.

The TDK-Lambda PFE-SA series is certified to the safety standards of UL/CSA/EN 60950-1 and is CE marked according to the Low Voltage and RoHS Directives.
