March 17, 2014 - Addressing applications in fanless industrial, COTS, and communications markets,PFE300SA/500SA/700SA are conduction cooled via baseplate and incorporate PFC, regulation, and input-output isolation. All modules can deliver full power over -40 to +100C range (-40 to +85C for PFE500SA-12) from 61 x 12.7 x 116.8 mm package. Operating from universal input of 85–265 Vac (47–63 Hz), PFE300SA/500SA are available with nominal outputs of 12, 28, and 48 Vdc (51 Vdc for semi-regulated PFE700SA).

Higher Efficiency AC-DC Full-Brick Power Modules Have a Five Year Warranty

Press release date: March 1, 2014

TDK Corporation introduces the TDK-Lambda PFE-SA series of AC-DC full brick power modules, representing a significant upgrade to 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 85-265Vac (47-63Hz), 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 +100oC (-40 to +85oC 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.

More information can be obtained at the following TDK-Lambda Americas website,, or by calling 800-LAMBDA-4. Product availability for the PFE-SA series can be found via the link to TDK-Lambda’s distributor network (see “Check Distributor Stock to Buy”) at
