AC-DC Full-Bricks Reach 91% Efficiency an Increase of 4%

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 +100 degrees C (-40 to +85 degrees C 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.
