High Efficiency PFE-SA AC-DC Modules

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 85-265 VAC (47-63 Hz), the PFE300SA and PFE500SA models are available with nominal outputs of 12, 28 and 48 VDC (51 VDC for the semi-regulated PFE700SA model). All the power modules can deliver full power with an operating baseplate temperature range of -40 to +100°C (-40 to +85°C for the PFE500SA-12) in a 61 x 12.7 x 116.8 mm 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.
