Conduction-Cooled AD-DC Modules deliver up to 1kW
During this week's IEEE Applied Power Electronics Conference, TDK Corporation was demonstrating the new PFE1000FA line of conduction-cooled ac-dc power modules designed for high efficiency and high reliability. The new products meet various customer needs by providing support for outdoor equipment requiring water-cooled, hermetically sealed, fanless construction or compact equipment with high mounting density for which conduction cooling is most suitable. The modules, which measure 100 x 13.4 x 160 mm, began shipping to customers this month.
The PFE1000FA series is offered with three output versions: the PFE1000FA-12 rated for 12Vdc at 60A (720W) with a baseplate operating temperature range of -40 to +100 degrees C; the PFE1000FA-28 rated for 28Vdc at 36A (1008W) with a baseplate operating temperature range of -40 to +85 degrees C (for input voltages from 85- to 170-Vac) and -40 to +100 degrees C (for input voltages from 170- to 265-Vac); and the PFE1000FA-48 rated for 48Vdc at 21A (1008W) with a baseplate operating temperature range of -40 to +85 degrees C (for input voltages from 85- to 170-Vac) and -40 to +100 degrees C (for input voltages from 170- to 265-Vac).
With a minimum power factor of 0.95, the PFE series are power modules that combine a PFHC (Power Factor and Harmonic Correction) front end for stepping up the ac voltage with a dc-dc converter in a single integrated package. The flagship ac-dc power module PFE1000F originally introduced in 2008 now has been further upgraded and released as the PFE1000FA. These units meet the safety requirements of UL60950-1, CSA60950-1 and EN60950-1 (pending).
The highly efficient design achieved by harnessing sophisticated simulation technology and materials technology results in a maximum efficiency of 90%, which represents a 4% increase over the existing model. The new product further facilitates the thermal design of equipment in which it is used, thereby contributing to the realization of more compact, more efficient, and more reliable systems. Dimensions and electrical specifications are compatible with the existing model (PFE1000F), to allow easy replacement from the old type.
