PFE-SA Series of High Efficiency AC-DC Power Modules with Conduction Cooling Developed

September 30, 2013

TDK Corporation announces the successful development of the TDK-Lambda brand PFE-SA series of AC-DC power modules designed for high efficiency. The new product series meets 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. Orders for the product, starting with the PFE500SA model, will be accepted by TDK-Lambda Corporation (President: Yoshiaki Hirota) from October 10, 2013.

In 2008, TDK-Lambda pioneered this field by releasing the one package unit AC-DC power module PFE-S series which was very well received. The new series represents an upgraded successor version. The new PFE500SA model reflects TDK-Lambda's latest technological know-how in high-efficiency design, resulting in a 4% improvement (series maximum efficiency 91%) over the predecessor.

This further facilitates thermal design of equipment in which the product is used, thereby contributing to the realization of more compact, more efficient, and more reliable systems. Dimensions and electrical specifications are compatible with the PFE-S series, to allow easy replacement from the existing series.

■ Major applications

General industrial equipment including automated devices for industrial and commercial applications, measuring instruments, ICT equipment, etc.

■ Main features and benefits

  • High efficiency: 91% (series maximum), 4% improvement over existing product
  • Replacement support: External dimensions, mounting dimensions, and electrical specifications are compatible with existing series

■ Major specifications: PFE-SA series
