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 PH-A280 series of high-efficiency DC-DC power modules suitable for high input voltages. 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 PH150A280 model will be accepted by TDK-Lambda Corporation (President: Yoshiaki Hirota) from October 10, 2013.

The PH-A280 series succeeds the highly renowned and successful PH-S280/PH-F280 series, offering a 50% size reduction and 5% higher efficiency (series maximum 90%). In addition to this significant further improvement in basic performance, the input voltage upper limit has been extended to 425 V DC.

Besides earlier usage patterns such as for system power supply and distributed power Architecture, the new products are also suitable for HVDC (High Voltage DC Current) and solar cell related applications. Furthermore, the PH-A280 series offers the largest lineup of product versions in this category, which ensures that an ideal solution is available for a wide range of customer requirements.
