vepac-303-05-2014TDK Corporation has announced the successful development of the TDK-Lambda PH-A280 series of DC-DC power modules suitable for high input voltages, successors to the popular PH-S280 and PH-F280 series. The new product series is half the size of its forerunners with 5% higher efficiency (up to 90%). The input voltage upper limit has been extended to 425 V DC, making the PH-A280 suitable for the emerging 380 V DC power architecture, which is used in data centres and telecommunications facilities, where the use of higher voltage helps to reduce losses. The International Telecommunication Union Telecommunication Standardisation Sector and International Electrotechnical Commission are driving regulations for device specifications, system configurations, safety measures, and component/device specifications. Being conduction cooled, the new series is equally well-suited for a wide range of industrial and renewable energy applications, particularly in outdoor equipment that is water-cooled, hermetically sealed, of fanless construction and compact.
