DC/DC power modules offer 90% efficiency

The TDK-Lambda PH-A280 DC/DC power modules are half the size of the previous generation devices and offer 5% higher efficiency.

The input voltage upper limit has also been extended to 425Vdc, making the PH-A280 suitable for the emerging 380Vdc power architecture used in data centres and telecommunications facilities. The power modules are conduction cooled, making them equally well suited to a range of industrial and renewable energy applications. Ranging in output power models from 50 to 150W with output voltages of 5, 12, 24 and48Vdc (up to ±20% adjustable), the PH-A280 complies with several safety standards, including UL/CSA/EN 60950-1 and CE, marked in accordance with the low voltage and RoHS directives. The devices are available in a 37.2 x 12.7 x 58.3mm package and come with a five year warranty.
