CUI Inc has added a family of compact 400 W AC-DC power supplies to its power portfolio. The PCM-400 series is housed in a U-frame package measuring 6 x 4 x 1.5 inches (152.4 x 101.6 x 38.1 mm). Featuring a wide range of available voltages, multiple protections and peak power capabilities up to 700 W within a 500 µs duty cycle, this series is ideally suited for numerous ITE, telecommunications, and industrial applications.

The PCM-400 power supplies meet EN60950-1 standards, carry UL/cUL and TUV safety certifications, and provide EN55022 class B EMI compliance. They feature 3000 V_AC input-to-output isolation and an output-to-ground isolation of 1500 V_AC.

The series provides a universal 90~264 V_AC input for global operation and comes available in eight separate single output models ranging from 12 to 54 V_DC. Dual-output versions are also available. The power supplies are rated for operation at full load from 0° to 50°C ambient, derating to 50% load at 70°C. Additional features include active PFC, remote on/off control and protections for over-voltage, over-current, short-circuit, and over-temperature.
