The range has a range of available voltages, multiple protections, and offers peak power capabilities up to 700W within a 500 µsec duty cycle.

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 Vac input-to-output isolation and an output-to-ground isolation of 1500 Vac. The series provides a universal 90~264 VAC input for global operation and comes available in eight separate single output models ranging from 12 to 54 VDC. 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. Pricing starts from $187.75 per unit (100).
