CUI – PCM-400 Series: 1U AC-DC Power Supplies Support Continuous Loads Up to 400W

CUI has introduced the PCM-400, a family of compact 400W AC-DC power supplies housed in four optional chassis-mount case styles.

The 1U u-frame (open-frame) version measures 6” x 4” x 1.5” (152.4 x 101.6 x 38.1mm). CUI also supplies enclosed versions with top or rear fan options.

Peak power output from the PCM-400 is 700W within a 500μs duty cycle, a rating that makes it ideally suited to applications in network and industrial equipment.

The PCM-400 power supplies conform to the EN60950-1 industry standards, and comply with the provisions of EN55022 Class B for EMI. They also carry UL/cUL and TUV safety certifications. They offer 3,000V AC input-to-output isolation and output-to-ground isolation of 1,500V AC.

All the PCM-400 power supplies operate from a 90 to 264V AC input, so that they can be run from a mains supply anywhere in the world.

The power supplies are rated for operation at full load at ambient temperatures from 0°C to +50°C, derating to 50% load at +70°C.
