Power supplies for harsh environment and sealed enclosure applications

25 October 2012

XP Power's CCH400 and CCH600 series of compact single output baseplate cooled 400W and 600W ac-dc power supplies are suitable for harsh environment applications.

Offering an efficiency of up to 90%, the CCH series dissipates less heat, which is critical for sealed box applications. All heat-generating components are attached to the baseplate allowing heat dissipation through the sealed box chassis or heatsink. No forced air cooling is required.

Measuring just 214 x 102 x 43mm, both the 400W CCH400 and the 600W CCH600 series accommodate the full universal input range of 90 – 264Vac without derating. These single output units are available with the popular nominal output voltages of +12, +24, +28 or +48Vdc.

Compliance to MIL-STD-461 for emissions and MIL-STD-810 for shock / vibration ensure the CCH series is suitable for use in COTS military applications in addition to a broad range of industrial and commercial equipment used in outdoor and harsh environments.

The units also comply with the internationally recognised safety standard EN/UL 60950-1 for IT equipment and meet EN55022 level B conducted and level A radiated emissions.
