XP Power’s CCH400 and CCH600 series of compact, single-output, baseplate cooled 400 W and 600 W AC-DC power supplies are suited for harsh environment applications. With its highly efficient design, up to 90%, the CCH series generates substantially less waste heat than current product on the market, this being critical for use in 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 mm x 102 mm x 43 mm (8.43 inches x 4.02 inches x 1.69 inches), the compact CCH series is up to 50% smaller than other baseplate cooled products of a similar power level, allowing more space in the end-application or use of a smaller enclosure. With its high efficiency rating, a smaller heatsink can also be specified, reducing the overall footprint required.

Both 400 W CCH400 and 600 W CCH600 series accommodate the full universal input range of 90 V_AC to 264 V_AC without derating, making them suitable for designs used worldwide. These single output units are available with the popular nominal output voltages of +12 V_DC, +24 V_DC, +28 V_DC, or +48 V_DC.

Compliance to MIL-STD-461 for emissions and MIL-STD-810 for shock / vibration ensures 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 recognized safety standard EN/UL 60950-1 for IT equipment and meet EN55022 level B conducted and level A radiated emissions.

A fully featured signal set includes remote On/Off, remote sense, AC OK, and overtemperature warning and shutdown. A +5 V_DC standby output is also provided. A current sharing capability allows for parallel sharing of the load across up to three CCH units.

The CCH series has a wide operating temperature of -40°C to +70°C with a maximum baseplate temperature of +85°C.
