XP Power announced the CCH400 and CCH600 series of compact, single-output, baseplate-cooled 400 W and 600 W AC-DC power supplies suited to harsh environment applications.
With a design providing up to 90% efficiency, the CCH series generates little waste heat, making it suitable 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 214 x 102 x 43 mm, both the 400 W and 600 W series accommodate the full universal input range of 90 to 264 V a.c. without derating, making them suitable for designs used worldwide. They are available with the popular nominal output voltages of +12, +24, +28 or +48 V d.c.
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.
A fully featured signal set includes remote on/off, remote sense, AC OK and over-temperature warning and shutdown. A +5 V d.c. standby output is also provided, while current sharing capability allows for parallel sharing of the load across up to three CCH units.
