XP Power supplies target harsh environments

1 min read

XP Power has launched two new series of compact single output baseplate cooled 400 and 600W ac/dc power supplies, designed for use in harsh environments and sealed enclosure applications.

The CCH400 and CCH600 devices are said to generate less waste heat than comparable products and offer up to 90% efficiency. Heat generating components are attached to the baseplate allowing heat dissipation through the sealed box chassis or a heatsink, so no forced air cooling is required. Measuring 214 x 102 x 43mm, the supplies are said to be 50% smaller than other baseplate cooled devices of a similar power level. XP says this allows a smaller heatsink to be specified, which further reduces the footprint. Both series accommodate the full universal input range of 90 to 264 VAC without derating and are available with nominal output voltages of 12, 24, 28 or 48VDC. Complying with MIL-STD-461 for emissions and MIL-STD-810 for shock/vibration, CCH devices are suitable for use in COTS military applications and well as in industrial and commercial equipment.
