Mil/COTS Supply Delivers 1,000 Watts at -40C

Excelsys Technologies, Ltd. announced the availability of a new powerPac model in its popular XF series of high-reliability, ruggedized Mil/COTS modular power supplies. The new XFN powerPac is designed to deliver 1000W at -40 degrees C, therefore complementing the other products in the XF series that operate to -55 degrees C. Designed for use in harsh operating environments that do not require -55 C operation, the XFN powerPac is conformal-coated to withstand extremes in shock and vibration to MIL-STD-810G levels. It also carries full safety agency approvals including UL 606950 and is EMC characterized to MIL-STD-461F.

The XFN powerPac broadens Excelsys full line of XF power supplies that provide up to 1000W of power in a compact, 1U x 268-mm x 127-mm package. Employing an innovative plug-and-play architecture, XF power supplies accommodate up to six Excelsys powerMod output modules, which allow users to rapidly configure a custom power solution. Standard features in the series include 47-440Hz input frequency, 1.5-V to 58-V standard output voltages, and individual output control. They are completely field-configurable with an option to factory fix.

All outputs are fully floating to allow for series/parallel connection of multiple outputs for non-standard voltages or for higher-output-current paralleling of powerPacs for increased system power and efficiency. All models feature overvoltage, over temperature and overcurrent protection, provide a 5V/250mA bias standby voltage, individual output control of every output module, a market-leading five-year warranty and are SEMI F47 compliant.

“The new XFN powerPac model extends our already very successful XF family of configurable, ruggedized power supplies so that designers have the flexibility to select the most appropriate model for their requirements without over-specifying," says John Stevenson, VP North America, Excelsys. "Our XF family provides a single solution for complying with the vast majority of harsh environment Hi-Rel/COTS power requirements as well as a simple approach for users who need to configure for non-standard output voltages.”
