Excelsys announces XF-series high reliability, ruggedised AC-DC power supply

Excelsys Technologies have announced the introduction of the XF series of high-reliability, ruggedised AC-DC power supplies intended for harsh environments including Mil-COTS applications. The new XF family of power supplies provides from 400 to 1000 W, with efficiencies greater than 90% in an extremely compact 1-U x 268- x 127-mm package. Employing its innovative plug-and-play architecture, the XF family brings unprecedented flexibility that allows users to set a custom power configuration in less than 5 minutes. Designed to meet the demands of harsh operating environments, the XF family is ruggedised to withstand extremes in shock and vibration and is certified to Mil-STD 810G, Integrity Test for Vibration. Well suited to use in applications subject to extremes in temperature, the XF family will deliver up to 1 kW over a wide temperature range from -55 to 70 °C. All configurations carry full safety agency approvals, including UL60950 and EN60950 and are fully characterised for EMI according to MIL-461F. Other standard features include 47- to 440-Hz input frequency, 1.5- to 58-V standard output voltages, individual output control, complete field configurability, fully floating outputs allowing series/parallel connection for non-standard voltages or higher output current, paralleling of powerPacs for higher system power, 5-V, 250-mA bias standby voltage, and ultra-high efficiency up to 91%. Applications include harsh industrial, test and measurement, and fixed and mobile radar applications requiring COTS supplies. Excelsys
