1kW power supply suits harsh environment electronics

The 1U XFN model features a 47-440Hz input frequency range, 5V/250mA bias standby voltage, 1.5-58V output voltages, individual output control and high efficiency of up to 91%. All outputs are fully floating, allowing series/parallel connection of all multiple outputs for non-standard voltages or higher output current. The power supplies can also be parallelled for higher system power and are field configurable (factory fix is also available as an option). The power supplies also feature over voltage, over temperature and over current protection.

The 1kW power supply is conformally coated and ruggedised to withstand extremes in shock and vibration to MIL-STD-810G levels. It carries full safety agency approvals including UL 606950, is EMC characterised to MIL-STD-461F and is SEMI F47 compliant for use in the semiconductor manufacturing industry.

“The XFN model extends our already very successful XF MIL COTS family of configurable, ruggedised power supplies and offers designers the flexibility to select the most appropriate model for their requirements without over-specifying. Our XF family provides a single solution to the vast majority of harsh environment MIL COTS power requirements and is simple for users to configure for non-standard output voltages,” commented Dermot Flynn, Sales Director, Excelsys Technologies.
