500 Watt 400Hz 3 Phase Input Single Output Military Grade Power Supply

Product Description

This unit is a 500 watt, 400Hz, 3 phase input, single output, military grade power supply designed for electronic systems operating in harsh environments (shock and vibration) and extreme temperature conditions. It is conduction cooled providing a -55° to +85° C operating temperature range. This product is based on predesigned board sections that are integrated into a sealed enclosure to meet or exceed applicable military standards including MIL-STD-810F & MIL-STD-461F.
