56RS3

300 Watt AC/DC Converter

NAI's 56RS3 is a rugged, high-performance 300W AC/DC power supply designed for aerospace, defense, and industrial markets. It can convert either three-phase AC input or +270VDC input into a single DC output. This COTS conduction-cooled converter provides a single full-power output of 300W at a baseplate temperature of +85°C or a single 350W output at a baseplate temperature of +70°C. The 56RS3 uses NAVMAT component derating and features remote error sensing, digital turn on/off (TTL), a Current Share option, and protection against input transients, over-voltage, over-current, and short circuits to ensure reliable performance in harsh environments.
