Brick Model 56TS1

NAI’s 56TS1 is a 500 Watt AC/DC Power Supply that accepts a 3Ø AC input or a +270 VDC input. This COTS unit provides full-power output power at a baseplate temperature of +85° C.

Standard features include remote error sensing, Current Share, ON/OFF control; and protection against transients, overvoltage, overcurrent, and short-circuits. Additional options and special units can be ordered.

This conduction-cooled power supply is specifically designed with NAVMAT component derating for rugged defense and industrial applications. It is also designed to meet the many harsh environmental requirements of military applications. All units are 100% temperature cycled.
