High Power LRU Model 56WS2-01

NAI’s 56WS2-01 is a conduction-cooled, 1,500 Watt AC/DC Power Supply that converts either 3-phase, AC input or +270 VDC input into a single +28 VDC output at 1,500 Watts continuous or 3,000 Watts peak.

Standard features include remote error sensing; and protection against overvoltage, overcurrent, and short circuits.

This standalone 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.
