1,500-Watt AC/DC Power Supply, Air Plenum

Model AC/DC 56WS1-01

1,500-Watt AC/DC Power Supply, Air Plenum

NAI’s 56WS1-01 is an air plenum-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. This standalone device converts aircraft power so it can be used by system components.

Standard features include continuous Background Built-in-Test (BIT); remote error sensing; an elapsed time meter; a power-on self-test indicator; and protection against transients, over-voltage, and short circuits.

This AC/DC Air Plenum 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.
