Model DC/DC 44LS1

100-Watt DC Power Line Conditioner w/Holdup

NAI’s 44LS1 is a 100-Watt Power Line Conditioner with holdup time that protects downstream DC/DC converters from transients, low voltage conditions, and power interruptions. This unit accepts +28 VDC input and provides 22.5 to 30 VDC at 100 Watts to all downstream DC/DC converters.

Designed to plug directly into a 3U cPCI chassis, the 44LS1 is conduction-cooled through the card edge/wedgelock. Standard features include continuous Background Built-in-Test (BIT), reverse polarity protection, an external ON/OFF switch, and holdup time.

The 44LS1 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.
