+5 VDC to +3.3 VDC 75-Watt Converter  6U VME

NAI’s 44KS2 is a 75-Watt DC/DC Converter that plugs directly into a standard 6U VME chassis with an 0.8” slot. It is conduction-cooled through the card edge/wedgelock. This switching power supply accepts a +5 VDC input and converts it to a single +3.3 VDC output at 75 Watts. The 44KS2 is ideal for powering single board computers or any other devices that require +3.3 VDC.

Standard features include status signals and indicators; and protection against overvoltage, overcurrent, and short circuits.

This COTS converter 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.
