400 watt potted DC/DC converter 12V to 48V

These DC boosters are designed to allow the use of 48 volt equipment in 12 volt, marine, military, boat, yacht, PLC, and cell tower applications. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, construction and recreational equipment. They potted to be relatively immune to vibration and shock.

To determine the output amps you need just add up the watts of all the equipment and divide by 48V.

These converters are common negative, and are useful for most 12-48V conversion applications.
