850 watt DC/DC converter 12V to 28V

These IP676 rated DC-DC converters are not hermetically sealed, but they are fully IP676 ingress protected, including immersion. They have a wide operating temperature range, and use a single military style circular bayonet connector which contains both input and output terminals. The wide input voltage range allows use in 12V or 24V systems, and designed to allow the use of 36 volt equipment in 12 volt, 14 volt, and 24 volt vehicles, 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 are 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 13.6V.

These converters are fully isolated and can be used for all 12 volt and 24 volt systems, including negative ground, positive ground, and floating ground installations.
