850 watt DC/DC converter 12V to 12V regulator 450 watt dc converter

These DC converters are not hermetically sealed, but they are fully IP676 ingress protected, which includes immersion up to 1 meter. They have a wide operating temperature range, and use dual military style circular bayonet connector for both input and output. The are designed to allow the use of regulated 12 volt equipment in 12 volt, 14 volt, and 24 volt vehicles, marine, military, 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.
The output voltage can be adjusted between 9.5V and 18V by removing the front cover. They have a wide range of input voltages, 10.5 to 32V, so cover the definition of buck-boost, where the input voltage can be either higher than or lower than the output voltage.

To determine the output amps you need just add up the watts of all the equipment and divide by 12.5 volts.

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