Industrial and military grade waterproof IP676 12 volt to 24 volt DC/DC Converters 32 Amp 850 Watt, or 15A 450 Watt

More DC/DC converters with 12VDC input and 1.5V, 5V, 6.5V, 8V, 10V, 11V, 12V, 13.8V, 14V, 15V, 16V, 18V, 19V, 20V, 21V, 24V, 27V, 36v, or 48V output

These DC converters are gasket sealed, and are fully IP676 ingress protected. They have a wide operating temperature range, and use a single military style circular bayonet connector for both input and output. designed to allow the use of 24 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.

To determine the output amps you need just add up the watts of all the equipment and divide by 28 volts.

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