These IP67 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 36V.
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.
