1250 watt DC/DC converter 24V to 48V

These robust DC converters have a wide operating temperature range, and use a DIN terminal block for input and output connections. The wide input voltage range allows use in 24V or 24V systems, and designed to allow the use of 48 volt equipment in 24 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 48V.

These converters have common negative ground (non-isolated) and can be used for common ground and floating ground installations.
