These are fully regulated switching power converters (switchmode), designed to provide regulated 13.6 volt power for equipment in 72 volt trains, trams, mine carts and other 72V systems. These are, reliable, robust DC/DC converters. They are ultra-quiet both electrically and acoustically.

To determine the amperage you need just add up the watts of all the equipment to be powered and divide by 12 volts.

These converters are fully isolated, so will work in positive ground or negative ground applications.
