These are fully regulated switchmode power converters, designed to allow the
use of 12 volt equipment (or 24V equipment) in 72 volt trains. These are attractive, reliable, robust DC DC converters good for
locomotives, trams, golf carts, electric vehicles and power stations. They are typically used to power laptop computers, cell
phones, search lights, radios, wherever rugged 12VDC is required. They are ultra quiet, both in the input and noise fed back
into the input.
To determine the amperage you need just add up the watts of all the equipment and divide by 13.6 volts
(or 27.2 volts).
These converters have common negative, so they are not fully isolated, but can be used for almost all 12
volt applications. Fully isolated versions are available.
