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.
