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.
