These are fully regulated
switchmode power converters, designed
to allow the use of 12 volt 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 (or 24VDC) 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 (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.
