72 volt to 12 volt, DC/DC Buck-Boost converter at low
cost. Suitable for operating 12 volt consumer equipment in locomotives and trains which have a 72 volt DC starting
system
. These are regulated, switching power supplies or
DC/DC Converters.
Though the standard output is 12 volts,
there is a small range of voltage adjustment using a trimpot inside the unit, or you can specify a factory set output voltage
from 13.8 to 24 volts with a minimum order.
