These are
ultra-quiet, fully regulated switching
power converters (switchmode), designed
to allow the use of 12 volt equipment
in steel mills, mines, and other
systems where 250VDC is available.These
are attractive, reliable, robust DC/DC
converters. They have a high tolerance
for shock and vibration, are polarity
protected and dirty-power
protected.
To determine the
amperage you need just add up the watts
of all the 12V equipment and divide by
12 volts. These high voltage DC
converters have 3 year
warranty.
These rugged
converters are fully isolated. The
Steel Mill option includes immunity to
spikes up to 1000V.
