Ultra-quiet, precisely regulated
switching power converters (switchmode), designed to allow the use of even
power-noise sensitive 48 volt equipment in steel mills, mines, and other
systems where 125VDC is available. These are attractive, reliable, robust DC/DC
converters. Robust, with a high tolerance for shock and vibration, polarity
protected and dirty-power protected.
To determine the amperage you need
just add up the watts of all the 48V equipment and divide by 48 volts. These
high voltage DC converters have a 3 year warranty.
The Steel Mill
option includes immunity to spikes up to 1000V. These are also designed to be
used where permanent connection is desired.
