20 amp heavy duty DC/DC converter, 250V input, 12VDC output

Heavy duty and steel mill DC converters


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.
