Fully Isolated Heavy Duty Industrial and Military Grade 24 volt to 24 volt DC/DC Converters 20 Amp, 540 Watt. 5 year warranty.

20 amp heavy duty DC/DC converter 24VDC to 24VDC

These are fully regulated switching power converters (switchmode), designed to provide regulated 24 volt power for equipment in 24 volt, and 28 volt, vehicles. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, construction, military, marine and recreational equipment. They are ultra-quiet both electrically and acoustically.

To determine the amperage you need just add up the watts of all the equipment and divide by 24 volts.

These converters are fully isolated, so will work in positive ground or negative ground applications.

How to use the dry contact relay

Dry Contact Relay: To use your dry contact output fail relay you must connect a 9-pin D connector to the unit. You must use pins one and six as is indicated on the remote connector diagram. The relay is factory preset to fail in the closed position when the low output LED and buzzer come on. If you wish to have the relay fail in the open position when the low output LED and buzzer come on, you must take the cover off the unit and move the jumper to the other position on J10. J10 is located next to the relay K1.
jumper position selection
To change the position of the jumper, first turn the unit off and disconnect the unit from both the power and load(s). Next, turn the unit on for 30 seconds to discharge the capacitors, then turn it off again. Remove the eight screws holding on the cover. Turn the unit upside down, remove the cover and locate J10. It will be next to the relay K1 as is shown in the above diagram. Simply move the jumper to the desired position as is shown in the above diagram. Replace the cover and re-install the eight cover screws. Reconnect the unit to the power and load(s).
