On average, these units consume about 35 watts, translating to under 3 amps at 12 volts and about 1.5 amps at 24 volts.

    Stay away from these product my experience has been less than enjoyable. From day one I had issues with the main board which was exchanged with a new one. A couple of years later the unit stopped working due to loose connection. Customer service is great BUT I care more for a reliable product which this is NOT.
