The voltage input for the geoDVR Gen3 is variable and can be between 9V-32V DC. The average power consumption should be around 25 Watts. The max/peak power consumption is approximately 65 Watts (though 65 watts is probably way higher than the geoDVR will ever require).
The geoDVR Gen3 is usually shipped setup to start on ignition (basically, when the IGN input gets voltage (between 9-32V) for more than a couple of seconds, the geoDVR powers on). The common way most customers wire this is to put a on/off switch between the positive terminal and IGN terminal. This way, once the switch is turned on, the geoDVR will start.
IMPORTANT: If using the wall power adapter for testing do not use 220V (European, other standard for AC) directly – it will fry the unit. You will need a 110V converter. Once converted down to 110V AC, the power supplies we provided will then convert the voltages to do 12V DC which is the voltage the geoDVR requires.
