The Innovative Controls Inc. 3050830 AC Controlled Power
Switch Module automatically selects the DC power source for the
sanitizer based on the state of the vehicle shore power.
When the vehicle is plugged into AC shore power, the sanitizer is
powered directly from the battery. When the AC shore power is
disconnected, the sanitizer is powered from the vehicle ignition
circuit.
The AC Controlled Power Switch Module contains hazardous
voltage. Contact with internal parts may cause electrical shock
and injury. Disconnect power before removing cover. No user
serviceable parts inside.
