  • Patent number: 9872360
    Abstract: An photocontroller with surge protecting function includes an photocontroller unit, a surge protection unit, and an photocontroller base. On the basis of an existing photocontroller unit and an existing photocontroller base, the surge protection unit is integrated inside the photocontroller unit or the surge protection unit can be connected in a plug-in manner. The surge protection unit is connected in parallel to a power supply phase line terminal and a neutral line terminal of the photocontroller unit. A ground line terminal of the surge protection unit is connected, by means of a ground connector, to the conductive part disposed on the photocontroller base. The conductive piece is grounded. The photocontroller and the surge protection function are combined, which can effectively discharge a surge current, suppress a surge voltage, is easy to mount and replace, and can reduce post-maintenance cost.
