The AS-20 light sensor switch is a 10A, waterproof automatic photoelectric control switch designed to turn lights on at dusk and off at dawn, making it ideal for streetlights, gardens, and security lighting. It operates with 12V, 24V, 110V, or 220V AC/DC systems, reducing energy consumption and featuring built-in delay circuits to prevent false triggering.
Key Features and Specifications:
  • Voltage Options: AC/DC 12V, 24V, 110V, 220V
  • Maximum Load: 10A (Approx. 120W-2200W depending on voltage)
  • Functions: Automatic On/Off based on ambient light
  • Design: Waterproof, suitable for outdoor use
  • Delay Circuit: Prevents accidental activation from lightning or temporary light sources
Wiring Diagram:
The AS-20 typically has three wires for installation:
  • Black Wire: Power Input (Live/Line)
  • White Wire: Common Neutral (Input and Output)
