AS-10 12V DC Photoelectric Street Light Controller Automatic ON/OFF

The AS-10 12V DC Photoelectric Street Light Controller a light-sensitive component that changes its electrical state based on ambient brightness. When daylight falls below the sensor’s threshold, the controller closes its internal relay and switches the connected load on. When morning light rises above that threshold, the relay opens and the load switches off. The AS-10 12V DC Photoelectric Street Light Controller handles this entire cycle automatically with a 0.1 second response delay, which filters out brief shadow events from passing vehicles or birds without requiring any microcontroller or programming.

The auto day night sensor circuit inside the AS-10 operates at 220V AC across 50–60 Hz, making it a direct mains-level light on off switch for outdoor lighting circuits. Load capacity reaches 2200W — enough to handle multiple street light fixtures, LED flood arrays, or commercial signage panels on a single controller. The photo sensor switch detection range covers 10 metres, which suits pole-mounted installations where the sensor needs to read open-sky brightness rather than localised shadow. The photoelectric cell price at this load capacity makes it significantly more economical than installing timer-based or smart relay alternatives.

The light control switch function requires no wiring complexity beyond line, neutral, and load connections — the photo controls as-10 12v sits inline with the lighting circuit. The automatic daylight sensor eliminates human error in switching schedules, reduces energy waste from lights left on through daylight hours, and requires zero maintenance once calibrated. StemVolt provide this controller for Learners and enthusiast working on outdoor lighting automation and practical electrical projects.
