Out of Stock

The AS-10 is a 12V DC automatic light control switch designed for outdoor street and area lighting. It uses a sealed CDS photoresistor to detect ambient light levels, automatically turning connected lights on at dusk and off at dawn, and is compatible with standard 10A lighting loads for energy-efficient automation.

Features

  • Automates lighting based on ambient light levels (dusk-to-dawn operation)
  • Handles high-power loads up to 2200W / 10A for street and area lighting
  • Features a 0.1s built-in delay to prevent false triggering from sudden light changes
  • Weather-resistant housing designed for durable outdoor installation on various poles
  • Simple two-wire connection for easy integration into 12V DC lighting systems

Description

The AS-10 Automatic Light Sensor Switch employs a precision CDS photoresistor sealed within a weatherproof housing to reliably monitor ambient light intensity. Its integrated control circuitry provides a clean, latching relay output to switch connected lighting loads, ensuring reliable dusk-to-dawn operation without manual intervention.

Engineered for outdoor durability, the compact sensor housing protects the internal components from moisture and environmental exposure, making it suitable for long-term installation on street light poles, in gardens, or along pathways. The 0.1-second activation delay is a critical feature that filters out transient light fluctuations, such as car headlights or lightning, to maintain stable switching performance and prevent nuisance cycling of high-power lights.

Key Features

  • High-sensitivity CDS photoresistor for accurate ambient light detection
  • Robust relay output rated for 10A / 2200W lighting loads
  • Integrated 0.1-second delay circuit eliminates false triggering
  • Weather-resistant and UV-stable enclosure for extended outdoor service life
  • Compact, low-profile design facilitates easy mounting on poles or walls
  • Simple two-wire installation (power and load) reduces setup complexity
  • Optimized performance-to-cost ratio for municipal and commercial lighting projects

Applications

  • Automatic control for municipal street lighting and highway lamps
  • Energy management for parking lot, pathway, and perimeter security lighting
  • Automated dusk-to-dawn operation for residential garden and landscape lighting
  • Lighting control in parks, schools, and commercial outdoor areas
  • Integration into solar-powered or off-grid lighting systems

Frequently Asked Questions

What is the operating voltage range for the AS-10 light sensor switch?

The AS-10 is designed for a 12V DC input voltage. It is not compatible with direct AC mains voltage. Ensure your power supply provides a stable 12V DC output to power the sensor's internal control circuitry and relay.

How do I wire the AS-10 sensor to control my lights?

Wiring is straightforward. Connect the 12V DC power source to the sensor's input terminals. Then, connect your lighting load (up to 10A) between the sensor's output terminal and the positive rail. The sensor acts as a switch, closing the circuit at dusk and opening it at dawn.

What does the 0.1-second delay feature do?

The built-in 0.1-second delay prevents false triggering. It ensures the sensor ignores sudden, brief changes in light intensity—such as from car headlights or lightning—preventing the lights from flickering on and off. It only activates the relay after the low-light condition persists for longer than the delay period.

Can this sensor be used indoors or is it only for outdoor use?

While its primary design is for outdoor applications due to its weather-resistant housing, it can be used indoors wherever automatic light control based on ambient brightness is needed, such as in warehouses with skylights or atrium spaces.

What is the maximum load this switch can handle?

The integrated relay is rated for a maximum load of 10 Amps at 12V DC, which corresponds to approximately 2200 Watts. Do not exceed this rating, and ensure all wiring and connectors are rated for the full load current to ensure safe operation.
