Twilight switch with internal light sensor AZH - special design Un=12V~ Io<10A surface mounting AZH-12V

Twilight switch – intelligent lighting control

This twilight switch with an internal light sensor is a reliable solution for lighting automation. The device, operating at 12V AC/DC and with a load capacity of up to 10A, is ideal for controlling street lighting, squares, exhibitions, advertising, and also in home installations. Its compact dimensions (51 x 67 x 25.5 mm) allow for discreet surface mounting.

Functionality and application

The switch reacts to changes in light intensity, automatically turning on the lighting at dusk and turning it off at dawn. This ensures not only convenience but also energy savings. The built-in light sensor eliminates the need for additional control elements. Designed to operate in a wide temperature range (-25°C to 50°C) and resistant to atmospheric conditions (IP65), it guarantees reliable operation for a long time. Its construction based on a relay with one normally open contact (NO) ensures safe and efficient switching of the load.

Construction features and operating parameters

The housing made of durable thermoplastic provides durability and resistance to mechanical damage. The housing color (RAL 7035 – gray) facilitates integration with the environment. The device is characterized by an adjustable brightness threshold for switching on and off (2-1000 lx) and an on delay (10 s) and off delay (20 s), allowing for precise adjustment to individual needs. The halogen-free material of construction increases safety. The maximum switching power of the device is 2500W, and for LED loads – 150W. 12V AC/DC power supply provides flexibility in choosing a power source.
