Twilight switch with internal light sensor AZH-C - special design Un=24V~ Io<10A surface mounting AZH-C-24V

Intelligent lighting control with twilight switch AZH-C

The twilight switch AZH-C is a reliable solution for automating outdoor and indoor lighting. The device, operating at 24V~ and with a load capacity of up to 10A, turns on the light at dusk and off at dawn, providing comfort and energy savings. The construction in a housing with an IP65 protection class guarantees resistance to weather conditions, making it ideal for outdoor applications - on building facades, in gardens or in squares. This allows installers to be sure of its long-lasting and trouble-free operation.

Functionality and application

The device is equipped with a built-in light sensor that precisely reacts to changes in daylight intensity. The brightness threshold for switching on and off is adjustable in the range of 2-1000 lx, allowing the automation to be adapted to specific environmental conditions and user preferences. On delays (10 s) and off delays (20 s) minimize the risk of unwanted switching caused by temporary changes in lighting, e.g. passing cars. This is particularly important for installers who care about system stability and customer satisfaction. The switch finds wide application in the automation of street lighting, advertising lighting, building facades and in security systems.

Construction and technical parameters

Made of durable thermoplastic, the switch is characterized by compact dimensions (81 x 35 x 25 mm) and easy surface mounting. It has one normally open (NO) contact, which facilitates integration with existing electrical installations. The maximum switching power is 2500 W for resistive loads and 150 W for LED loads. This allows one device to control different types of light sources. The halogen-free material ensures safe use and compliance with applicable environmental standards. 24V AC/DC power supply provides flexibility in choosing the voltage source, and the voltage supply tolerance (-15 ÷ 10 %) ensures stable operation even with slight voltage fluctuations in the network.
