Twilight switch 16A U=12-264AC/DC Un=12-264V AC/DC~ Io<16A with hermetic probe, mounting on TH-35 rail AZ-B-PUS-UNI

Intelligent lighting control with twilight switch AZ-B PLUS-UNI

The twilight switch AZ-B PLUS-UNI is a reliable solution for automatic switching of lighting on and off depending on the light intensity. Ideal for home, commercial and industrial applications, such as garden lighting, driveways, building facades or storage areas. The device is mounted on a standard TH-35 rail, ensuring easy and quick installation in the distribution box. The set includes an external probe, enabling precise measurement of light intensity.

Versatility and reliability in every application. This switch will work in both simple home installations and more complex lighting control systems. Thanks to the wide range of supply voltage (12-264 V AC/DC) it is compatible with various power sources.

Functionality and user comfort

Thanks to the adjustable trigger threshold (2-1000 lx) and the on/off delay function (approx. 10s / 20s), the switch minimizes the risk of accidental switching caused by short-term changes in lighting, e.g. by passing cars or lightning. The external probe with IP65 protection rating ensures resistance to weather conditions, allowing it to be mounted outdoors. The setting of the switching threshold is done using a potentiometer - turning towards the “sun” delays switching on, and towards the “moon” - accelerates it.

Practical benefits for installers and users:

• Universality: Wide supply voltage range (12-264 V AC/DC) allows use in various installations.
• Easy installation: Mounting on a standard TH-35 rail facilitates and speeds up installation.
• Precise adjustment: Adjustable trigger threshold allows adaptation of the switch to individual needs.
• Weather resistance: External probe with IP65 protection rating ensures reliable operation even in difficult weather conditions.
• Energy saving: Automatic lighting control allows reducing electricity consumption.
• Increased safety: Eliminates the need to manually switch lights on and off, increasing comfort and safety.

Technical parameters and construction

The AZ-B PLUS-UNI switch has been designed with durability and reliability in mind. It uses a relay as a switching element, ensuring stable switching of a load up to 16A. The compact housing (2 modules – 35 mm) allows for efficient use of space in the distribution box. Made of high-quality materials guarantees long device life and resistance to mechanical damage. Screw terminals 4.0 mm² ensure a secure connection of wires.
