## Long description

The F&F AZ-B PLUS UNI is a professional twilight switch engineered for the automated management of lighting systems based on real-time ambient light intensity. This device serves as a reliable solution for energy management, ensuring that connected lighting circuits activate precisely at dusk and deactivate at dawn. With its universal power supply compatibility and robust contact rating, it integrates seamlessly into various electrical installations.
Advantages
The primary benefit of this twilight switch is its exceptional versatility provided by the wide supply voltage range, which allows it to operate on both AC and DC systems from 12V to 264V. The adjustable sensitivity threshold offers precise control over when the lighting triggers, accommodating diverse environmental conditions from deep shade to bright twilight. Its high contact rating ensures durability and the ability to handle significant lighting loads without the need for additional contactors in many standard applications.
Suitable for
Automatic control of street and garden lighting
Illumination of building facades and parking areas
Energy-efficient management of indoor lighting in corridors or warehouses
Activation of advertising signage and display lighting
When it may not be suitable
This device is not intended for applications requiring complex time-based programming or astronomical scheduling, as it operates strictly based on light intensity levels. It may also be unsuitable for environments where rapid, flickering light changes could cause frequent, unwanted switching cycles.
Key specifications
Supply voltage: 12-264V AC/DC
Maximum load current: 16A
Sensitivity adjustment range: 2-1000lx
Operating temperature range: -25°C to +50°C
Mounting type: Surface or DIN-rail depending on housing configuration
How to use
The device should be installed in a location where the integrated light sensor is exposed to natural ambient light but shielded from the direct influence of the controlled light source. Once mounted, the sensitivity threshold is adjusted using the integrated dial to match the specific lighting requirements of the installation site. After the electrical connections are secured according to the wiring diagram, the unit will automatically monitor light levels and switch the output relay accordingly.
What to consider before purchase
Ensure the total power consumption of the lighting load does not exceed the 16A relay capacity.
Verify that the installation site allows the sensor to detect natural daylight without interference from artificial light sources.
Confirm the supply voltage of your electrical circuit matches the universal range of the device.
Usage recommendations
For optimal performance and to prevent false triggering, ensure the sensor is not placed in a position where it is directly illuminated by the light it controls or by other artificial light sources like street lamps.
