## Long description

The BEMKO A25-WZ38 is a high-performance twilight switch engineered for the automated management of lighting systems based on real-time ambient light levels. By monitoring natural light, this device ensures that connected luminaires are activated precisely when darkness falls and deactivated at dawn, promoting energy efficiency and operational convenience in both residential and commercial environments.
Advantages
This twilight switch offers significant benefits for users looking to optimize their energy consumption. Its robust 20A load capacity allows for the control of substantial lighting circuits without the need for additional contactors in many standard installations. The adjustable sensitivity range of 2-100 LUX provides the flexibility to fine-tune the activation threshold according to specific environmental conditions or user preferences, ensuring reliable performance regardless of the installation site.
Suitable for
Outdoor perimeter and garden lighting
Illumination of building facades and signage
Street and pathway lighting control
Automated indoor lighting for warehouses or hallways
When it may not be suitable
This device is not intended for use in environments where rapid, flickering light changes occur, as this may cause premature wear on the internal switching mechanism. It is also not suitable for applications requiring dimming functionality, as it operates strictly as an on-off switch.
Key specifications
Maximum load capacity: 20A
Adjustable light sensitivity: 2-100 LUX
Automatic day/night detection
Designed for standard electrical installations
How to use
The device should be installed by a qualified professional in a location where it can accurately detect natural ambient light without being obstructed by artificial light sources or shadows. Once mounted, the sensitivity dial can be adjusted to the desired LUX level to determine the exact moment of activation. After the initial setup, the switch operates autonomously, requiring no further manual intervention.
What to consider before purchase
Ensure the total wattage of the connected lighting does not exceed the 20A capacity
Verify the installation location is free from direct artificial light interference
Check that the mounting surface is suitable for the device dimensions
Usage recommendations
For optimal performance, position the sensor away from direct light sources such as street lamps or porch lights, as these can cause the switch to cycle on and off unnecessarily.
