The THEBEN DM 8-2 T KNX is a versatile universal dimming actuator, ideal for controlling lighting systems in private households. With the ability to dim up to 8 different light sources, it offers a flexible solution for lighting living spaces, work areas, and outdoor areas. Whether dimmable LEDs, incandescent lamps, halogen lamps, or energy-saving lamps – the dimming actuator can control a variety of lamp types, ensuring a pleasant and adaptable lighting atmosphere.

A standout feature of the device is the automatic load detection. This function allows the dimming actuator to independently recognise connected loads and adjust the dimming curve accordingly. This not only ensures optimal performance but also extends the lifespan of the lamps. Manual operation directly on the device is particularly practical during installation and maintenance work, as it enables quick and straightforward control without requiring a central control system.

The LED switching status indicator is another useful feature of the dimming actuator. Each channel has its own LED display showing the current switching status. This facilitates monitoring and control of the lighting and ensures that the user is always informed about the status of the individual light sources.

An example application of the dimming actuator could be controlling the lighting in a living room. With the device, the user can individually adjust the brightness of the main lighting, the floor lamp, and the indirect lighting to create a cosy atmosphere for a movie night or a bright environment for reading. The ability to control different lamp types makes the dimming actuator particularly flexible and adaptable to the user’s individual needs.

Furthermore, the THEBEN DM 8-2 T KNX is compatible with the KNX system, enabling central control and automation. This means the user can control the lighting via a central control system or even through a smartphone app, provided it is set up. This integration into a KNX system offers not only convenience but also the possibility to create complex scenarios and schedules that automatically adjust the lighting to daily routines.

Another example of using the dimming actuator could be controlling the lighting in a bedroom. The user can individually set the brightness of the main lighting, bedside lamps, and indirect lighting to create a relaxing atmosphere for the evening or a bright environment for getting up in the morning. Manual control directly on the device allows the user to quickly and easily adjust the lighting without having to have the controls already parameterised for commissioning.

The low standby consumption of less than 1 watt also makes the THEBEN 4940285 energy-efficient and environmentally friendly. This is especially important for users who value sustainability and energy savings. Overall, the dimming actuator offers a wide range of applications and convenience for private users, particularly in intelligent home automation systems. With its versatile functions and easy operation, it is an excellent choice for controlling lighting in private households.
