Mini dimmer DIMAX 540 APP B: The world's smallest dimmer now it's really smart

Retrofit  without neutral conductor  but with app!

The new DIMAX 540 APP B mini dimmer for flush mounting from Theben brings more comfort and intelligence to older buildings – and in the smallest of spaces. It is based on the proven DIMAX 540 plus B, but significantly expands its range of functions: controllable via app, Bluetooth Mesh-enabled and with scene and astro functions – the problem solver for millions of old buildings is now even smarter.

Measuring just 32.5 x 26.6 x 9.6 mm, the new flush-mounted mini dimmer is hardly bigger than a 2-euro coin. 

Programming and operation are conveniently carried out via app using Bluetooth. 

Retrofit  without neutral conductor  but with app!

DIMAX 540 APP B vs. DIMAX 540 plus B – what's new?

Both versions are extremely compact, do not require a neutral conductor, and can be installed behind standard push buttons – major advantages, especially when retrofitting in existing buildings. The new DIMAX 540 APP B also offers:

  • App control: Convenient programming and operation via smartphone

  • Bluetooth Mesh: Devices can be networked with each other for greater range, reliability, and switchable scenes

  • Scenes and astro programs: Light can be customized even more

  • Advanced comfort functions: Night switch-off with astro function, power consumption display, date control

App control and Bluetooth Mesh

Programming and operation are conveniently carried out via app using Bluetooth. Any number of DIMAX 540 APP B devices can be integrated into the Bluetooth Mesh network. Communication via Bluetooth is efficient, secure, reliable, and boasts an extended range. Each device becomes part of a powerful network – they communicate with each other and pass on information. Even over long distances, through walls and floors. The signal always finds its way
—reliably, intelligently, and without detours.

Smart and secure – even in small spaces

Measuring just 32.5 x 26.6 x 9.6 mm, the new flush-mounted mini dimmer is hardly bigger than a 2-euro coin. The DIMAX 540 APP B is also suitable for two-way circuits with larger distances and multiple push buttons for cable lengths of up to 100 m. Thanks to its memory function, minimum brightness, overcurrent and temperature cut-off, it offers not only smart but also safe lighting control – ideal for living rooms, hallways or the modernization of entire buildings. Compared to other solutions, the mini dimmer is cost-efficient and flexible to use with little effort.

LED mini Dimmer DIMAX 540 plus B

The UP Mini Dimmer DIMAX 540 plus B measures just 26.4 x 25.5 x 10.4 mm. This makes it barely bigger than a two-euro coin. The 230 V mini dimmer for R and C loads does not require a neutral conductor and is simply mounted behind a standard push-button, making it perfect for retrofitting. If, for example, there is not enough space behind a built-in light switch to install a dimmer during a renovation or if there is no neutral conductor, the mini dimmer can be used. Thanks to its minimal housing, it fits into any switch box.
