Twilight switch DEFENSOR

The DEFENSOR twilight switches reliably and discreetly increase safety around the building. Once darkness falls, they automatically or semi-automatically switch on the lights in the event of insufficient ambient lighting or can also be controlled via time-dependent operating modes. They therefore guarantee flexibility and energy efficiency, as well as protecting the relay during the operation of LED lights thanks to zero-cross switching. With the factory settings, the device can be commissioned immediately and the settings can be conveniently adjusted at a later date using the ESY Pen and ESY app.
