Radio-controlled control unit for electronic ballasts. The DuoFern 1-10 V control unit is a radio-capable dimming actuator for electronic ballasts with a switching capacity of up to 1500 W. It is ideal for making your lighting radio-capable and achieving a professional smart home lighting control with LEDs or fluorescent lamps. Thanks to its compact and small design, it can be quickly and easily installed in a standard flush-mounted or electronic box. This allows the control unit to be mounted directly behind an existing switch or button, enabling you to operate your lighting manually in a traditional way or automate it via radio. The radio actuator is equipped with numerous features, including a soft start/soft stop function. Additionally, the dimming actuator has an intermediate value and staircase function.
