Radio-enabled control unit for electronic ballasts. The DuoFern 1-10 V control unit is a radio-enabled dimming actuator for electronic ballasts with a switching capacity of up to 1500 W. It is ideally suited to make your lighting radio-compatible and to implement 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 in a traditional manual way or to automate it via radio. The radio actuator is equipped with numerous functions, such as a soft start / soft stop feature. Additionally, the dimming actuator has an intermediate value and stairwell function.
