Applied for smooth speed control of EC motors with the control input 0-10 V.
Applied in ventilation systems for turning the fans on/off and speed switch of multi-speed fan motors.
Applied for speed ON/OFF switching and speed selection in the fans with multi-speed motors.
Applied in ventilation systems for switching ON/OFF and speed controlling of single-phase power-controlled motors.
Speed control enables not only selecting the comfortable ventilation mode for the periodically visited premises but reducing the energy consumption for the ventilation.
