Applied in ventilation systems for speed switching ON/OFF and speed control of single phase power-controlled motors. Several fans can be controlled synchronously in case their total current does not exceed the maximum permissible value of the controller current.


Input circuit of the speed controller has a thermal fuse for overload protection. The controller is fitted with a transient filter.


The controller casing is made of pastic. Equipped with the pilot light. The controller is featured with high efficiency and control accuracy. Regulating starts from the minimum to the maximum voltage value for the fan stable running. The minimum speed is set by means of the potentiometer at the PCB. The controller is equipped with extra 230 V terminal for connection of the external equipment.


The universal design of the controller enables its mounting either on the wall or through the wall, suitable for installation into standard round electric junction boxes.
