Control switches for EC motors or damper actuators
These control switches adjust the speed of EC fans in 3 or more steps. They can also control frequency inverters, fan speed controllers or damper actuators. They are available with or without OFF position. They divide the analogue 0-10 V control signal in three steps. This makes it possible to adjust the fan speed or the damper position from low to high in 3 steps.
