EC potentiometer

The EC potentiometer enables EC motors to be controlled with a 0–10 V control signal. A convenient knob allows fan performance to be adjusted practically within the 0–100% range. The potentiometer also has an additional switching contact that cuts off the voltage to the fans when their operation is not required.
