Potentiometer speed controller PO2

These controllers are designed for direct control or nominal value present of EC-fans with potentiometer input or any application where a DC control signal required. It is suitable for manual speed and air flow control on 0-15V output electrical fans. A supply voltage between 3 Vdc and 15 Vdc is required to provide an infinitely variable output signal between two internally selectable positions: V min and V max (adjustable). The device is additionally equipped with an enabling switch.
