How to control a damper position?

EC fans, frequency inverters, fan speed controllers, damper actuators and many other devices require an analogue control signal, e.g. 0-10 VDC, 0-20 mA or 0-100% PWM to regulate the fan speed or damper position between a minimum and a maximum value. Sentera offers a wide range of control switches and potentiometers to manually generate a stepped or infinitely variable control signal.
