A potentiometer is a device to generate a control signal. Typical control signals are: 0-10 VDC, 0-20 mA or 0-100 % PWM. These infinitely variable control signals or analogue signals can be used to control an EC fan, a frequency inverter, a variable speed drive, a damper actuator, etc. In simple words, this means that they can be used to manually adjust fan speed or damper positions. Some potentiometers require a supply voltage, while other types are 'unpowered' - these types don't need a supply voltage.
Brand new SDX fan speed controllersThe SDX infinitely variable fan speed controllers regulate the speed of small, single phase AC motors up to 3 Amps. Not only has the design of the enclosure been modernised, but also the electronics are brand new and offer many benefits. Especially the quieter motor operation at low speed is remarkable.>>>
