Typical control signals are: 0-10 Volt, 0-20 mA or 0-100 % PWM. These continuous 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 to control a damper position. A potentiometer is often installed on an easy accessible location to remotely control fan speed or to regulate air flow by adjusting a damper position.
Some potentiometers require a supply voltage, while other types are unpowered.
Potentiometers are available in different enclosures. Most potentiometers can be surface mounted or flush mounted.
Most potentiometers generate a continuous variable output signal, but we also offer control switches that generate a 0-10 Volt signal in 3 adjustable steps. E.g. position 1 = 4 Volt, position 2 = 7 Volt and position 3 = 10 Volt.
