EC fan controllers

A potentiometer generates an infinitely variable control signal, typically 0-10 Volt. This control signal can be used to control an EC fan, an AC fan speed controller, a frequency inverter or a damper actuator. Sentera has a wide range of potentiometers. Some potentiometers can generate different types of analogue signals, e.g. 0-20 mA or a modulating PWM signal. Some potentiometers require a supply voltage (24 Volt or 230 VAC), other types don't require a supply voltage.
