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.

Potentiometers - low supply voltage
Potentiometers that require a supply voltage in the range of 3 - 24 Volt. Often this voltage can be supplied via the EC fan or frequency inverter. Some of these potentiometers have Modbus RTU communication. This makes it possible to remotely monitor and control them. The splash-proof enclosure is suitable for inset mounting (IP44) or surface mounting (IP54). They generate an infinitely variable control signal, typically 0-10 VDC. This analogue signal can control EC fans, AC fan speed controllers or damper actuators with an analogue input.

Potentiometers 230 VAC supply voltage
Potentiometers that require a 230 VAC supply voltage. The splash-proof enclosure allows inset mounting (IP44) or surface mounting (IP54). They generate an infinitely variable control signal, e.g. 0-10 VDC, 0-20 mA or 0-100% PWM. This analogue signal can control EC fans, frequency inverters, fan speed controllers or damper actuators with analogue input.

Unpowered potentiometers
Unpowered 10 Kohm potentiometers. The generate an infinitely variable control signal. This analogue signal can control EC fans, frequency inverters, AC fan speed controllers or damper actuators with analogue input.
