Potentiometers with 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.
