EC fans, actuator powered dampers, control valves and many other devices require an analogue control signal of 0-10 VDC, 0-20 mA or PWM to regulate the fan speed or position between a minimum and a maximum value. Sentera offers a wide range of switches and potentiometers to manually generate a stepped or infinitely variable analogue control signal.
Passive control switches
Passive control switches are designed to manually adjust the speed of pole switching induction motors and can be used for AC fan speed control in steps.
