FCS3 Speed Controllers
FCS3*00 Speed Controllers
FCS: IP55 Three-Phase Speed Controllers
The three-phase series with IP55 index of protection are ideal for outside installation, and can be controlled by a 0 to 10 Vdc analogue signal from evolved controllers such as the FCM or pCO sistema, or by a PWM signal (pulse width modulation) from the MicroChiller series.
The range, which includes the control of motors rating from 6 to 40 A, features a control board that distributes the power to the load, in linear or quadratic mode, with the cut off, threshold, and minimum and maximum speed functions set using the trimmers on the board.
