Single-phase electronic speed regulator 4 A

Manual voltage converter with continuous regulation by potentiometer. Electronic tuning by triac phase control closed loop type. Suitable for single-phase asynchronous adjustable motor.

Note: all regulators by triac control can cause electric hum in the motor at low speed. We advise against reducing under 50% the nominal speed of the electric motor. Motor electric hum can be minimized by using 3 wire capacitor/star winding.
