P – SPECIAL CUT PHASE FAN SPEED CONTROLLER (ON DEMAND)

Controller P is a multifunction and multiple-input unit for the regulation of speed of asynchronous three-phase motors installed on axial fans. This device works as a voltage controller according to the cut phase principle (control over the three phases) in order to continuously increase and reduce the value of voltage supplied to three-phase AC motors [...]

Z – INVERTER SPEED CONTROLLER WITH SINUSOIDAL FILTERS INSTALLED

Inverter Z guarantees a remarkable energy saving and reduces the noise produced by the fans during the regulation phase. This is why it is ideal in environments with very limitating noise level restrictions.It is designed for the regulation of three-phase asynchronous motors mounted on heat exchangers. Suitable when low sound levels are required. TECHNICAL DATA [...]

G – STEP FAN SPEED CONTROLLER

Controller G is an electronic three-phase control unit designed according to the voltage step technology for accurate regulation, totally free of sound, electrical and electromagnetic disturbance. Thanks to this type of controller, effective voltage fed to the motor fitted in the fan varies according to fixed values that are determined by the steps featured in [...]
