Motor Protection

Chokes - Reactors - Toroids

The range includes various products for different applications.

As for the reactance on the line, solutions are available both for traditional and for regenerative systems with high frequency switching, especially with high frequency disturbance filtering.

Output Filter solutions include systems for use in open ring (Common Mode coil) or in closed ring systems (differential mode coils)

Inductors are available for both common mode and differential mode, the inductor models in differential mode are available to use with high frequency currents, such as occurs in applications using a synchronous motor, where the particular project has to contain to the minimum the effects of heating due to induced currents at high frequency. The sinusoidal output filters have two different lines, one for frequencies below 100 Hz, the other for higher frequencies, this second product line provides excellent performance in terms of minimum heating even without the use of forced ventilation.
