Mains chokes (commutating reactor), common mode chokes, motor chokes and many more..
With our experience and expertise, we are able to design and manufacture custom-made chokes especially for your application. We have already developed various mains chokes or common mode chokes and delivered them to the satisfaction of our customers. We are also specialised in the field of filter applications, for example in the form of sinusoidal filters. The highly complex requirements in throttle and filter design and dimensioning drive us every day and allow us, together with our customers, to achieve great things.
Below you will find a small extract from our program:
