Switching non-contact

Contact-free switched compensation devices are suitable for the applications, where quick change of the compensation power (welding devices, special drives, etc.) is requested. Compensation steps in protected version are used as a rule; the steps are not switched by the contactor, but by a contact-free switch. It is also possible to combine the contact-free switched steps with the contactor steps. The version is governed fully by requirements of the specific application. A special quick regulator is used for controlling or the signal is deduced directly from the compensated equipment. An example of solution of the contact-free compensation device can be seen in the Figure.
