Output Filters and Reactors

Output Filters and Reactors

Output filters and reactors for motor protection and the improvement of system reliability, availability and functionality. Deployed at the output side of frequency inverters, these components ensure reliable operation by avoiding expensive downtimes of installations, manufacturing plants, machinery and a vast array of other industrial and domestic motor drive applications due to premature motor damage. An appropriate output solution will even allow the deployment of unshielded motor cables, the use of multiple motors in parallel on the same drive or the retrofit of modern drives in existing installations with old motors and unshielded cabling.
