DL series Three phase power filter

VVVF inverter is more and more widely used in elevator industry because of its many advantages. However, the interference caused by the harmonic of frequency converter seriously affects the normal operation of other precision instruments and electrical equipment in some occasions. In view of this situation, we developed a three-phase power filter in time, which has obvious effect on solving the system interference and the series connection between the systems, so that the superiority of the frequency converter has been given greater play.
