The Zigor Power AVC SET DVR is an innovative system conceived and designed to mitigate or eliminate the effects of electrical disturbances on critical processes in industry by eliminating sags and continuous regulation of minor disturbances.

Energy generation, transport and distribution systems are limited and their instabilities can affect production processes in addition to having significant economic impacts.

It is composed of a transformer, reversible rectifier assembly plus an inverter, the purpose of which is to compensate for voltage disturbances and imbalances and regulate them in the event of voltage fluctuations and surges. The system also monitors and controls the events that occur.
The ZIGOR POWER AVC SET DVR ensures the quality of the network while respecting the demands of the industrial production processes.
