Characteristics

ZGR AVC DVR is an innovating system designed to mitigate and eliminate the effect of electrical disturbances on critical industrial processes through the elimination of sags and a continuous regulation for minor disturbances.

ZGR AVC DVR guarantees the quality of the grid meeting the demands of industrial production processes while keeping stable and constant the output voltage regardless of energy grid voltage variations.

It consists of a transformer, a bidirectional recti!er unit, plus an inverter. The aim of the ZGR AVC DVR is to compensate disturbances, unbalanced voltages, and to regulate them in case of possible “uctuations and overvoltages.

Moreover, ZGR AVC DVR monitors, controls and records events that occur in the system, allowing subsequent viewing through the touch control panel.
