AVC SET 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.
Power generation, transport and distribution systems are limited and their problems can affect production processes as well as to produce economic consequences.
AVC SET DVR guarantees the quality of the network, meeting the demands of industrial production processes, keeping stable & constant the output voltage regardless of input voltage variations.
AVC SET DVR is a flexible voltage compensator capable of correcting variations of input voltage, to offer a highly stable voltage (± 0,5%) with immediate response (<3msec).
It consists of a transformer, a reversible rectifier unit, plus an inverter. The aim of the AVC SET DVR is to offset disturbances, voltage imbalances, and to regulate them in case of possible fluctuations and overvoltages.The system also supervises controls and logs all events.The output voltage stabilisation is assured both for balanced (all three phases) and unbalanced (some of the phases) voltage variations.
