SET DVR 30kVA 90kVA 60%

Dynamic Voltage Restorer For Industrial Applications

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.

Features

  • Compensation of voltage sags even for long times (up to 30 sec)
  • Swell compensation up to +20%
  • Compensation irrespective of phase
  • Compensation of balanced and unbalanced voltage drops
  • Automatic bypass
  • Withstand 150% overload for 1 sec
  • Less than 3ms response
  • Energy flow in both directions
  • Improved response in time
  • Reduction of operating costs
  • Guarantees maximum sturdiness of the system
  • Never interrupts service
  • Modular design which facilitates maintenance and repairs
  • Easy for connecting in parallel up to 3 equipments
  • Mitigate voltage sags according the standards: SEMI F47, IEC 61000-4-11 and IEC 61000-4-34 (depend on the model)
  • Turnkey project: tailor-made design for special needs
