VARSine® – Static Reactive Power Generator

VARSine® is a static reactive power generator (SVG) designed to compensate for reactive energy consumed or generated in real-time by inductive or capacitive loads. It's the ideal solution for power factor correction in applications where the load varies rapidly (such as resistance welding, arc furnaces, refrigeration or compressed air compressors, etc.) or in networks heavily polluted by harmonics. It is designed with state-of-the-art technology based on high-performance IGBTs under a 3-level topology:

  • Rapid compensation of reactive energy
  • Harmonic compensation up to the 25th order
  • Load balancing between phases and neutral
  • Compact design, three-level topology
  • Expandable Modular System: up to 20 modules in parallel
  • Detection and protection against harmonic resonance
  • Integrated protection against network overloads, overvoltages, and undervoltages
  • Works in both 3-wire and 4-wire networks (configurable)
  • Simple and user-friendly HMI
Standards:
  • EN 62477-1(2012)
  • EN 61439-1 (2011)
  • EN/IEC 61000-6-4, Class A

The VARSine® Series Static Reactive Power Compensator operates on a three-level topology circuit. In addition to improving power factor, it provides energy quality solutions such as harmonic elimination and load balancing. It’s available in three versions: a wall-mounted enclosure version, ranging from 20kVAR to 100kVAR, a rack-mountable version for installation in standard 19” cabinets, ranging from 20kVAR to 100kVAR, and a cabinet version, ranging from 100kVAR to 400kVAR.

Its modular design allows users to easily achieve the desired reactive power by connecting up to 20 modules in parallel.
