Advanced unit rectifier assembly
The X-Pact® AURA as Advanced Unit Rectifier Assembly is designed to achieve efficient and stable power controller to feed DC arc furnaces in all power networks configurations, including weak grids. Based on modern IGBT technology, the new design achieves world class performances in terms of current stability, dynamic performances, efficiency, reliability, redundancy and minimum impact on electric network quality. In most cases, no SVC or Statcom is required to fulfill IEEE 519 standards.
