  • utput

Unregulated

  • utput

Line with Photovoltaic power production Line with normal load

REDUCES COST

  • Doubling the capacity on existing cables

INTELLIGENT AND STEPLESS

  • Intelligent voltage reduction when required
  • Continuous fast self-regulating
  • Magnetic control - no voltage steps

FLEXIBLE

  • Separate connections for regulated and unregulated power outputs
  • Automatic bypass function
  • Off load tap changing possible
  • Fits in standard compact station housing
  • No need for adjustments, continuous fast self-regulating

ROBUST

  • Lifetime as standard transformer, no moving parts, no semiconductors

HIGH EFFICIENCY

  • Low losses in operation, bypassed when no voltage correction needed
