basic components of servo voltage stabilizer are

  • buck boost double wound transformer.
  • suitable toroidal wound variac.
  • geared servo motor unit with limit switches to avoid over running at highest and lowest position.
  • microcontroller digital display control card.
  • these entire components are interconnected to form servo voltage stabilizer.

salient features

  • wave shape distortion-nil.
  • 95% and more efficiency being achieved by optimum design and by use of high quality crgo lamination and 99.9% pure copper.
  • immune to load pf and supply frequency variation.
  • power losses 2% maximum.
  • duty cycle continuous.
  • life expectancy 15-20 yrs.
  • operation-auto/manual.
  • control through micro processor controller/ic based solid state plug in type glass epoxy control card.
  • high quality ehv grade oil as per is-335.
  • reference standard is-9815, is-2026.
