Servo controlled voltage stabilizers


  1. Reliable READOUT, to read both voltage and current on the output side
  2. Complete IC version and electronic sensing
  3. Protective over voltage / under voltage trip facility and spike suppressor
  4. Precise electronic over load/ short circuit trip facility
  5. Suitably integrated to work even on non-sinusoidal waveform of generator etc.
  6. Audio annunciation on restoration of power to normality
  7. Multi socket output
  8. Very High Efficiency
  9. Distort free output wave form


A.C. Servo controlled voltage stabilizer to suit your need and budget -yet no compromise in performance and quality. Some models have the unique feature of measuring digitally both voltage and current on a single meter. Trouble free service and reliability makes our servo stabilizer most competitive and prominent in the indian market. Quality assurance by experienced engineers and dependable customer support service of our effective field staff are our plus points.
