Servo Voltage Stabilizer (3-Phase)

Features

  • Fast correction speed up to 60V/sec. Variable speed servo motor and proportional control circuit provide a response time of 10msec to correct voltage fluctuations without noise or oscillations in output
  • Reduced power loss and resultant lower running cost yield higher cost savings and help the customer recover the cost difference in few months
  • Specially designed high performance controller based control circuit for ultra high reliability
  • All parameter like O/P V, I/P V, high, low cut-off, time delay, overload, set by front control
  • Accuracy ± 1% from no load to full load
  • Plug and play single control card for easy serviceability
  • Auto/Manual operation facility
  • High efficiency > 98%
