Overview
For an optimum performance of any electrical or electronic equipment it is highly important that the input mains voltage stability is maintained. Deviation from the normal voltage both on the higher side and lower side can produce harmful effects on the voltage sensitive devices. The solution to this problem is use of servo controller voltage stabilizer which guarantee that connected load will always operated within safe limits of voltage and thereby the machines to operate at a better efficiency hence avoiding losses.
Enertech entitles to be one of the leading manufacturers of servo controlled voltage stabilizer from Pune, India.
Using advanced micro controller based design the voltage stabilizer provides precise and accurate correction with a feature of auto calibration. It has an instant response using feedback mechanism to enhance the correction of automatic voltage stabilizer.
Enertech stabilizer provides with user friendly keypad and dashboard status to read input & output parameters.
