Owing to cutting edge production process, we deal in manufacturing quality standard automatic voltage controller (servo voltage stabilizer). We offer various types of automatic voltage controller including balanced type automatic voltage, automatic voltage controller with bye-pass arrangement, unbalanced type automatic voltage controller and automatic voltage controller with isolation. Entire range is appreciated for better efficiency, more energy saving, robust construction and long, trouble-free service life. Installation of the stabilizer with maintaining 390/400 volts assists in smooth operation of the motor drawing 15-20% lesser current. Further, the relay setting can also be reduced by 15-20% with the stabilizer installation. The relay will trip in 40-50 seconds in case of occurrence of single phasing. Our stabilizers also offer the motors to withstand the high current for this period and hence make it safe. In addition, the relays, contactors, switchgears and others outfitted with the motor will be safe.
