2-3500 kVA
Servo controlled voltage regulations most widely used method in voltage regulation. We manufacture from 1 kVA to 50 kVA single-phase, from 2 kVA to 3500 kVA three-phase.
The voltage stabilizer basically consists of a variable transformer a servo motor that controls the variable transformer through a gear drive mechanism, a buck-boost transformer electronic circuit, and a sheet iron box that includes all.
Servo-controlled voltage regulator’s operation is based on feedback and comparison processes. Any voltage fluctuation in the network can be easily stabilized with the help of high response capability and ac/dc motor mechanism which have high start-up torque, even if the variation is very little.
Precision micro-switches are used as end limits for cutting off the energy of the motor when input voltage exceeds the regulation.
Output is sinewave with no distortion or interference in network frequency during operation.
Servomotors are generally used as a high performance alternative to ac/dc controlled stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps. This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. Our AVR-X logic card check online signals of voltage fluctuation and manage servo motors to make stable output voltage.
Available voltages: 220-400, 275-435, 310-450 VAC
Available voltages: 130-230, 160-250, 180-270 VAC
This device is equipped with a by-pass system that in case of failure can automatically disconnect the voltage stabilizer. The by-pass system saves your voltage stabilizer from suffering any damage.
The AVR-X is a next generation voltage regulator control unit combining multi-functionality and wide communication possibilities together with a reliable and low cost design. The unit complies and mostly exceeds world’s tightest safety, EMC, vibration and environmental standards for the industrial category. Software features are complete with easy firmware upgrade process through USB port. The Windows based PC software allows monitoring and programming through USB, RS-485,Ethernet and GPRS. The PC based Rainbow Scada software allows monitoring and control of an unlimited number of regulators from a single central location.
