Key Attributes of Servo Voltage Stabilizers
Servo Motor Technology
Using servo motors these stabilizers are capable of making instant and accurate adjustments to keep the output voltage stable.
Critical Applications
Designed for locations where sensitive devices and operations require an extremely stable power source.
Enhanced Performance
This is due to their quicker response times and higher load handling capacity. Servo voltage stabilizers are therefore preferred for critical and demanding applications.
Servo motor controlled automatic voltage stabilizer consists of following components
Buck/boost transformer:
Buck/Boost transformer connected between mains input and output of stabilizer of load terminals. One terminal of primary of buck-boost transformer permanently connected to fixed tapping of auto transformer (variac) while another end connects to motor shaft.
Auto transformer(Variac):
Autotransformer connected between neutral point and phase of input power supply.
Motor
One end of primary of Buck-Boost Transformer connected to shaft of this motor with arm and brush mechanism. When motor moves then this arm shaft moves across winding of autotransformer to increase or decrease number of winding. Motor is generally AC Synchronous Motor or DC Servo Motor which is connected and it is fitted on top of autotransformers centre point.
Motor driver
It is an electronic circuit which controls movement of motor. It consists of PCBs consisting of solid state circuitry made up of capacitor, registers, transistor, microprocessor and ICs.
Application scenarios
Industrial machines
They protect machines against fluctuations of voltage and optimize the efficiency of production.
Medical equipment
Ensure that the medical equipment is stable in voltage to guarantee the safety of the patient.
Computer systems
Supply stable power to the computer and servers to avoid losing data.
Communication systems
Provide constant voltage for communication equipment to be assured of reliable communication.
