Servo Controlled Voltage Stabilizers

In the previous article (voltage stabilizers), we had seen how voltage stabilizers function, the difference between static voltage stabilizers and servo voltage stabilizers, and also understood the advantages and disadvantages. This article will focus more about Servo Controlled Voltage Stabilizers and discuss more about the technical aspects.

As we discussed earlier, servo voltage stabilizers (also known as automatic voltage stabilizers) are used for high power applications where a stable voltage is required, in spite of input line voltage variations and change in load. Servo Voltage Stabilizer ensures a high long-term stability of the output voltage.

It operates on a closed loop control. An electronic control circuit in the equipment measures the output voltage and compares with a high-stable reference. Whenever the output voltage deviates from the reference for more than 1% (industry standard), the servo drive (a motor) is switched on until the output voltage has again reached the nominal value. This results in a booster voltage, to be added to or taken away from the line voltage, corresponding to the deviation.

Servo Controlled Voltage Stabilizers consist of electrical and mechanical components, yet the design is so simple that it can be serviced by universally readily available skill sets.

Though the components are very simple, painstaking material selection and careful manufacturing process assure reliability, high effeciency and a long service life.

Most Servo Controlled Voltage Stabilizers are designed to operate under extreme climatic conditions, high voltage variations and operate round the year with low maintenance.

All over the world, the servo controlled voltage stablizers are used for protecting the equipments and places like:

• Hospital where precious medical equipments are installed
• Laboratories where precise testing equipments are used
• Industries where expensive CNC machines are used
• Electric heaters and boilers in the factories
• Data processing systems
• Radio transmission and receiving systems
• Radar systems
• Air conditioning systems
• All types of household appliances
• Sophisticated printing press equipments
• Accumulator charging equipment
• DC supply networks
