Voltage fluctuation is common problem for industrial and commercial sector in India and it cause damaging of various industrial equipments and domestic appliances. Because of this variation circuit of device will burn or cause short circuiting. Here stabilizer provides solution as it protects our equipments from voltage fluctuations and provide constant flow of voltage after stabilizing the voltage supply. Stabilizers are classified as per their application. Most common used stabilizers offered in Indian market are servo voltage stabilizer and static stabilizer. These stabilizers are made to provide continuous input voltage and by this way we can decide which stabilizer is best for our particular application.

 Servo voltage stabilizer consist a servo motor for stabilizing the voltage supply. Along with servo motor, stabilizer circuit and buck- boost auto transformer also help to correct input voltage fluctuations and supply at optimal level. Reference voltage is set by user which is compared by servo voltage stabilizer and send signal to circuit controller for stabilizing voltage at given level. So our appliances will get voltage load at permissible level and remain safe from various electrical problems. The function of servo voltage stabilizer and static voltage stabilizer is somewhat same. The main difference is static voltage stabilizer as name suggests consists no moving parts. For controlling the voltage fluctuations, it is using electronic converter circuit. Here microprocessor of the circuit compares the fluctuation in voltage level and sends signal to generate voltage to equalize power supply. Using primary coil of buck boost transformer, this voltage is then stabilized as per required output voltage. There are some other factors given to describe difference between both stabilizers.

 Correction Speed & Time

Correction speed and time is more accurate in static voltage stabilizer because it does not have any moving parts. Its voltage corrections are more accurate using low time and providing high voltage speed for correction whereas servo stabilizer is somewhat slower than static stabilizer because it uses moving electro mechanical device.

 Reliability

Reliability of static stabilizer is mainly dependent on the IGBT power circuit whereas servo voltage stabilizer depends on the servo motors. In both the cases IGBT circuit of static stabilizer is more reliable then servo motors and that is why it is more preferred.

 Protection

If we compare both the stabilizers in terms of voltage fluctuation protection then static stabilizer provide more fast and accurate result then servo stabilizer because of the use of IGBT circuit.

 Maintenance

Servo voltage stabilizer have moving parts and it works on servo motors hence it need more maintenance then static stabilizer where other hand static stabilizer need lesser maintenance because of its static parts.

Today is the time of electronics. We are habitual of electronic and electrical appliances. We are largely dependent on them for our daily task and essential work. For working them effectively, we need constant voltage supply and also need safeguard of these valuable appliances from voltage fluctuations. Keeping in mind all this thing, Servo Voltage Stabilizer is become essential equipment. Only it can help to achieve desired performance and to overcome from voltage fluctuations. Servo voltage stabilizer has servo motor which controls the whole stabilization system to provide required stable voltage supply to your electrical appliances. Buck and boost transformers capture the voltage fluctuations of input source and regulate the current to the output. Generally servo voltage stabilizer manufacturer provide them in closed loop mechanism to maintain the voltage output regardless the voltage output.

 Many electronic appliances manufacturer suggest not installing voltage stabilizer and showing extra product feature as their product come with SMPS but reality is different from their given commitment. Some electrical and electronic appliances like refrigerators, compressors, freezers get affected by low voltage whereas recorders, lab equipments and X-ray machines can affect by high voltage. Similarly big industries which are operating their manufacturing plants 24 hour can also be affected by voltage fluctuations. Therefore the safeguard of the equipments and for continuous achieving stable voltage, we need servo stabilizers. It is chosen on the basis of voltage and load. Electricity companies provide continues constant voltage supply but at user end it will not reach constant because of heavy loading of distribution network. Here servo voltage stabilizer can save the electrical appliances by stabilizing the voltage supply. It is necessary to calculate electrical load of your premises and know how much power is required by your system. You also need to know about the power fluctuations situations at your place. After calculating all the power consumptions, you can install servo voltage stabilizer to protect your appliances from under voltage, over voltage, short circuit and overload. Similarly it is also mandatory to know usability of your Voltage Stabilizer. It is made using high quality raw material to provide necessary durability and strong built.

 They are available as per different specifications, ratings, applications and price slot. Servo voltage stabilizers are useful in various industries such as Textile, Defence, Chemical, Food, Rubber, Footwear, Lighting, Equipments, Electrical, Oil, Elevators and many more. Therefore it is necessary to know about voltage fluctuations, power consumptions and specifications of Servo Stabilizer. Before buying servo voltage stabilizer to protect your valuable equipments, you must know your load voltage requirements. It is smart idea to employ servo voltage stabilizers in your premises but one should be carefully understand its specifications and uses otherwise you cannot get maximum benefits or your important machinery get damaged. Similarly cost of servo voltage stabilizers may vary as per different specifications and requirements. Transformers and dimmer stats are important part of servo voltage stabilizer so pricing of stabilizers are largely depends on these equipments and input voltage. The cost will increase with bigger capacity of stabilizers.
