Servo Stabilizer Three Phase
(865 products available)A three phase servo stabilizer is an automatic electromechanical device that keeps the voltage steady in a three phase power system. It delivers a constant 415 V ±1 % on each of the three lines - R, Y besides B - even when the incoming voltage swings between 300 V and 470 V or beyond. Every phase has its own small motor linked to a buck boost autotransformer. A microcontroller watches the voltage through sensing transformers and, when it drifts, sends a signal to the matching motor. The motor turns the transformer contacts plus changes the turns ratio in less than 20 ms bringing the voltage back to the target without cutting the power or distorting the waveform. The unit comes in two forms - air cooled for indoor or light duty work and oil-cooled for heavy industry. Ratings run from 10 kVA to 5000 kVA, efficiency exceeds 98 % but also built-in protection covers overload and short circuit events - a digital display shows all key data. Data centres, hospitals and lifts rely on the stabilizer to stop damage from voltage imbalance as well as to keep the load shared evenly across the three lines, in line with IS 9815.

Frequently Asked Questions about Servo Stabilizer Three Phase
What is a 3 phase servo controlled voltage stabilizer?
A 3-phase servo controlled voltage stabilizer is an automatic electromechanical device that keeps the output voltage steady for three phase electrical systems even when the input voltage changes. It is built for loads between 10 kVA and 5000 kVA. The unit guards industrial machines, data centres, hospitals plus production lines against voltage swings that would otherwise stop work, overheat windings or ruin the load. It holds the output within ±1 % of the set value. Each phase - R, Y besides B - has its own sensing transformer - a microprocessor board watches every phase in turn. It runs one servo motor per phase or one motor for a balanced system and each motor works through a buck boost transformer. The board measures input but also output voltage every cycle, compares the reading with the target (for example 415 V ±1 %), and, if the number is wrong, turns the servo motor. The motor moves the brush on an autotransformer and changes the turns ratio to raise or lower the voltage. The whole action finishes within ±20 ms. When the mains voltage rises or falls - swings of ±20 % to ±50 % are common in India - the servo rotates the variable contact as well as adds or subtracts volts without distorting the sine wave. Extra circuits rebalance unequal phases, cut the load if it exceeds the rating and let the user switch to manual bypass when needed. The stabilizer accepts up to 470 V at the input terminal or still delivers an even output. Because the servo moves the brush on a continuous winding instead of jumping between fixed taps, it reaches tighter regulation and lasts longer than relay type stabilizers, a benefit for CNC machines, motors also elevators.
What is the cost of 3 phase voltage stabilizer for home?
The price of a 3-phase voltage stabilizer built for a house in India usually sits between ₹19 500 and ₹75 000. The exact figure depends on how much load the unit can take, the brand plus extras like servo control or air- or oil cooling. If the house is small and needs only 7.5 kVA or 10 kVA to run air conditioners, pumps but also domestic appliances, the cheapest 7.5 kVA servo model opens at ₹19 500. A top tier 12 kVA Pulstron unit sells for around ₹56 500 after the discount. When capacity rises, the price rises - a 10 kVA three phase servo stabilizer retails between ₹38 700 and ₹40 600. One unit of that size suits a one- or two bedroom flat that receives three phase power as well as gives ±1 % output for inputs that swing from 340 V to 480 V. Items that push the price up are microprocessor based control boards, overload protection and well-known brands like Servokon or Bluebird. A 20 kVA model from the upper end of the market reaches ₹68 500. Those stabilizers protect appliances from the voltage swings that Indian grids often deliver. Online shops like Moglix cut the list price by 30 % to 57 %. Before purchase, match the stabilizer capacity to the total load of the house.
What is the cost of 10kVA 3phase stabilizer?
A 10 kVA three phase voltage stabiliser in India sells for between ₹18 000 and ₹42 000. The exact price depends on the brand, on whether the unit is air cooled or oil-cooled and on extras like servo control or a wide input window of 295-465 V. The least expensive models are air cooled servo units from GMDT or unbranded makers - they start at ₹18 000 plus hold the output within ±1 %, enough for a small workshop or shop. At the top of the range, Servostabilizerindia.in offers a 10 kVA three phase unit in either air or oil cooling for ₹38 700 - ₹40 635 after a discount from the list price of ₹52 000; the unit meets IS 9815. Servostabilizer.org.in advertises the same size for ₹23 000 after a similar reduction from ₹42 000. Aulten lists a three phase air-cooled servo corrector at ₹22 100, down from ₹26 300. Micron asks ₹30 900 for a model that accepts 295-465 V. Copper windings, a microprocessor based control card, built in overload protection and the length of the warranty all move the price. E-commerce sites like Moglix besides IndiaMart often shave 30-60 % off the tag but the stabiliser rating must equal the actual load.
How to select servo voltage stabilizer?
Pick a servo voltage stabiliser in four plain steps. - Work out how much power you will need. Read the nameplate of every machine or appliance and add the kilowatt figures. Divide the total by 0.8 (a normal power factor value) to turn kilowatts into kilovolt amperes. Add another quarter of the result to leave room for later growth plus for sudden surges. A 10 kW load therefore needs at least 12.5 kVA and 15 kVA is safer. Measure the voltage that reaches the building. If the mains wanders only a little, choose a unit that accepts 170 V to 270 V (single-phase). If the supply swings badly, pick 140 V to 300 V single phase or 340 V to 480 V three phase. Decide how steady the output must be. CNC machines, MRI scanners but also similar delicate gear require ±0.5 % to ±1 %; ordinary loads tolerate ±2 %. Check the rest of the specification. State whether you need single phase or three phase - demand efficiency above 98 % and a correction time below 20 ms. Choose air or oil cooling. Insist on built in protection against overload as well as short-circuit. Buy only from a supplier whose product bears the IS 9815 mark and includes a warranty lasting two to five years. Connect with the manufacturer and get familiar about exact model before you place the order.
What is the lifespan of a stabilizer?
Servo voltage stabilizers usually work for 10 - 20 years if they are kept in a normal room, protected from rain and dust. A unit that is opened once a year for a quick clean plus a bolt tightening session will, in a house or a factory, almost always pass the fifteen year mark and often reach eighteen. Heavy-duty models built by Jindal or MINGCH, wound with copper, filled with solid state transformers and fitted with control cards that have passed factory tests, still deliver steady voltage after twenty years, even when they never get a minute off in a hot steel plant. How long any one unit will run is fixed first by the way it was built but also second by what it must endure. A film of dust, steady heat above 40 °C or damp air steals up to half of the life. Forcing the stabilizer to carry more current than its plate allows wears the servo motor and the carbon brushes in months instead of years. A yearly visit from a technician who vacuums the contacts, torques the terminals as well as checks the load with a meter pushes the service life past fifteen years - skip that visit and the same stabilizer will die in the same time frame as a simple relay model - two or three years. Three-phase units installed in shops or fed with a check up every six months cool themselves better and therefore run for twelve to eighteen years. The first warnings that the end is near are lamps that flicker, a motor that hums louder than before or a delay before the voltage corrects itself. Catch those signs with a simple voltmeter also the machine can be saved before it stops completely.
What is the purpose of a servo voltage stabilizer?
Servo voltage stabilizers keep the voltage that reaches machines and appliances steady even when the mains supply rises or falls. They hold the output within half a percent to one percent of the target value. Their job is to guard delicate equipment - CNC machines, MRI besides CT scanners, lifts, air conditioners, motors, data centre racks - against drops or surges that would heat them up, make them misbehave, lose data or burn out. In countries like India, where the mains can stray by twenty to fifty percent, a small motor turns the control shaft of a buck boost transformer. A microprocessor watches the line every few milliseconds plus orders the motor to move the tap to the right spot - the sine wave stays clean and no one notices the correction. Equipment lasts roughly a third to a half longer, waste heat is cut to under two percent, stoppages are rare but also the supply meets rule IS 9815. Relay stabilizers only stay within five to ten percent - they choke on the heavy starting current of big motors and on loads that are not balanced. Servo stabilizers ride through both problems - factories, offices as well as homes that need exact voltage rely on them.
What is the price of 100 KVA 3 phase servo stabilizer in India?
The price of a 100 KVA 3-phase servo voltage stabilizer in India falls between ₹2,06,500 and ₹3,98,000. The final figure hinges on four main points - whether the unit is air cooled or oil cooled, the allowed input voltage spread (commonly 300-500 V), the brand and extras like a digital meter or a manual bypass switch. Oil-cooled versions are favoured at this size because they shed heat more effectively. Servostabilizer.org.in quotes ₹2,06,500 for a standard oil cooled model that meets IS 9815. Up-market models from Selvon Instruments or Servokon run from ₹2,38,000 to ₹3,98,000. Those units hold the output within ±1 %, withstand brief overloads plus accept a wider input window - for example 295-470 V. Purevolt India lists basic versions from about ₹1,00,000 but once the unit is tailored for balanced or unbalanced loads the price crosses ₹2 lakhs. The jump reflects thicker copper windings and a heavier duty servo motor. Cost is also pushed up by efficiency above 98 %, a response time below 20 ms and a warranty that runs from two to five years. On IndiaMart, bulk orders secure discounts of up to 20 % - plant engineers usually short list Servostar or Servokon because the brands hold up under factory conditions. Before buying, match the stabilizer's exact voltage but also current ratings to the load it must feed.
What is the price of 15KVA servo stabilizer 3 phase?
A 15 kVA three phase servo voltage stabilizer in India sells for between ₹25 200 and ₹81 900. The price hinges on two main points - the way the unit is cooled and the spread of the input voltage it must accept. Air-cooled versions sit at the lower end, ₹25 200 to ₹61 200; oil cooled versions sit at the upper end, ₹43 200 to ₹81 900. Air-cooled models are built for indoor use - their compact frames displace roughly 90 - 110 L of oil in volume. Oil-cooled models are intended for non stop industrial work - the oil bath carries heat away more effectively. Every standard unit holds the output within ±1 % of 415 V - that precision is adequate for a 12 kW motor or for a commercial shop. All units meet IS 9815. The price rises when the stabilizer must accept a wider input span (295 - 465 V), when it uses copper windings plus when it carries full overload protection. Published prices are almost always discounted 20 - 40 % - ratings are based on a 0.8 power factor load and efficiency exceeds 98 %. A firm quotation depends on the exact specification - large orders push the unit price still lower.
