A 50 kVA servo stabilizer is a three-phase voltage stabilizer rated for 50,000 VA, or about 40 kW at a 0.8 power factor. A motor-driven variac and buck-boost transformer on each phase hold the output at 410V ±1% phase to phase, and 230V ±1% phase to neutral, when the mains rises or falls. One unit protects a whole factory floor or building.
It is also called a 50 kva servo voltage stabilizer, a 50 kva 3 phase servo stabilizer or an automatic voltage regulator (AVR). Buyers also search for a 3 phase voltage stabilizer of 50 kVA or a 50 kVA servo controlled voltage stabilizer, also spelt stabiliser. The variac is a variable autotransformer, often called a dimmer, turned by a servo motor. It handles everyday voltage fluctuations without steps, giving continuous voltage stabilisation. SG Power's KNEUTRON range covers 10 to 500 kVA within its servo voltage stabilizer lineup.
The 50 kVA servo stabilizer price list in India below shows typical prices starting from about ₹85,000 + GST for a three-phase model. Air-cooled models start from about ₹85,000 and oil-cooled models from about ₹1,20,000.
| 50 kVA Model | Input Range (per phase) | Best For | Approximate Price (+ GST) |
|---|---|---|---|
| Three phase, air cooled | 170–280V | Clean, ventilated electrical rooms; offices, hospitals, malls | starts from ₹85,000 |
| Three phase, air cooled, wide range | 140–280V | Indoor sites with low voltage | Price on request |
| Three phase, oil cooled | 170–280V | Factories, dusty or hot sites, round-the-clock use | starts from ₹1,20,000 |
| Three phase, oil cooled, wide range | 140–280V | Industrial areas at the end of long supply lines | Price on request |
Prices exclude GST (servo stabilizers are generally billed at 18%), freight and installation. Prices are indicative. For the latest price, contact SG Power.
Online, 50 kVA servo stabilizer prices vary from about ₹19,000 to ₹1,90,000 or more, because sellers list very different products under the same rating. Air and oil cooling, narrow and wide input ranges, copper or aluminium windings, and prices with or without GST all appear side by side.
| Price Band (Online Listings) | What You Usually Get |
|---|---|
| Under ₹60,000 | Basic or light-duty units, narrow input ranges, or prices shown before GST and freight |
| ₹60,000 – ₹80,000 | Standard three-phase air-cooled models and entry oil-cooled models |
| ₹80,000 – ₹1,00,000 | Oil-cooled models, wider input ranges or unbalanced designs |
| Over ₹1,00,000 | Heavy-duty oil-cooled or wide-range models, single-phase 50 kVA units, and prices that include GST and delivery |
These bands describe what other sellers list online, not SG Power's own prices. Prices are indicative. For the latest price, contact SG Power.
Compare the cooling, input range, design and total delivered cost, not just the headline 50 kVA 3 phase servo stabilizer price.
Three things mainly affect the price of a 50 kVA unit: cooling, input voltage range and design. Oil cooling, the 140–280V wide range and unbalanced correction all cost more. Core and winding quality, protections, testing, GST, freight and installation explain the rest of the gap between two quotes.
Air or oil cooling: oil-cooled units need a tank and transformer oil, so they cost more
Input voltage range: the 140–280V model needs larger transformers than the 170–280V model
Winding and core: good windings and CRGO cores run cooler and last longer
Extras: data logging, password-protected settings, built-in surge protection and an automatic bypass add to the price
The 50 kVA wide-range model for low-voltage areas accepts 140–280V per phase, against 170–280V for the standard model. It suits sites where voltage often drops below 170V per phase, such as industrial areas at the end of long lines. A standard stabilizer would cut off there, while the wide-range model keeps correcting.
If your lowest voltage stays above 170V per phase, the standard model is enough and costs less.
A 50 kVA servo stabilizer can run a load of about 40 kW at full rating. For safe everyday use, keep the running load to about 32 kW, which leaves a 25% margin for the surge when motors, compressors and lifts start. Spread the load evenly across the three phases.
Add up the rated power (kW) of every machine and appliance that runs at the same time.
Divide by the power factor, usually 0.8, to convert kW to kVA.
Multiply by 1.25 to add a 25% margin for motor starting current.
Choose the next standard rating: from 41 to 50 kVA means a 50 kVA unit; above it, choose 60 kVA or more.
Sizing formula: Required kVA = (running load in kW ÷ 0.8) × 1.25
If you know the current instead: kVA ≈ 0.72 × the highest current per phase at 415V. About 70 A on the most loaded phase means 50 kVA.
Mixed single-phase and three-phase loads: add each single-phase load to the phase it is connected to, find the most heavily loaded phase, and size for three times that phase's load.
For a whole building: check the sanctioned (contract) load on your electricity bill. A mainline stabilizer is often sized at about 1.2–1.3 times the sanctioned load in kVA, then checked against the running load.
| Example Load | Running Load | Is 50 kVA Right? |
|---|---|---|
| Two or three mid-size CNC machines with a compressor | about 28–30 kW | Yes |
| Small factory: motors, lighting and fans | about 30 kW | Yes |
| Hospital or nursing home: equipment, ACs, lighting | about 28 kW | Yes |
| Apartment block: two lifts, pumps and common lighting | about 30 kW | Yes |
| Office or showroom: about 12 ACs, computers, lighting | about 25 kW | Yes |
| Running load of 33–38 kW | 33–38 kW | No, choose 60 kVA |
| Running load of 40 kW or more | 40 kW and above | No, choose 75 kVA or more |

At 50 kVA, SG Power offers both an air-cooled and an oil-cooled servo stabilizer; 50 kVA is the largest air-cooled size in its range. Choose a 50 kva air cooled servo stabilizer for a clean, ventilated electrical room. Choose a 50 kva oil cooled servo stabilizer for dusty, hot or round-the-clock industrial sites.
| 50 kVA Air Cooled | 50 kVA Oil Cooled | |
|---|---|---|
| Cooling | Natural or fan air flow | Transformer immersed in oil |
| Best site | Clean, dry, ventilated indoor rooms; hospitals, offices, malls | Dusty, humid or hot sites; heavy industrial loads |
| Duty | Continuous, in a cool room | Continuous, including 24×7 operation |
| Maintenance | Dust cleaning, brush checks | Also oil level and condition checks |
| Weight and size | Lighter, more compact | Heavier, needs a firm base |
The 50 kVA air cooled servo stabilizer price starts from about ₹85,000 + GST, and the oil-cooled price from about ₹1,20,000 + GST, depending on the input range.
A balanced 50 kVA servo stabilizer corrects all three phases together, which suits three-phase motors and machines that load each phase equally. An unbalanced model corrects each phase on its own, which suits buildings where each phase feeds different single-phase loads, such as ACs, lighting and computers.
| Balanced | Unbalanced | |
|---|---|---|
| How it corrects | All phases together | Each phase separately |
| Best for | CNC machines, motors, pumps, compressors | Hospitals, offices, malls, apartments |
SG Power makes both the balanced and the unbalanced 50 kVA servo stabilizer. One cabinet with three per-phase sections usually costs less and takes less space than three separate single-phase units. If you're unsure, share your load list and supply readings, and we'll recommend one.
The 50 kVA servo stabilizer specifications below cover SG Power's four three-phase, four-wire models: air or oil cooled, each with a standard or wide input range. All hold 410V ±1% phase to phase at 97% efficiency, tested as per IS 2026 (Part 1):1977, with an output delay adjustable from 3 to 200 seconds.
| Parameter | Specification |
|---|---|
| Capacity | 50 kVA, three phase, four wire |
| Input voltage range | 170–280V or 140–280V per phase (340–480V phase to phase on the standard model) |
| Output voltage | 410V ±1% (P-P), 230V ±1% (P-N); settable to 380, 400 or 415V |
| Regulation | ±1% |
| Efficiency | 97%, tested as per IS 2026 (Part 1):1977 |
| Output frequency | 50 Hz ±3% |
| Output delay | 3–200 seconds, adjustable |
| Control | KNEUTRON microcontroller, true RMS sensing |
| Motor | High-torque AC stepper motor |
| Winding | Pure copper winding |
| Housing and mounting | Powder coated CRC sheet, floor mounted |
| Transformer | In-house CRGO core, built to IS 9815 (Part 1), IS 5142 and IS 2026 |
| Design | Balanced or unbalanced |
| Duty | 100% load, continuous |
These are the Guaranteed Technical Particulars from SG Power's own datasheets for the four models. Other input ranges are built to customer specification, and the IS standards are published by the Bureau of Indian Standards. Sellers state the input range either per phase or phase to phase; phase-to-phase voltage is about 1.73 times the per-phase voltage, so convert both to the same basis before comparing quotes.
Key features of every SG Power 50 kVA unit are a KNEUTRON digital controller, a front-panel display and ±1% voltage regulation. Its protections cut off the output on over-voltage, under-voltage, overload, phase reversal and single phasing, and add an adjustable trip time delay. Calibration is done on a touch-pad.
The display shows: phase-to-neutral and phase-to-phase voltages, frequency and the current of each phase. You can set the output voltage and the input voltage band, and choose manual or automatic start and stop. True RMS sensing works without a separate control transformer.
| Protection | What It Guards Against |
|---|---|
| Over-voltage cut-off | High mains voltage reaching machines and equipment |
| Under-voltage cut-off | Very low voltage that overheats motors |
| Overload cut-off | Load above the set limit; the display shows “Overload”, and the output restarts once the load is reduced and Start is pressed |
| Trip time delay (3–200 seconds) | Compressor and motor damage when power returns after a cut |
| Phase reversal cut-off | Wrong phase sequence that can run motors and lifts backwards |
| Single phasing protection | Loss of one phase, which can burn out three-phase motors |
A 50 kVA servo stabilizer is used where a three-phase running load of about 25 to 32 kW needs steady voltage. Typical users are small factories, CNC shops, hospitals, hotels, malls, cold storage units and apartment blocks. One mainline unit protects every machine and appliance on the supply.
50 kva servo stabilizer for factory use: an industrial servo stabilizer for motors, compressors, injection moulding, printing and packaging lines
50 kva servo stabilizer for CNC machines: two or three mid-size CNC lathes or VMCs on one supply; for drives with heavy harmonics, ask about a K-rated isolation transformer
Hotels, malls, showrooms and institutions: ACs, lifts, kitchen equipment and lighting, usually with an unbalanced model
Cold storage and water bottling plants: compressors, filling lines and pumps that run for long hours
50 kVA servo stabilizer for lift and apartment use: housing societies with lifts, water pumps and common-area lighting
SCADA-based and automated systems: controllers and drives that need good power quality and steady voltage
50 kva servo stabilizer for hospital: hospitals, nursing homes and diagnostic centres; pair with an isolation transformer for sensitive medical equipment
The main advantages of a 50 kVA servo stabilizer are a precise, steady output, no distortion to the voltage waveform and the ability to carry full load continuously. Its limitations are carbon brush wear, slower correction than a static stabilizer, and no electrical isolation, so sudden spikes still need a surge protection device.
| Advantages | Limitations |
|---|---|
| ±1% output on SG Power models, smooth and stepless | Carbon brush and variac track wear, so yearly service is needed |
| Handles full load continuously, including motors and lifts | Corrects more gradually than a static (solid-state) stabilizer |
| Adds no waveform distortion | No galvanic isolation; add a surge device, or an isolation transformer for sensitive loads |
For most 50 kVA three-phase sites, a dimmer-type servo stabilizer with unbalanced, per-phase correction gives the best value. A linear servo type suits buyers who want a different variac design at a higher price. A static (IGBT) stabilizer gives the fastest voltage correction with no moving parts, but costs the most.
| Dimmer-Type Servo | Linear Servo | Static (IGBT) | |
|---|---|---|---|
| How it corrects | Motor turns a carbon brush on a toroidal variac (dimmer) | Contacts move along a straight variac winding | Solid-state switching, no moving parts |
| Output | Smooth, stepless, no added distortion | Smooth, stepless | Fast and tight; check its harmonic performance |
| Upkeep | Yearly brush and variac checks | Contact and track checks | Electronics; repairs need specialist parts |
| Price at 50 kVA | Moderate | Higher | Highest |
| Best for | Factories, hospitals, buildings with unbalanced loads | Buyers who prefer a linear design | Very fast-changing loads where budget allows |
SG Power's KNEUTRON 50 kVA models use the dimmer-type design with a buck-boost transformer, and SG Power also makes linear servo voltage stabilizers.
Running machines that can't afford voltage trips? Tell us what is on the supply and we will size the unit for it.
To choose between 50 kVA servo stabilizer manufacturers and suppliers, first check that the unit suits your load, phase balance and your site's lowest voltage. Then compare cooling, regulation, protections, in-house manufacturing, testing and local service. Ask each seller these ten questions:
Do you manufacture the stabilizer, or resell another company’s unit?
Is it air or oil cooled, and balanced or unbalanced? (For harsh sites, also ask about the enclosure’s protection against dust and moisture.)
What input range does it cover per phase? (Record your lowest voltage over a few days first.)
What output regulation, efficiency, correction speed (volts per second) and short-term overload capacity does it have? (SG Power: ±1%, 97%)
Is the winding copper or aluminium, and are the transformers made in-house?
Does it include over/under voltage, overload, phase reversal, single phasing and time delay protection, and what happens to the healthy phases if one phase fails?
Was the unit tested before dispatch, and is there a test report and user manual? (SG Power: 173 checkpoints, NABL lab-tested design)
Are GST, freight, installation, a manual or automatic bypass switch and the first oil fill (on oil-cooled units) included?
Who services it near my site, and are carbon brushes and control cards available locally?
What warranty and AMC (annual maintenance contract) are offered, in writing?
Before ordering, share your load list, supply type and voltage readings with the 50 kVA servo stabilizer manufacturer. With these details, the manufacturer can confirm whether 50 kVA is right and choose the cooling, design and input range. Accurate details also give you a firm quote that won't change after a site visit.
Load list: each machine’s rating, and which ones run together
Supply: whether a DG set also feeds the load, and its rating
Voltage readings: the lowest and highest voltage on each phase over a few days, including peak hours
Site conditions: indoor or outdoor, dust, heat, moisture and the space available
Output and wiring: the output voltage you need (380, 400 or 415V) and where the unit will be installed
A manufacturer designs, builds and tests the 50 kVA servo stabilizer, while a supplier or dealer resells units bought from a manufacturer. Buying from the manufacturer usually gives factory pricing, custom input ranges and direct technical support. A local supplier can help with fast stock delivery, as long as the manufacturer backs the service.
SG Power is both a manufacturer and a direct supplier: every unit is manufactured in its own factory and supplied directly. It also works with contractors, consultants and project buyers who need several units.
For 50 kVA servo stabilizer installation, have a qualified electrician fit the unit on the mainline after the meter or DG changeover. Use cables sized for about 70 A per phase and proper earthing. Follow the CEA safety and electric supply regulations. Maintenance is simple: keep it clean and book a yearly service.
Place the unit on a firm, level floor in a dry, ventilated room near the main LT panel, and never box or cover it. Air-cooled 50 kVA units listed online measure about 850 × 520 × 770 mm, and oil-cooled units are larger
Connect the stabilizer’s body earth terminal to the building’s earthing system
Servo units hum while correcting, so place the unit near the distribution board, away from wards, offices and bedrooms
If an online UPS serves critical loads, connect the stabilizer first and the UPS after it, so the UPS charges from steady voltage
Check the phase sequence at installation, and connect the neutral properly
Use the bypass switch only during servicing; machines are unprotected in bypass
Fit a surge protection device ahead of the stabilizer; a servo unit corrects slow voltage changes, not lightning spikes, and lightning is a common cause of stabilizer failure.
Check your earthing too. SG Power also makes earthing rods, chemical earthing electrodes, earth pit covers and lightning protection systems.
| Task | How Often | Who |
|---|---|---|
| Dust the body and vents | Monthly | User |
| Check input and output readings on each phase | Weekly | User |
| Inspect and replace worn carbon brushes | Yearly, or if correction slows | Trained technician |
| Oil-cooled units: check oil level every 3 months; test and top up with transformer oil to IS 335 yearly | 3–12 months | Trained technician |
| Full service and calibration | Yearly or under AMC | SG Power service |
Wrong sizing: running near full load overheats it, while a very light load can make the servo “hunt” back and forth
Supply beyond its range: frequent swings outside the input range keep the motor and brush moving all day
Heat and dust: a hot, dusty or badly ventilated room speeds up insulation ageing and brush wear
Skipped maintenance: worn brushes and loose terminals cause sparking and early failure
