One of the most common questions buyers ask before purchasing a servo voltage stabilizer is: how much does it cost? The answer depends on capacity (kVA), phase type (single or three phase), cooling method (air or oil cooled), and features. This guide gives you a realistic price framework so you can budget correctly.
What Factors Affect Servo Stabilizer Price?
graph LR Price["💰 Final Price"] --> Cap["Capacity (kVA) Biggest factor"] Price --> Phase["Phase Type 3ph costs more than 1ph"] Price --> Cool["Cooling Method Oil > Air cooled"] Price --> Range["Input Voltage Range Wider range = more copper"] Price --> Feat["Protection Features Display, bypass, MCB"] Price --> Source["Supply Source Direct > Distributor"]
- Capacity (kVA) — The biggest driver. Higher kVA = higher cost due to more copper, core material, and larger enclosures.
- Phase Type — Three phase units cost more than single phase at the same kVA due to 3× the electrical components.
- Cooling Method — Oil cooled units cost more than air cooled due to the transformer oil and sealed tank construction.
- Input Voltage Range — Wider input range requires more variac copper and increases cost.
- Brand & Origin — Factory-direct from a manufacturer like ServoKai is always cheaper than buying through distributors.
Servo Stabilizer Price Range by Capacity
| Capacity | Type | Approx. Price Range (INR) |
|---|---|---|
| 5 kVA | Single Phase, Air Cooled | ₹8,000 – ₹14,000 |
| 10 kVA | Single Phase, Air Cooled | ₹14,000 – ₹22,000 |
| 20 kVA | Single Phase, Oil Cooled | ₹22,000 – ₹35,000 |
| 30 kVA | Three Phase, Air Cooled | ₹35,000 – ₹55,000 |
| 50 kVA | Three Phase, Oil Cooled | ₹55,000 – ₹85,000 |
| 100 kVA | Three Phase, Oil Cooled | ₹1,10,000 – ₹1,60,000 |
| 200 kVA | Three Phase, Oil Cooled | ₹2,20,000 – ₹3,20,000 |
| 500 kVA | Three Phase, Oil Cooled | ₹5,50,000 – ₹8,00,000 |
| 1000 kVA | Three Phase, Oil Cooled | ₹11,00,000 – ₹16,00,000 |

Why Buy Factory-Direct from ServoKai?
When you purchase through a dealer or reseller, you typically pay 20–35% more due to margins and logistics. ServoKai System is a direct manufacturer based in Delhi:
- No distributor margins — you pay the factory price
- Full customization at no extra cost (input range, enclosure, protection features)
- 1-year manufacturer warranty with direct service
- Fast delivery across Delhi NCR; pan-India shipping available
How to Calculate the Right Capacity (and Save Money)
Oversizing a stabilizer wastes money. Undersizing causes overload failure. To calculate correctly:
- List all your connected loads and their power ratings in Watts or kVA.
- Add a 25% safety margin for motor startup surges and future expansion.
- For motors and inductive loads: multiply the kW rating by 1.5 to get the effective kVA demand.
Example: A factory with 30 kW of mixed loads needs: 30 × 1.25 = 37.5 kVA → Round up to a 40 kVA three phase stabilizer.
