250 KVA Servo Stabilizer
250 KVA Servo Stabilizer Manufacturer in India
The 250 KVA Servo Stabilizer is a three phase servo voltage stabilizer that holds your output at a precise 415V/230V ±1%, however wide the incoming supply swings. Servo Stabilizer India builds every 250 KVA unit to order — oil-immersed for 100% continuous loading and harsh ambient conditions — and supplies it factory-direct across India with installation and AMC. It is sized for heavy industrial plant — furnaces, rolling mills and full-factory main lines.

How to size a 250 KVA servo stabilizer
A 250 kva servo stabilizer is rated to deliver 250 KVA at the output. As a rule we keep 20–25% headroom above your connected load, so a 250 KVA unit is the right choice for a working load of around 200 kW. That margin absorbs the starting surge of motors, compressors and pumps without the stabilizer running hot or tripping. If your load includes several large motors that start together, send us the list — we'll confirm whether 250 KVA is enough or whether to step up to the 300 kva servo stabilizer.
At 250 KVA the oil-immersed for 100% continuous loading and harsh ambient conditions. It is supplied as a three phase 415V unit with independent phase control, so it corrects each phase separately even when the incoming supply is unbalanced. Read our KVA sizing guide or air vs oil cooled comparison for more detail.
