Industrial 3 Phase Servo Stabilizers
Heavy-duty voltage regulation from 10 KVA to 2000 KVA. Designed for CNC machines, manufacturing plants, and continuous industrial operations.
Why Industries Trust ServoKai 3-Phase Stabilizers
Industrial machinery requires a perfectly balanced three-phase supply. Even a minor voltage imbalance across phases can cause motors to overheat, CNC machines to malfunction, and drives to fail.
Our 3 Phase Servo Stabilizers correct each phase independently, ensuring a precise 415V (±1%) output regardless of input fluctuations. Built with premium CRGO cores and high-grade copper/aluminum winding, they are engineered for 24/7 continuous duty.
- Independent Phase Correction
- High Efficiency > 98%
- Withstands Heavy Inrush Currents
- Customizable Input Voltage Windows

Frequently Asked Questions
What is a 3 Phase Servo Stabilizer?
A 3 Phase Servo Stabilizer is an automatic voltage regulation device used to maintain a stable, constant voltage across three electrical phases. It uses a servo motor mechanism to correct voltage fluctuations instantly, preventing damage to sensitive and heavy industrial machinery.
Should I choose Oil-Cooled or Air-Cooled for 3 Phase?
Air-cooled stabilizers (up to 40-50 KVA) are compact and ideal for indoor, clean environments like commercial buildings or IT labs. Oil-cooled stabilizers (up to 2000 KVA) use transformer oil for superior heat dissipation, making them necessary for heavy manufacturing, outdoor installations, and dusty environments.
What is the price of a 3 Phase Servo Stabilizer?
The price depends on the KVA rating, cooling type, and specific voltage input window required. Since we are a direct manufacturer, ServoKai offers highly competitive factory-direct pricing. Contact us with your load requirements for an exact quotation.
What protection features are included?
Our 3 phase stabilizers come with phase-to-phase high & low voltage cut-off, single phase preventer, short-circuit protection, time delay systems, and an emergency bypass switch.
