The SGAVR-150KVA is a 3-phase automatic voltage stabilizer and transformer integrated machine designed to convert 380V input to stable 220V output while regulating voltage fluctuations within ±1%–2% accuracy. With a ±15% input voltage compensation range, ≥98% efficiency and comprehensive protection functions, it provides reliable power conditioning for CNC machines, medical equipment, data centers and other sensitive industrial loads.
The SGAVR-150KVA combines automatic voltage stabilization and step-down voltage transformation in one integrated unit. It accepts a 3-phase 4-wire 380V AC input and provides a stable 3-phase 4-wire 220V AC output, making it suitable for equipment that requires both voltage conversion and precise voltage regulation.
The stabilizer uses a dual CD-type silicon-steel core ferromagnetic resonance circuit to compensate for input voltage fluctuations. Within the standard ±15% input voltage range, the system maintains an output voltage regulation accuracy of ±1%–2%.

The SGAVR integrated stabilizer and transformer is designed for industrial and commercial applications where both voltage stabilization and voltage conversion are required.
The product is particularly suitable for applications where unstable input voltage or an incorrect voltage level could affect equipment performance, measurement accuracy or operational reliability.
The SGAVR combines three technologies:
1. Ferromagnetic Resonance Voltage Stabilization
The stabilizer uses a dual-core magnetic circuit to continuously compensate for input voltage fluctuations.
2. Electromagnetic Voltage Transformation
The transformer section uses electromagnetic induction and the winding turns ratio to step down the stabilized voltage from 380V to 220V.
3. Microcomputer Intelligent Control
The control system monitors voltage and load conditions in real time and automatically manages the voltage regulation process and protection functions.
Compared with installing a separate voltage stabilizer and transformer, the integrated SGAVR solution provides:
