Product Overview

High Precision Voltage Regulation: Stabilizes fluctuating input voltage (260V–430V) to a constant 380V output
Energy Efficient: Up to 98% operating efficiency
Automatic Adjustment: Servo motor-driven regulation for fast and stable response
Comprehensive Protection: Built-in over-voltage, under-voltage, phase loss, and overload protection
Real-Time Monitoring: Digital display for three-phase voltage and current
Industrial-Grade Design: Copper construction for durability and long service life

Working Principle

The stabilizer operates using a servo motor control system. When input voltage fluctuates, the system detects the variation and automatically drives the motor to adjust the position of the carbon brush on the autotransformer.

This adjustment changes the output voltage accordingly, ensuring that it remains stable at 380V despite variations in the input supply.

Applications

This product is ideal for industrial environments where stable voltage is critical, including:CNC machines/Laser cutting machines
Automated production lines/High-power three-phase motors/Factory power distribution systems/Printing and packaging equipment

It is especially suitable for locations with unstable power grids or long-distance power transmission causing voltage drops.
