Industrial Three-Phase Voltage Regulator for 30K~2000kVA Power Supply Efficiency
Overview
The SBW series three-phase full automatic compensated power voltage stabilizer is essential for environments where power network fluctuations or load variations occur. This stabilizer ensures a steady output voltage automatically. Compared to other voltage stabilizers, it boasts large capacity, high efficiency, no wave distortion, and stable voltage adjustment. It is adaptable to various loads, capable of handling instantaneous overloads, and can operate continuously for extended periods. Notably, it allows seamless transition between manual and automatic control. The stabilizer is outfitted with protections against over-voltage, over-current, phase failure, phase sequence errors, delays, and more. Additional benefits include its compact size, lightweight design, easy installation, and reliable performance.
Application
This voltage stabilizer is extensively used across various sectors including post and telecommunications, department stores, elevators, hospitals, schools, printing, securities, and more.
It ensures a stable voltage supply for essential operations in workshops, mines, medium enterprises, and other critical environments.
It is particularly vital for important equipment and computer power systems.
