380V three-phase automatic compensation power regulator SBW-30KW 120KVA
Overview
The SBW series three-phase fully automatic compensated power voltage stabilizer is designed to maintain steady output voltage when the power network fluctuates or the load current varies. Distinguished by its large capacity, high efficiency, and distortion-free waveforms, this regulator offers stable voltage adjustment suitable for various loads. It can endure instantaneous overloads and operates continuously over extended periods. Additional features include seamless switching between manual and automatic control, and robust protection against over-voltage, over-current, phase failure, phase sequence errors, delays, and other potential faults. With its compact size, lightweight design, easy installation, and reliable performance, this voltage stabilizer stands out in the market.
Application
This voltage stabilizer is extensively used across diverse sectors such as post and telecommunications, department stores, elevators, hospitals, schools, printing, securities, and other
scenarios that require stable voltage to ensure smooth operations. It is essential for workshops, mines, medium-sized enterprises, and various
critical equipment, as well as computer power systems and support infrastructure.
