The SBW series three-phase fully automatic compensated power voltage regulator is suitable for applications where voltage fluctuations are caused by variations in the external power grid voltage or load changes. It automatically maintains a stable output voltage. Compared with other types of voltage regulators, this series offers advantages such as large capacity, high efficiency, no waveform distortion, and smooth voltage regulation. It is suitable for a wide range of loads, can withstand instantaneous overload, and can operate continuously for long periods. It supports manual/automatic switching and is equipped with overvoltage protection, phase loss protection, phase sequence protection, and automatic protection against mechanical failures. In addition, the unit features a compact size, light weight, easy installation, and reliable operation.

▌Voltage Stabilizer Functions Features:
▌Protection Function:
☑Overload Protection:
When the load power reaches 120%, the voltage stabilizer automatically activates protection, cutting off the output.
☑Overvoltage Protection:
When the output phase voltage exceeds 250V, the overvoltage indicator lights up, and the output is automatically cut off.
☑Undervoltage Protection:
When the output voltage drops below 184V, the undervoltage indicator lights up, and the output is automatically cut off.
☑Delay Protection:
Upon power-up, a delay of several seconds is automatically initiated before voltage stabilization begins.
☑Short Circuit Protection:
When a short circuit occurs, the voltage stabilizer automatically stops output and requires manual reset to restore output.
☑Over temperature protection:
Over-temperature protection will shut down the regulator if it exceeds a safe operating temperature, preventing damage to its internal circuitry.
▌Product Characteristics:
Effective energy saving via 3 copper core voltage regulating columns & 3 high-power voltage stabilizing compensation coils.
Dual microcomputer control board, one-key switching of the main control board, quickly resolving faults.
Manual/automatic conversion key, easily switching between manual and automatic output modes.
Mains/stabilized flexible voltage switch providing mains direct and stabilized dual-mode functions.
Electric operating mechanism combined with 1017 carbon brushes, achieving precise and stable output voltage.
Adopts high-quality silver point AC contactor, energy-saving and noise-free, long-lasting and reliable.
▌Application:
Our SBW voltage regulator can be widely used in: industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, posts and telecommunications, hotels, scientific research and other departments of electronic computers, precision machine tools, computed tomography (CT), precision instruments, test equipment, elevator lighting, imported equipment and production lines and other places that need stable voltage power supply. It is also suitable for users at the end of the low-voltage distribution network where the power supply voltage is too low or too high, and the fluctuation range is large, and the electrical equipment with large load changes, especially for all the places where the power grid waveform is required to be high. High power compensation type power regulator can be connected to fire, hydraulic, small generators.
