Product Description

The SBW Series Three-Phase Automatic Compensation Voltage Stabilizer is designed by our company based on the conditions of the power grid in China, integrating and absorbing foreign technologies to stabilize AC voltage. When voltage fluctuations occur due to changes in the external power supply network or load variations, the stabilizer can automatically maintain a stable output voltage.

Compared with other types of voltage stabilizers, the SBW Series offers advantages such as large capacity, high efficiency, no waveform distortion, and smooth voltage regulation. The SBW high-power stabilizer is suitable for a wide range of loads and can withstand instantaneous overloads. It is capable of long-term continuous operation, with manual/automatic switching available at will. The stabilizer is equipped with over-voltage protection, phase loss and phase sequence protection, as well as automatic protection against mechanical faults. In addition, it features compact size, lightweight, easy installation, and reliable operation.

The SBW high-power stabilizer can be widely applied in various fields such as industry, agriculture, transportation, postal and telecommunications, military, railways, scientific research, and cultural sectors. It is suitable for large electromechanical equipment, metal processing machinery, production lines, construction machinery, elevators, medical devices, embroidery and textile machinery, air conditioning systems, broadcasting and television equipment, household appliances, lighting, and other applications requiring stable voltage.

	Three-phase Voltage Unbalance	Increment ≤0.5%
Protection	Over-voltage	When the output line voltage exceeds the set value by 10%, an alarm is triggered and the output is cut off after a 6-second delay. (Overvoltage threshold and delay time can be customized according to user requirements)
	Under-voltage	When the output line voltage drops below the set value by 12%, an alarm is triggered and the output is cut off after a 12-second delay. (Undervoltage threshold and delay time can be customized according to user requirements)
	Overload	Dual Protection: Electronic detection + circuit breaker (fixed by model, non-adjustable) Overload Protection: For sustained overload above rated load, output is cut off following inverse time characteristic.
	Over-current	Dual Protection: Electronic detection + circuit breaker (adjustable per model and approval) Overload Protection: Output cut off after 20 s short delay if current >1.2× rated, following inverse time characteristic.
	Short-circuit	Instantly cuts off the output in the event of a fault.
	Bypass	Ensures continuous power supply during stabilizer fault or maintenance.
