ZBW 150kva-1200kva Three-phase ac automatic Intelligent non-contact type voltage regulator with Over Current Protection
3 Phase Intelligent Non-Contact Type SCR IGBT Static Full Automatic Voltage Regulator Stabilizer
The series of three-phase fully automatic compensated voltage regulator, such as SBW, AVR, and SBW-F, can maintain the output voltage automatically and keep it stable in case of power grid fluctuation or load current change. Compared with other types of stabilizers, there are several advantages of these kinds of stabilizers: large capacity, high efficiency, no waveform distortion, good precision in regulating the voltage, suitability for all kinds of loads, the bearing ability of instantaneous overloads, and continuous long-term running. Besides, the stabilizers can smoothly shift between manual and automatic control modes. Protection functions include over-voltage, over-current, phase loss/phase sequence errors, delays, and faults. They also boast compact size, lightweight, easy installation, and reliable performance.
