Product Overview
The KBZ series intelligent contactless compensation AC voltage stabilizer is a new generation of fast voltage stabilizing equipment successfully developed based on our company's many years of experience in producing compensation-type power voltage stabilizers. It utilizes innovative 32-bit computing and measurement chip control technology, fast true RMS voltage sampling technology, current zero-crossing switching technology, and rapid compensation voltage stabilization technology. It integrates intelligent metering, rapid voltage stabilization, and fault diagnosis, making the product safe, efficient, and precise. The product mainly consists of an isolation transformer, SCR module, CPU control core, rapid voltage stabilization technology, and safety protection devices. It achieves full contactless control, ensuring safety, efficiency, energy saving, and environmental protection, perfectly combining SCR switching technology and transformer technology.
The product is widely used in industrial, transportation, postal, defense, railway, and scientific research fields, for large electromechanical equipment, metal processing equipment, production lines, elevators, medical devices, embroidery and textile devices, air conditioners, radio and television equipment, household appliances, and building lighting, where stable voltage is required.
Human-Machine Interface
The KBZ series intelligent contactless compensation AC voltage stabilizer features a large LCD display. Through the LCD screen, parameters such as voltage, current, fault status, and operating mode can be intuitively displayed. Its voltage stabilization accuracy, output voltage, and operating mode can be set via the panel, making operation simple.

Working Principle
The KBZ series intelligent contactless AC voltage stabilizer utilizes microcomputer (MCU PLD 12-bit high-speed AD) intelligent detection. It sends output commands to control the rapid switching of electronic modules (IGBT or SCR), and maintains stable output voltage through the principle of same-frequency transformer, phase locking, and sine wave superposition compensation.
