Intro：The KB SBW and KBDBW series AC compensating voltage stabilizers (hereinafter referred to as stabilizers) are power products developed and designed by our company in response to the current situation of China's national power grid. They can automatically maintain a stable output voltage when fluctuations in the external power supply network or changes in the load cause voltage fluctuations.
Product Details:
Product Overview
The KB SBW and KBDBW series AC compensation voltage stabilizers (hereinafter referred to as stabilizers) are power supply products developed and designed by our company in response to the current national power grid conditions in China. They can automatically maintain stable output voltage when voltage fluctuations occur due to external power supply network changes or load variations. Compared with other types of stabilizers, this series of products has advantages such as large capacity, high efficiency, no waveform distortion, and smooth voltage regulation. They are suitable for a wide range of loads, can withstand instantaneous overload, can operate continuously for long periods, support manual/automatic switching, and are equipped with overvoltage protection, phase loss, phase sequence protection, and automatic mechanical fault protection. The machines are reliable, compact, lightweight, and easy to install and use.
