Overview
HSBW series high-capacity compensation type voltage stabilizer is developed by our company according to international similar product and combined with the situation of China’s State Grid and citing foreign advanced technology. The voltage stabilizer is composed of a compensation transformer, a voltage regulating transformer, a transmission mechanism, a brush contact system, a box and a control system.
The transformer core adopts cold-rolled oriented silicon steel sheet imported from Japan, and the control system is changed from traditional analog control circuit to digital control circuit. With the functions of high voltage regulation accuracy, automatic power-on, delayed output, over/under-voltage protection, phase loss, phase misalignment, automatic protection and sound-light alarm. Easy to adjust, stable and reliable.
Application
Widely used in occasions requiring stable voltage, such as CNC machining centers, laser cutting, spring machinery, tool grinders, printing machinery, textile machinery, medical equipment, airports, shopping malls, elevators, hospitals, schools, large and medium-sized industrial and mining workshops, etc.
Product Features
