Numerical Control High-Precision AC Voltage Stabilizer
Product Overview
 |
 |
The KBTW series numerically controlled high-precision AC voltage stabilizer is optimized and upgraded based on the SBW working principle. It retains the three-phase cylindrical voltage regulation structure yet breaks the traditional external compensation design. By integrating the compensation module inside copper columns, the product footprint is minimized, and the trouble of neutral wire connection at the input terminal is eliminated, albeit with higher technical complexity.

 |
This stabilizer adopts a servo drive structure with refined manufacturing details. Great breakthroughs have been achieved in the global power supply industry across system HMI, control logic, sampling circuits, protection units, multi-signal alarm functions and exterior workmanship. The product holds 1 authorized patents and has obtained CE certification.
