Customer Reviews
They have already used our services
We used ZHENGXI's SBW-N 100KVA three-phase automatic voltage regulator, which is very stable. Especially when the load changes greatly, the voltage is always maintained within the set range, which greatly improves the working efficiency of our equipment.
As a medium-sized manufacturing company, our previous voltage regulator always encountered overload problems, affecting production efficiency. ZHENGXI's SBW-N series three-phase automatic voltage regulator solves this problem and responds very quickly.
We attach great importance to product stability and service. ZHENGXI not only provides high-quality voltage stabilizers, but also very satisfied with its after-sales service.
The technical support is very professional and solved many problems. The transformer runs very well, no problems at all, thank them for their help!
