Product Overview


Product Overview

Nooyi commenced on the research of voltage regulator since 1997, we have the experience of over 20 years in the producing of voltage regulator. The ZBW-S series digital contactless AC voltage regulator is a new-generation AC regulated power supply developed and produced by this company.

ZBW voltage stabilizer is digitally designed and human-oriented, and is provided with a powerful information collection system, signal processing system and detection system as well as a perfect protection system, being widely applied in all kinds of electric environments.

Products Description

10-60kVA Non-Contact Voltage Stabilizer Specially designed for subway/railway transportation
Our voltage stabilizers have special advantages and very different from others.
(1) All new raw materials.
(2) Full (100%) capacity. 80% or less capacity is NOT recommended.
(3) State-of-the-art technology makes true energy saving.
(4) Simple installation, safe protection, reliable operation, maintenance-free.
(5) Clear, comprehensive documentation and labeling.
(6) Suitable for 3 phase imbalanced/balanced supply & imbalanced/balanced load.
(7)OVER 20 YEARS experience in producing voltage regulator
(8) Adopted New generation ARM 32-bit processor, stable and reliable, long service life.

Product characteristics:
--Bidirectional voltage compensation to solve the problem of too high and too low voltage
