100Kva-2000Kva 3-phase fully automatic intelligent static voltage regulator with overcurrent protection

ZBW 3-phase fully automatic compensation voltage regulator is designed to automatically maintain the output voltage and ensure stable operation when the power grid fluctuates or the load changes. Compared with traditional voltage regulators, this series of products has significant advantages such as large capacity, high efficiency, no waveform distortion, high voltage regulation accuracy, etc. It is suitable for all types of loads, can withstand instantaneous overloads, and has the ability to operate continuously for a long time.
In addition, this static voltage regulator supports smooth switching between manual and automatic control modes, and has a full range of protection functions, including overvoltage, overcurrent, phase loss/phase sequence error, delay and fault protection. The voltage regulator is small in size, light in weight, easy to install, stable and reliable in performance, and is widely used in the industrial field.

Features:

High-quality isolation transformer: H-class insulation material is used to ensure long-term stable operation.
The input switch comes from industry-leading brands such as Chint or optional Schneider to ensure high performance and reliability.
High efficiency: The maximum efficiency can reach 99%, which effectively saves energy.
Three-phase regulation: Provide independent or subordinate three-phase regulation to meet different load requirements.
Strong overload capacity: It can withstand 200% overload within 5 seconds and 150% overload within 1 minute to ensure safe and stable operation of the equipment.
Low energy loss: Reduce power waste and improve overall efficiency.
Comprehensive protection functions: Including overvoltage protection, overcurrent protection, phase loss/phase sequence error protection, delay protection and fault protection to ensure that the equipment is protected from power fluctuations and abnormal conditions.
Manual bypass: Red copper material is used to ensure higher durability and better electrical contact.
Remote control: Remote control is achieved through RS232 or RS485 interface (optional) for easy management and monitoring.
Protection level: IP23 (NEMA 2) for indoor use, IP54 (NEMA 3R) or IP65 for outdoor use, to meet the needs of various environments.
Highly customized design: According to customer needs, flexible customization options are provided to meet the specific requirements of different scenarios and equipment.
