In-Depth Review TG4G Review ·2026-06-26 · For reference only

What is it

This is the official website of sz-beit.com (Shenzhen Beitong Control Technology Co., Ltd.), a Chinese high-tech enterprise focusing on anti-voltage-sag power control equipment. Its core product is the self-developed DZQ series motor restart controller, which mainly solves the problem of abnormal shutdown of industrial motors caused by instantaneous voltage loss and voltage sag in the power grid, to ensure continuous production.

Core Features & Positioning

The website clearly organizes voltage sag issues for different application scenarios and offers a product line covering all working conditions:

  • For instantaneous voltage loss caused by adjacent line faults within 200ms, it provides contactor auxiliary hold products
  • For scenarios where voltage loss exceeds 1 second, such as power switching and reclosing, it offers a batch self-starting scheme to avoid grid impact caused by simultaneous startup of large-capacity motors
  • It also offers dedicated anti-voltage-sag products adapted for inverters, soft starters and DCS interlock circuits

Technically, it adopts a hardwired logic design, with faster response speed than traditional microprocessor solutions, and can handle most short-duration voltage sag faults that conventional equipment cannot detect.

Pros & Cons Summary

Advantages: High product specialization, more than 10 years of focused development on voltage sag issues, strong technical adaptability, and the product has been verified in application by multiple leading domestic petrochemical and petroleum enterprises, with guaranteed reliability.
Disadvantages: The website is outdated with incomplete information display, no public pricing, missing content in the download section, and it is not convenient for users to obtain information.

Who It's For & Accessibility

This product is suitable for industrial enterprise users with high requirements for production continuity, such as petrochemical, chemical, metallurgy, and power generation industries. The website is hosted on a domestic Chinese server, can be accessed directly and normally in mainland China, and has a full Chinese interface.
