Overview
"Shake" is a common name for voltage sag/sudden. It generally refers to a power quality event where the rms voltage drops to 10% to 90% of the rated value and the typical duration is 10ms to 600ms.
Severe voltage sag, will use electrical equipment to stop working, or cause the quality of the products produced to decline. The severity of the voltage dip impact varies with the characteristics of the electrical equipment used.
For industries with high requirements for continuity, the danger of “shaking electricity” is enormous, and these hazards are particularly evident in low-voltage (0.4kV) systems with more industrial process equipment. Therefore, the "anti-shake" of the low-voltage system has become an urgent problem to be solved.

The company's "anti-shake module" uses today's advanced power electronics technology, computer technology and automatic control technology, mainly used in low-voltage systems to overcome the abnormal tripping of contactors in the low-voltage system.


Characteristics
1. Energy saving: This module has obvious energy saving effect (the contactor consumes at least 80% of power consumption).
2. Eliminate overvoltage and increase the service life of the contactor.
3. Eliminate the working noise of the contactor.
4. The application mode is flexible and can be selectively blocked; the contactor current can be set on site.
5, support restart function.
6, with communication capabilities.

7. Simple wiring and convenient installation.
