VJ5 digital voltage phase sequence relay is an intelligent multifunctional monitoring and protection instrument that integrates timing and counting functions with voltage display, overvoltage and undervoltage protection, phase loss protection, and phase sequence protection. It uses a powerful microprocessor chip and non-volatile storage technology, with a Chinese LCD display for intuitive display and easy operation. It can record operating parameters such as working time, working frequency, fault time, and fault frequency, display the power supply voltage in real time, and automatically cut off the power supply in case of overvoltage, undervoltage, phase loss, or phase error in the three-phase power supply, providing good protection.

VJ5 digital voltage phase sequence relay is suitable for real-time monitoring and protection of various frequently started equipment such as passenger and freight elevators, cranes, overhead cranes, and machine tools, accurately accumulating the number of equipment starts and running time. At the same time, it can monitor the power supply of the equipment, cut off the power supply in case of abnormal power supply, and record the number and cumulative time of power supply failures.
