Sequence Failure Three Phase Voltage Monitoring Relay JVR800-1 For Refrigeratin

Sequence Failure Three Phase Voltage Monitoring Relay JVR800-1 For Refrigeratin

This product is a kind of intelligent multi-function monitoring and protection instrument, which integrates the functions of the timer and voltage display, over voltage and under voltage protection, phase loss protection and phase sequence protection. It adopts powerful microprocessor chip and non-volatile memory technology. , Chinese LCD display, intuitive and easy to operate. It can record operating parameters such as working time, number of failures, failure times, etc., real-time display of the power supply voltage, and automatically cuts off the power supply when overvoltage, undervoltage, phase loss, and fault of the three-phase power supply occur.
It is suitable for real-time monitoring and protection of central air conditioners, cranes, refrigeration equipment, compressors, distribution boxes, lifts, various passenger and cargo lifts, cranes, cranes, and machine tools, etc., and accumulates the number of equipment startups and running time. At the same time, the power supply of the device can be monitored, and when the power supply is abnormal, the power supply is cut off, and the number and cumulative time of the power supply failures are recorded.

Dimensions: 80H×40W×54D
caveat! This product is generally the power supply side of the three-phase power supply sampling, shall not be installed in the output side of the inverter current!

Alarm function
When the power supply is over-voltage, phase-missing or error-free, the LCD flashes the words “overvoltage”, “undervoltage”, “phase loss”, and “phase error”, and the relay output contacts are disconnected. Accumulated faults and faults can be accumulated.

1. The relay output is closed when the meter is working properly, and it is disconnected when the meter loses power or is in a fault protection state.
2. The counting signal is voltage signal, the voltage grade is divided into: DC/AC24V, DC/AC110V, DC/AC220V (for other voltages can be customized), AC and DC can be, if it is DC voltage should pay attention to the positive and negative polarity.

Features:

• Mircroprocessor technolony provides highly accurate and repeatable protection
• Built-in LCD and keypad afford a precise digital setting
• Compact modular 43mm housing
• Adjustable over-and unervoltage ,voltage hysteresis
