Equipped with advanced microprocessor-based control, the device offers adjustable voltage thresholds for over-voltage (OV) and under-voltage (UV) protection, enabling customization to meet specific application requirements. When voltage levels exceed the set limits, the relay automatically disconnects the load within milliseconds, preventing damage to sensitive electronics, motors, and other electrical equipment. The compact design includes terminal blocks for easy wiring and mounting options, making it suitable for both indoor and outdoor installations in residential, commercial, and industrial settings.
Dual Display Monitoring: The two high-visibility LED displays continuously show the input voltage and current, providing instant feedback on the electrical system's status. This eliminates the need for separate meters and enhances troubleshooting efficiency.
Adjustable Voltage Thresholds: Users can set custom over-voltage (240V-260V) and under-voltage (180V-220V) trip points via intuitive push-button controls, ensuring compatibility with different regions and equipment requirements. The delay time for tripping can also be adjusted to avoid false triggers during momentary fluctuations.
High-Speed Protection: The relay responds to voltage anomalies in less than 0.1 seconds, significantly faster than traditional mechanical circuit breakers. This rapid response minimizes downtime and protects equipment from even short-lived voltage spikes or drops.
Wide Current Capacity: With a 63A rating, the device can handle heavy loads such as air conditioners, pumps, industrial motors, and commercial kitchen equipment, making it versatile for various applications.
Self-Test Function: Includes a built-in diagnostic feature that periodically checks the relay's functionality and display accuracy, ensuring reliable operation over time. A fault indicator light alerts users to any malfunctions or threshold violations.
Residential Protection: Safeguards home appliances like refrigerators, TVs, and computers from voltage surges caused by lightning strikes, utility grid issues, or faulty wiring. The dual display helps homeowners monitor their electrical supply quality.
Commercial Buildings: Installed in offices, malls, and hotels to protect critical systems such as HVAC units, elevators, and IT servers. The adjustable thresholds allow customization for different equipment, ensuring uninterrupted operation in areas with unstable power supply.
Industrial Settings: Used in factories and manufacturing plants to protect motors, pumps, and machinery from voltage fluctuations that could cause downtime or expensive repairs. The high current capacity and rapid response make it suitable for heavy-duty applications.
Renewable Energy Systems: Integrates with solar or wind power setups to protect inverters and battery storage systems from over-voltage during peak generation or under-voltage during low production, ensuring stable energy distribution.
Q: Can I set different voltage thresholds for over-voltage and under-voltage?
A: Yes! The device allows independent adjustment of OV and UV trip points within the specified ranges, giving users full control over their protection settings.
Q: Is the relay compatible with 3-phase systems?
A: No, this model is designed for single-phase 230V systems. For 3-phase applications, please refer to our multi-phase protective relay models.
Q: How do I reset the relay after a voltage trip?
A: The relay will automatically reconnect the load once the voltage returns to the safe range. Alternatively, you can manually reset it using the reset button on the front panel.
Q: Can I use this device in a 110V electrical system?
A: No, this model is rated for 230V input. We offer a 110V-compatible version (model XYZ-110) for North American systems.
Q: Does the dual display show real-time or average values?
A: The displays show real-time values updated every second, providing instant feedback on voltage and current fluctuations.
