Key Advantages of 3-in-1 Voltage Protectors

The 3IN1 Display Overvoltage Protector is an advanced, adjustable self-recovery device designed to safeguard electrical systems in residential, commercial, and industrial environments. By integrating voltage and current monitoring with automatic protection, it offers a complete solution for power safety.

Comprehensive Protection

This device acts as a multi-functional guardian for your electrical circuits, combining three critical safety functions into one unit:

• Over-Voltage Protection: Instantly disconnects the circuit if the voltage exceeds your set limit (e.g., due to neutral line failure), preventing burnt circuit boards and motors.
• Under-Voltage Protection: Cuts power when voltage drops too low, protecting motors in appliances like air conditioners and refrigerators from overheating and burnout.
• Over-Current Protection: Monitors the amperage and disconnects the load if the current exceeds the safe limit, preventing wire overheating and potential fire hazards.

Real-time Data & Monitoring

Unlike standard breakers, this protector features a dual-screen display that provides clear visibility into your power usage:

• Voltage Display: Shows the real-time line voltage, allowing you to detect grid instability immediately.
• Current Display: Monitors the flow of current to ensure your load remains within safe operating limits.
• Power Monitoring: The "3-in-1" capability allows you to track voltage, current, and power consumption simultaneously.

Adjustable Parameters

Every electrical load is different. The 3IN1 Display Overvoltage Protector allows for precise customization to suit your specific needs:

• Threshold Settings: You can manually adjust the over-voltage, under-voltage, and over-current values based on the rated working parameters of your equipment.
• Delay Time: The fault recovery delay time is adjustable, allowing you to set a specific wait time before power is restored to prevent short-cycling.
• Factory Reset: Supports a one-key restoration to factory settings for easy troubleshooting and reconfiguration.

Automatic Recovery

Designed to minimize downtime, the device features an intelligent self-resetting mechanism:

• Self-Recovery: Once the fault (over-voltage or over-current) is cleared and the line returns to normal, the device automatically restores power.
• Convenience: Eliminates the need for manual resetting, which is particularly useful for unattended equipment or hard-to-reach distribution boxes.

Compact Design & Easy Installation

Built for modern distribution panels, this protector is user-friendly and space-efficient:

• DIN Rail Mounting: Standard design fits easily onto 35mm DIN rails in industrial and home breaker boxes.
• Clear Indicators: Equipped with indicator lights to show the working status (On/Off/Fault) at a glance.

Improved Efficiency and Safety

By preventing electrical faults, the 3IN1 Display Overvoltage Protector extends the lifespan of your equipment and reduces maintenance costs:

• Fire Prevention: Reduces the risk of electrical fires caused by short circuits or overloaded wires.
• Equipment Longevity: Protects sensitive electronics (TVs, computers) and heavy machinery from the cumulative damage of unstable power.

Specialized Load Handling

Whether for a home or a factory, this device adapts to various scenarios:

• Residential: Ideal for protecting high-power appliances like HVAC systems, washing machines, and refrigerators.
• Commercial & Industrial: Safeguards servers, data centers, and manufacturing machinery from costly downtime caused by voltage fluctuations.

Applications

Overvoltage and undervoltage protection devices with automatic undervoltage reclosing are used in a wide variety of applications such as: industrial, commercial, residential, etc.

Industrial: In industrial environments such as manufacturing plants, processing plants and power stations. Voltage protectors maintain the performance and safety of large equipment machinery.

Commercial: For example: office buildings, retail stores and data centers require a stable power supply. 3IN1 Display Overvoltage Protector protect critical equipment such as computers, servers and HVAC systems from damage.

Residential: residential properties such as TVs, refrigerators, and air conditioners because they help protect large electronic devices and appliances in the home from voltage instability.
