16A Metering Socket 220V Overvoltage Undervoltage Protector

16A Multifunctional Metering Socket with Large Screen Display — 220V Voltage & Current Protector

Keep your household appliances safe from electrical fluctuations with this 16A Multifunctional Metering Socket. Featuring a large LED screen that displays real-time voltage and current values, this smart protective socket automatically monitors your circuit and cuts power whenever unsafe voltage or current levels are detected — then reconnects automatically once conditions return to normal. It's the simple, plug-in solution for safeguarding your home electronics.

Key Features

• Large LED Display: Three-digit LED screen clearly shows live voltage and current readings — doubles as a built-in voltmeter and ammeter for easy monitoring.
• Automatic Cut-Off & Reconnect: Instantly disconnects power during overvoltage, undervoltage, or overcurrent events, and automatically restores power once the circuit stabilises.
• Fully Adjustable Protection Ranges: Set your overvoltage threshold (230V–300V), undervoltage threshold (140V–210V), overcurrent limit (1–16A), and reconnect delay time (1–500 seconds) to suit your specific needs.
• Plug-In Convenience: No tools or complex wiring required — simply plug in and it's ready to protect your appliances.
• Durable ABS Construction: Made from high-quality ABS material with high hardness, wear resistance, and high pressure resistance for long-lasting, reliable performance.
• Wide Compatibility: Rated 220V–240V, 50/60Hz — suitable for a broad range of household appliances and electronic devices.

Frequently Asked Questions

Q: What does the 16A metering socket protect against?

A: This multifunctional metering socket protects connected appliances against three common electrical hazards: overvoltage (voltage exceeding your set threshold between 230V–300V), undervoltage (voltage dropping below your set threshold between 140V–210V), and overcurrent (current exceeding your set limit between 1–16A). When any of these conditions are detected, the socket automatically cuts power to prevent equipment damage.

Q: How do I set the protection thresholds on this socket?

A: The overvoltage, undervoltage, overcurrent, and delay time values are all user-adjustable directly on the device. You can fine-tune the overvoltage cutoff (230V–300V), undervoltage cutoff (140V–210V), maximum current (1–16A), and the reconnection delay (1–500 seconds) to match the specific requirements of your appliances.

Q: Will the socket restore power automatically after a fault?

A: Yes. Once the socket detects that the voltage and current have returned to safe, normal operating levels, it will automatically reconnect the power supply after the programmed delay time has elapsed. This means you don't need to manually reset the socket after every electrical fluctuation event.

Q: Is this socket compatible with standard household appliances?

A: This socket is rated for 220V–240V at 50/60Hz and supports a load current of up to 16A, making it compatible with a wide variety of standard household appliances, including refrigerators, washing machines, televisions, and air conditioners commonly used on 220V–240V electrical systems.

Q: Can I use this socket as a voltmeter or ammeter?

A: Absolutely. The built-in three-digit LED display shows real-time voltage and current readings at all times, effectively functioning as a combined voltmeter and ammeter. This makes it easy to monitor your circuit conditions at a glance without needing separate measuring instruments.
