Product Introduction

Once the voltage reverts to a normal scope, it restores power without the need for human interference, providing continuous protection for household appliances and improving user safety.

Product structure and performance characteristics

Voltage Monitoring: Real-time detection of voltage anomalies. If the voltage exceeds or falls below predefined thresholds (e.g., over-voltage: AC270±5V; under-voltage: AC170±5V), the protector instantly cuts off power to prevent damage to connected devices.

Auto-Reclosing Function: Automatically resumes power supply after a brief delay (e.g., 30±10 seconds) when voltage stabilizes, eliminating the need for manual resetting.

Rapid Response: Acts within ≤1 second to safeguard sensitive electronics (e.g., TVs, refrigerators) from voltage surges or drops.

Durable Design: Built with magnetically held relays and micro-processor technology for low power consumption (≤2W) and high mechanical longevity (≥100,000 cycles).

Wide Application: Ideal for single-phase AC 230V systems commonly used in homes and commercial settings, with a load capacity of up to 63A.
