Product Introduction

When voltage returns to the standard range, the device resumes power supply autonomously—no manual operation required. This seamless protection safeguards household appliances around the clock and enhances overall electrical safety for users.

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.
