3 Phase 4 Wire Automatic Transfer Switch 63A Changeover Switch Voltage Protector with LED Display Generator and

Feature: 1. Working Principle: When the main power supply fails or the voltage is abnormal, the load is automatically transferred from the main to the backup power supply to ensure uninterrupted power supply. After the main power supply is resumed, ATS will automatically transfer the load back to the main power supply. 2. Flexible Setting: This 3 phase automatic changeover switch allows you to freely prioritize mains power, generators, and inverters. The voltage threshold for switching can be set, so it will automatically switch when undervoltage or overvoltage occurs. The switching speed setting range is 1‑600s, with a default of 30s. 3. Parameter Adjustment: Provides stable switching to prevent power fluctuations or interference. The conv
