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

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 uninterrupted power supply. After the main power supply is resumed, ATS will automatically transfer the load back to the main power supply. Flexible Setting: This 3 phase automatic changeover allows you to freely prioritize mains power, generators, and inverters. The voltage threshold for ing can be set, so it will automatically when undervoltage or overvoltage occurs. The ing speed setting range is 1‑600s, with a default of 30s. Parameter Adjustment: Provides stable ing to prevent power fluctuations or interference. The conversion time, reset time, overvoltage or undervoltage guard, and overcurrent guard parameters can all be adjusted within the specified range. Item Type: Automatic Transfer Material: Flame Retardant PC Power Terminals: N, L1, L2, L3 Automatic Reclosure Delay (Ton): 1-600s Return Priority Phase Delay: 1-600s
