1. AUTOMATIC TRANSFER FUNCTION: When the main power supply fail or the voltage is abnormal, the ATS automatically transfer the load from the main power supply to the standby power supply to ensure uninterrupted power supply. Priority is L1>L2>L3. ATS ensure smooth switching between the primary and backup power supplies, preventing power fluctuations or interference. After the main power supply recovers, the ATS automatically transfer the load back to the main power supply to ensure a seamless system restart

2. FLEXIBLE SETTINGS: This three phase automatic transfer switch enables you to freely prioritize mains power, generator, and inverter. You can set the voltage threshold for switching, so automatically switch when there is under voltage or over voltage. The switch speed can also be set within the range of 1s to 600s, with a default of 30s

3. ADJUSTABLE PARAMETERS: The transfer time, reset time, over under voltage protection, and overcurrent protection parameters are all adjustable within the specified range
