Features
1 Main Purpose: This transfer switch allows for simultaneous connection of mains, generator, and inverter. When the main power supply fails or the voltage exceeds the set range, it automatically switches to the next power supply. 2 Flexible Setting: This 3 phase automatic transfer switch allows you to freely set the priority order of mains, generator, and inverter, can set voltage thresholds for automatic switching in case of undervoltage or overvoltage. 3 Circuit Protection: This transfer switch provides undervoltage protection, overvoltage protection, and overcurrent protection to ensure the security of your electrical equipment, with 2% voltage measurement accuracy. 4 LED Display Screen: This automatic transfer switch is equipped with 4 LED screens, providing real time voltage readings for each power supply, as well as the voltage and current of the current power supply being used. 5 Adjustable Parameter: Support transfer time, 1-30 second reset time, overvoltage and undervoltage protection threshold, overcurrent protection, and other parameter adjustments, to prevent power system damage.
