3 Phase Over Under Voltage Protector 4 LED Display 35mm DIN Rail Automatic Transfer AC220V 40A

[Voltage Transfer ] The 3 phase voltage transfer allows for simultaneous connection to the mains, generator, and inverter. When the main power supply fails or the voltage exceeds the set range, it automatically es to the power supply. [Flexible Settings] This automatic transfer allows you to set the priority order of the mains, generator, and inverter. You can set the voltage threshold for automatic over during under or over voltage situations. [Multiple s] Offering under voltage, over voltage, and over current , the over under voltage protector ensures the of your electronic devices and prevents damage.
