This Intelligent transfer switch is designed to supply a single phase 220V load from different power supply, in order to maintain uninterrupted power supply of essential single phase load. According to voltage presence & voltage quality on phases, it will automatically select the optimum power supply and switch the single phase load supply to it.

When Current Power Supply is Over/Under Voltage or Stop, the Phase Transfer Switch will transfer to another power supply automatically. It can cut off the power supply instantaneously when the line has over current faulty, so as to protect the electrical equipment from being damaged.

The Changeover Switch can set which power resource is Priority. When Priority Phase Recovery to Normal Voltage, the Phase Transfer Switch will Change Back to Priority Power Resource. A-B-C, A-C-B, B-A-C, B-A-C, C-A-B, C-B-A.

Great importance is attached to technological research and development, striving to build an automated electrical equipment and digital production line base that enhances traditional industries through automation, gathering a highly skilled technical team; Committed to building a professional protection electrical laboratory. Ensuring the stability and innovation of products.
