Adopting professional PC level isolation structure and 4-pole modular design, this product realizes safe and fast automatic switching between common power supply and standby power supply, widely used in high-demand places requiring continuous power supply.

Built with advanced mechanical interlock and electrical interlock technology, it effectively avoids parallel connection of two power supplies and ensures safe operation. With fast and stable conversion action, it can complete power switching within a short time when the common power fails, and automatically switches back to the common power after recovery, realizing unattended automatic management. As an isolation-type PC level ATS, it has excellent on-off isolation performance, clear status indication, and strong short-current withstand capacity, providing reliable electrical isolation between power sources and loads.
