TOMZN 2P AC Single Phase Dual Power Automatic Transfer Switch ATS-TOQ7-125A/100A/63A-2
The TOMZN TOQ7 2P Automatic Transfer Switch (ATS) is a dual‑power automatic changeover device designed for single‑phase 220 V–230 V AC electrical systems. It automatically switches the load between the main power supply and a backup source (such as a generator or solar inverter) whenever the main supply fails or becomes unstable, helping ensure continuous power without manual intervention. The ATS supports multiple current ratings (63 A, 100 A, and 125 A) to match different load requirements and features a fast switching time (< 50 ms) for minimal disruption. It is DIN‑rail mountable and built to deliver reliable operation with impulse withstand and stable performance, making it suitable for homes, offices, shops, and critical backup power systems where uninterrupted electricity is needed.
