Product Introduction
KNQ2-80SE Series Household Automatic Transfer Switch (ATS) is the latest micro household power transfer switch independently developed and manufactured by our company. As a PC-grade infrequent switching device with a two-stage structure, this ATS Automatic Transfer Switch Slim Model is suitable for AC distribution systems rated at 50/60Hz and 10-80A.
Primarily designed to monitor the status of user power sources, the ATS Automatic Transfer Switch Slim Model instantly transfers the load to the alternative power source upon detecting an abnormality in one circuit. The switch incorporates mechanical and electrical dual interlock mechanisms, preventing the simultaneous closure of both power sources. Thanks to the compact design of the ATS Automatic Transfer Switch Slim Model, it ensures continuous, reliable, and safe power supply while saving installation space.

Performance and Characteristics
Utilizes an excitation-type electromagnetic drive mechanism for extremely fast transfer. Default control voltage: AC 220V (customizable to AC 110V).
The switch housing features illuminated indicators for Normal Power Source, Alternate Power Source, and Load Circuit, ensuring clear visual confirmation of operational status.
In automatic mode, the switch provides auto-transfer with restoration functionality;
when both Power Source I and Power Source II are available, Source I is prioritized for power supply.
Featuring a modular design with same-side terminal configuration for simplified wiring, the compact unit (≤0.5kg total weight) enables effortless mounting and maintenance.
The integrated arc-extinguishing system splits arcs into multiple series segments within the arc chute, where electromagnetic forces elongate, cool, and extinguish them. Encased in fire-resistant housing (UL94 V-0 rated) with conformal-coated PCBs (IPC-CC-830B compliant), the unit ensures flame resistance and environmental durability in harsh conditions.
Integrated power sampling lines (eliminating external control wiring) enable automatic transfer functionality upon completion of main circuit connections.
