    FAQ

    Q1: How does the ATS automatic transfer switch work?

    The ATS supports emergency power systems to automatically switch loads between main and backup power for steady operation of key devices. Its built-in controller samples dual-source voltage constantly, and the microprocessor sends switch commands with adjustable delay to shift power or cut off both circuits. The ATS also displays power faults in real time through its LCD screen and indicator lights.

    Q2: What is the difference between integral type and split type ATS?

    The integral ATS integrates the control panel and main switch body inside one single housing, featuring simple wiring and quick installation for residential villas, small shops and household PV storage systems. The split ATS separates the main switching unit and control display panel; the panel can be mounted separately on cabinet doors, making the ATS ideal for high-current industrial power distribution, fire pump rooms and large commercial energy storage stations for easier daily operation and maintenance.
