    FAQ

    Q1: What is a dual power automatic transfer switch (ATS)?

    ATS automatically switches loads between utility power and backup power. It monitors power circuits and shifts power supply instantly once mains fails, keeping elevators, fire control and monitoring equipment running. Unlike battery-powered UPS, it often matches generators as backup power for Class I & II load facilities.

    Q2: What is the main difference between ATS and UPS?

    Both prevent power interruption, but ATS uses external backup generators while UPS relies on built-in battery packs for emergency power. They fit different power demand scenarios.
