Automatic Transfer Switch

An automatic transfer switch (ATS) is a device that automatically switches a power supply from one source to another. It is commonly used in backup power systems to ensure continuous power supply in the event of a primary power failure.

The ATS monitors the primary power source and automatically switches to the backup power source, such as a generator, when the primary power fails. When the primary power is restored, the ATS switches back to the primary power source, ensuring a seamless and uninterrupted power supply.

ATSs are commonly used in critical applications, such as data centers, hospitals, and industrial facilities, where an uninterrupted power supply is essential. They are designed to be highly reliable and can be configured for single-phase or three-phase power, depending on the specific application.

In addition to providing backup power, ATSs can also be used for power management and energy efficiency, as they allow administrators to switch between power sources based on factors such as cost and availability. This can help to reduce energy costs and improve the overall efficiency of the power system.
