Automatic transfer switch (ATS)
Call for Price
An automatic transfer switch (ATS) is a device that automatically transfers power from a primary source to a backup source when the primary source fails or experiences an outage. ATSs are often used in facilities that require continuous or near-continuous power, such as hospitals, data centers, and factories. They are critical components of emergency or standby power systems.
When a power loss occurs, the ATS can detect it and immediately switch to the backup power source in milliseconds. This eliminates power stutters that can cause issues for businesses and industries. ATSs can also start up long-term backup power systems, like diesel generators, to run equipment until utility power is restored. When utility power is restored, the ATS can automatically transfer the load back to the utility and shut down the generator to save fuel.
ATSs are governed by control logic that monitors the electrical parameters of the power sources, and is usually microprocessor-based. Some devices can be handled via a digital panel with LED lights that indicate which supply is powering the structure. From there, you can control aspects like over- and under-voltage thresholds.
