The ATS DB typically includes a set of transfer switches, which are used to transfer power from the primary power source to the backup power source, and vice versa. The panel also includes a control system that monitors the status of the primary power source and automatically initiates a transfer to the backup power source in the event of a power failure or other interruption.
The ATS DB also includes metering devices, such as ammeters and voltmeters, that can be used to monitor the electrical usage and identify any potential issues. It also includes protection devices, such as overcurrent protection, earth-fault protection, and residual current protection, that are designed to protect the electrical system and equipment from damage in case of faults or overloads.
In summary, an Automatic Transfer Switch (ATS) Distribution Board (DB) is an electrical device used to automatically transfer electrical power from one source to another in the event of a power failure or other interruption in the primary power source. It typically includes transfer switches, control system, metering devices, and protection devices to monitor the power supply, protect the electrical system and equipment from damage, and ensure a safe and reliable power supply to critical facilities such as hospitals, data centers, and other facilities where a reliable and uninterrupted power supply is essential.
