CNC | New Arrival as YCQ9s Dual Power Automatic Transfer Switch

An automatic transfer switch (ATS) is a device used in electrical power systems to automatically transfer power supply between two sources, typically between a primary power source (such as the utility grid) and a backup power source (such as a generator). The purpose of an ATS is to ensure uninterrupted power supply to critical loads in the event of a power outage or failure in the primary power source.

Here’s how an automatic transfer switch typically works:

Monitoring: The ATS constantly monitors the voltage and frequency of the primary power source. It detects any abnormalities or disruptions in the power supply.

Normal Operation: During normal operation when the primary power source is available and within specified parameters, the ATS connects the load to the primary power source and ensures a continuous power supply. It acts as a bridge between the power source and the load, allowing the electricity to flow through.

Power Failure Detection: If the ATS detects a power failure or a significant drop in voltage/frequency from the primary power source, it initiates a transfer to the backup power source.

Transfer Process: The ATS disconnects the load from the primary power source and isolates it from the grid. It then establishes a connection between the load and the backup power source, usually a generator. This transition happens automatically and quickly to minimize downtime.

Backup Power Supply: Once the transfer is complete, the backup power source takes over and starts supplying electricity to the load. The ATS ensures a stable and reliable power supply from the backup source until the primary power source is restored.

Power Restoration: When the primary power source is stable and within acceptable parameters again, the ATS monitors it and verifies its quality. Once it confirms the power source’s stability, the ATS transfers the load back to the primary source and disconnects it from the backup power source.

Automatic transfer switches are commonly used in critical applications where uninterrupted power supply is essential, such as hospitals, data centers, telecommunications facilities, and emergency services. They provide a seamless transition between power sources, ensuring that important equipment and systems remain operational during power outages or fluctuations.
