Varuvahetuslülitid

Varuvahetuslülitid, also known as automatic transfer switches (ATS), are electrical devices that automatically switch a power source from a primary source to a secondary source in the event of a primary power failure. This ensures that critical equipment continues to receive power without interruption. The primary power source is typically the utility grid, while the secondary source is often a generator or an uninterruptible power supply (UPS).

The operation of a varuvahetuslüliti is typically based on monitoring the voltage and frequency of the primary power source. When these parameters fall outside of a predefined acceptable range, the switch initiates a transfer sequence. This sequence involves first disconnecting the load from the primary source and then connecting it to the secondary source. Once the primary power source is restored and stable, the varuvahetuslüliti can be programmed to automatically transfer the load back to the primary source.

Varuvahetuslülitid are crucial for maintaining the reliability of power supply in various applications, including hospitals, data centers, telecommunication facilities, and industrial plants. They are designed to be fail-safe and are tested regularly to ensure their proper functioning. The size and complexity of varuvahetuslülitid can vary depending on the power requirements of the load they are protecting and the type of secondary power source being used. They are an essential component in ensuring business continuity and preventing data loss or damage to sensitive equipment during power outages.
