What is an STS?
Direct answer
An STS (Static Transfer Switch) is a power system device that automatically transfers a critical load between two independent power sources to maintain uninterrupted operation.
Key takeaways
- Continuously monitors two power sources.
- Transfers load automatically during disturbances.
- Designed for mission-critical environments.
Full explanation
An STS is a critical component of power distribution systems in mission-critical facilities. It provides a redundant power path by continuously monitoring two independent power sources, typically a utility source and a backup generator or alternate feed.
If a power disturbance or outage occurs on the preferred source, the STS automatically transfers the load to the alternate source. This transfer occurs fast enough to prevent interruptions to sensitive equipment.
LayerZero offers advanced STS systems designed for safe, reliable, and high-speed power transfer, supporting continuous operation of critical loads.
