What does STS mean in electrical?

Static Transfer Systems
Static Transfer Systems (STS) Static Transfer Systems (STS) are intelligent units that transfer the load to an alternative source when the primary source is out of tolerance. This ensures “high availability” of the power supply for sensitive or critical installations.

What is STS switch?

STS(Static Transfer Switch), is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time of less than a cycle (20ms).

What is an STS panel?

Static Transfer Systems (STS) are intelligent switches providing increased supply availability, automatically transferring loads to alternative power sources when the primary power source fails or is not available. They enable flexible site maintenance ensuring high availability.

What is the difference between an ATS and STS?

A Static Transfer Switch (STS) utilizes a static electronic component (SCR), which permits a transfer in less than four milliseconds (1/4 of an electrical cycle). On the other hand, an Automatic Transfer Switch (ATS) relies on moving parts, and makes a significantly slower transfer than Static Transfer Switches.

What is STS in data centers?

1 Static Transfer Switch (STS) An STS is a switch that uses a semiconductor to divert the data center load between the utility source and emergency power. It is controlled by a sensor circuit.

What is UPS and ATS?

Automatic Transfer Switches (ATS) are typically used to provide resilience for smaller uninterruptible power supplies (below 10 kVA) that can’t operate in parallel. Both ‘A’ and ‘B’ supplied from two separate UPS outputs. Both ‘A’ and ‘B’ supplied from two separate mains supplies.
