Keeping this in view, what is the difference between 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.
Similarly, what is STS in data Centre? Static Transfer Switch (STS) is Static Electric device which designed to automatically transfer load for preferred power source to standby power source connected to its input in case of disruption in former and visa versa without any interruption of server room load.
Beside this, how does an STS work?
The function of the STS is to maintain electrical power to a critical load by switching between two relatively independent voltage sources. Whenever it senses a disturbance, the STS automatically transfers electric power supply from the primary to an alternate feeder.
What does a static transfer switch do?
A static transfer switch uses power semiconductors such as Silicon-controlled rectifiers (SCRs) to transfer a load between two sources. Because there are no mechanical moving parts, the transfer can be completed rapidly, perhaps within a quarter-cycle of the power frequency.
