APLAB offers a range of Static Transfer Switch (STS) panels to ensure redundancy in power for critical loads. This unit monitors two input sources continuously, out of which one source will normally feed the critical loads. In case of failure of this input source, the STS will automatically transfer the critical loads to the other input source. The user can also perform transfer from one source to another using the manual transfer switch.
