What is an Automatic Transfer Switch?

How does an Automatic Transfer Switch ATS work?

An Automatic Transfer Switch, abbreviated ATS, supplies end devices with sufficient power. If the primary voltage source fails, the ATS automatically switches to the second voltage source. Connected devices are not affected and can continue to run without any problems. This means that your power supply is constantly maintained. The compact 19″ (inch) transfer switch from EPS, ATS3020RM LOCK G2, is highly available and also has only 1U (height unit) installation height. It can be easily installed directly in the 19″ rack . The ATS3020RM LOCK G2 has two power inputs and thus offers a redundant power supply.
