These may form part of an automatic transfer switch system for standby power.

With regular generators, an automatic transfer switch is used to connect emergency power.

The system operated an automatic transfer switch which operates the emergency lights in case of power failure.

One example is an open transition automatic transfer switch (ATS).

Automatic Transfer switch, in an electrical system, switches power automatically to a generator or other standby power source after a power interruption.

After utility power returns, the automatic transfer switch transfers the electrical load back to the utility and signals the standby generator to shut off.

ASCO Power Technologies was founded in 1880 and developed the first commercially available automatic transfer switch in 1920.

This method uses critical devices such as an automatic Transfer switch and IGBT Modules in order to operate.

Generac manufactures gaseous-fueled, diesel-fueled and bi-fuel engine-driven power generation equipment, modular paralleling systems, automatic transfer switches and small engines.

Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator.
