A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a ...
The "Firetrol" branch of ASCO provides power transfer switches, controls, and alarms for fire suppression. ASCO's headquarters is located in Florham Park, New Jersey . With over 1400 employees and 500,000 square feet of manufacturing floor space, it is the world's largest manufacturer of power transfer switches.
A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.

It is a less-expensive alternative to purchasing and installing a dedicated transfer switch. The kit achieves the same function by adding an external interlock onto an existing breaker panel that allows the main breaker to be turned on or one designated load breaker to be turned on, but not both at the same time. The interlocked load breaker is ...
In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [ 1 ] [ 2 ] SVCs are part of the flexible AC transmission system [ 3 ] [ 4 ] device family, regulating voltage, power factor, harmonics and stabilizing the system.
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.
