To transfer loads between power sources, automatic transfer switches must (1) carry current continuously, (2) detect power failures, (3) initiate the alternate source, (4) transfer load to the emergency source, (5) sense restoration of power to the normal source, and (6) retransfer load to the normal source.
Two common transfer switches for home generators available are the Automatic Transfer Switch (ATS) and the Manual Transfer Switch (MTS). Understanding the distinctions between these two transfer switches is crucial for homeowners looking to maintain uninterrupted power supply.
An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. When a failure occurs in a primary power system, the ATS invokes a standby power source, such as an uninterruptable power supply.
The transfer switch shifts the load to the emergency power source when power from the generator or back-up utility feed is stable and within prescribed voltage and frequency tolerances. Depending on the facility''s needs and preferences, the transfer process is self-acting or manually-initiated.
A switch that is used to transfer power supply automatically from its main source to a backup power source once it detects a power outage within the main source is known as an automatic transfer switch or ATS. Whenever a power outage occurs within the main power system, then this switch invokes a standby power source like a UPS or
Simply stated, the role of the automatic transfer system is to provide the automatic transfer of power for its associated load group from a normal power source, such as a utility service, to an alternate power source, such as standby generation, in the event the normal source fails.
Automatic switching between power sources. offers automatic transfer switches (ATS), from 40 to 1600 Amperes in range. They have the features and functionality that makes them suitable for diverse applications: industrial plants, docks, airports and data centers.
An Automatic Transfer Switch (ATS) is an electrical switch that automatically transfers power from the primary source (utility power) to a secondary source (backup generator) when it senses a power outage or interruption in the primary source.
Designed for datacenters and other electrically demanding applications, CyberPower Switched Auto Transfer Switch (ATS) PDUs, distribute unfiltered electrical pass-through to receptacles from redundant plugs. Outlets can be controlled remotely or locally, as well as individually or collectively.
Eaton''s automatic transfer switches (ATS) are UL 1008 listed for use in emergency, legally required, COPS or standby power systems and designed to transfer critical electrical loads between preferred and alternate/generator power sources.
