An automatic transfer switch (ATS) is a device that automatically transfers a power supply from transfer switch's primary source to a backup source when it senses a failure or outage in the primary source. Auto transfer switches (ATS) on ATO.com have a wide range of selections with ratings from 6 amps to 3200 amps. ATO offers three kinds of auto changeover switches with their own characteristics and functions, which make it applied to different areas. The transfer switches here can be operated both automatically and manually. 3-pole or 4-pole ATS changeover switch, reliable automatic and manual operation, simple structure, easy operation and long service life.
Intelligent automatic transfer switch applied for residential areas, military facilities, hospitals, shopping malls, airports and so on. Go into a detailed product page and find a suitable ATS automatic transfer switch to changeover the source in case of power failure, so as to guarantee the continuous and reliable operation of the critical equipment.
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 intelligent automatic transfer switch invokes a standby power source, such as an uninterruptable power supply. An ATS can also start up more long-term backup power systems, such as local diesel generators, to run electric equipment until utility power is restored.
Since the transfer switch is connected to both primary and backup power sources, auto transfer switch serves as an intermediary between equipment and the power supplies, acting as an electrical relay. An auto changeover switch can also act as a redundant, rack-mounted power supply for equipment that is connected to a power source with only one cord.
An ATS automatic transfer switch can control when a backup generator depends on the voltage in the primary supply for a building. When they do this they have to also transfer the load to the backup generator. The auto changeover switches work by blocking the backup generator from becoming a source of electrical power until the generator itself is on for temporary power.
Switch to automatic mode. We can see that the normal power and reserve power (backup power) indicators are on. Currently using normal power. When the normal power is disconnected the ATS automatic transfer switches to reserve power. Reserve power output indicator is on. When normal power is restored, ATS automatically switches back to normal power. Switch to normal mode. When the normal power is cut off, the load loses power. Manually switch to reserve power and the load resumes operation. Switch back to automatic mode. After the normal power is restored, the ATS automatically switches back to the normal power mode.
