Description Automatic Transfer Switch (ATS)

NEW ATS - Automatic Transfer Switch
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.

ATS series as the main, dual power automatic transfer switch is mainly used in the first class load and second class load (which need back-up power) confirmed by the nati- onal regulations , suitable for highrise buildings, post and telecommunications, coal and shipping, industrial assembly line, health care, military facilities, etc. The main standby power can be grid, generator, battery, etc. The main standby power can be customized by users. Transfer time of the main switch body is not more than 1s. Users can make special delay when necessary. The main power takes priority over the main standby power when supply electricity together.


How Does an Automatic Transfer Switch Work?
An automatic transfer switch (ATS) is an intelligent device that switches power connections between the primary and alternate sources without human intervention or supervision. Also, ATS uses dedicated control logic to deliver us a continuous power supply using more than one power connection, which can be utility power sources, generators, UPS, solar panels, etc.

The main purpose of ATS is to maintain the power supply for connected loads in an electrical distribution system without any interruption, using all available power sources.

The control logic, also known as the automatic controller, is a microprocessor-based device that has the ability to measure and monitor different parameters of connected power sources. These electrical parameters are frequency, voltage, charge intensity, and more.

When one power source fails to deliver the required magnitude of electrical parameters for the connected loads in your electrical distribution system, ATS instantly switches the connection to the alternate power source if it is available.

Generally, utility power connections are set as primary power sources in ATS configurations, and generators, UPS, and solar panels are set as alternate power sources.

ATS works in a sequence to deliver electrical power using different sources, which happens in the following way.

Your utility power source becomes unavailable.
ATS transfers your load to an alternate power source.
When the primary power source becomes available, ATS switches back to it.
