Automatic Transfer Switch (ATS)

An Automatic Transfer Switch (ATS) is an essential component in electrical systems that require uninterrupted power. It automatically switches the power supply from the main source to a backup generator or secondary source when it detects a failure or interruption in the primary source.

ATS units ensure continuous operation of critical systems in hospitals, data centers, commercial buildings, and industrial facilities. Once normal power is restored, the switch automatically transfers the load back to the primary source without manual intervention.

Benefits With Our ATS

Seamless power transfer and enhanced system reliability across various applications.

  • Fully automatic power source switching for uninterrupted operations
  • Compatible with diesel generators, solar inverters, and grid supply
  • Intelligent control features for monitoring and diagnostics

Our Automatic Transfer Switches are engineered to meet IEC and UL standards, supporting a wide range of voltage and current ratings. They are available in open transition, closed transition, and delayed transition configurations based on system requirements. With rugged construction and smart technology, they ensure reliability, safety, and performance in mission-critical environments.

Most Common Questions

What is the purpose of an Automatic Transfer Switch? ATS ensures seamless power supply by automatically switching to a backup source during outages. This prevents downtime and protects sensitive equipment in power-critical systems.

An ATS automatically switches the electrical load from the primary power source to a backup source (like a generator) in the event of a power outage. When utility power is restored, the ATS returns the load to the primary source, ensuring continuous and reliable power supply.
ATS units are used in critical applications that require uninterrupted power such as hospitals, data centers, telecommunication facilities, commercial complexes, industrial plants, and emergency response systems.
There are several types of ATS, including open transition (break-before-make), closed transition (make-before-break), and delayed transition switches. The selection depends on the application’s criticality and type of power system being managed.
Yes, like all critical power components, ATS should be tested and maintained periodically. Regular inspections help ensure mechanical components, control logic, sensors, and switching mechanisms function properly, especially in emergency conditions.
