Automatic Transfer Switch (ATS) is made up of an intelligent transfer controller and a 4 poles electro motion load transfer switch. ATS can automatically transfer load between the main power and the emergency power (generating set) without the operator.

When the main power fails or the voltage drops below 80% of normal voltage, the ATS will start the emergency generating set after a preset time of 0-10 seconds (adjustable), and transfer the load to emergency power (generating set). Contrarily, when the main power recovers to normal level, the ATS will transfer the load from the emergency power (generating set) to the main power, and then stop the emergency power (generating set).

The Automatic Transfer Switch (ATS) is an indispensable component of electrical power systems, providing automatic power transfer, redundancy, and reliability. With its versatility, advanced control, and monitoring features, ATS ensures uninterrupted power supply and safeguards the electrical system and connected equipment. Easy installation and maintenance further enhance its appeal. Overall, ATS is an essential tool for maintaining a continuous and reliable power supply in various applications, from residential buildings to industrial plants.
