Dual power change-over switch EQ1 400A 3P 690V

EQ1 Automatic Transfer Switch. It is an essential electrical device used to automatically switch between two power sources, typically the main power supply (utility power) and an auxiliary or backup power source (such as a generator or an uninterruptible power supply, UPS). ATS plays a critical role in ensuring a continuous and uninterrupted power supply to critical loads, such as data centers, hospitals, manufacturing facilities, and various other applications. The ATS is controlled by an electronic controller that monitors the voltage and frequency of both power sources. It is responsible for initiating the transfer when necessary, ensuring synchronization, and preventing potentially damaging situations, like overlapping sources. If the utility power supply experiences a problem, such as an outage, voltage sag, or frequency deviation. The ATS controller detects the issue through its sensors and then initiates the transfer sequence. ATS systems are vital for mission-critical applications where even a momentary loss of power can have severe consequences. Proper installation, regular maintenance, and adherence to safety and electrical codes are crucial for their reliable and safe operation.
