Automatic Transfer Switch

Automatic transfer switches are designed to ensure a safe power supply that automatically transfers the power supply from the primary source to the backup source within 20 microseconds in the event of a failure or outage of the primary source. When the primary power supply recovers, power will automatically switch back to the primary power supply. This is especially useful in locations where uninterrupted power is a must, such as firefighting facilities, hospitals, and food service industries.

This automatic transfer switch can be customized according to your special requirements. Please don’t hesitate to contact us for more information.
