ACU132 Automatic Transfer Switch Controller

Description:

The ACU132 Automatic Transfer Switch Controller is an electronic control module used in automatic transfer switch (ATS) systems to manage switching between utility and generator power sources. It continuously monitors voltage and frequency conditions and initiates transfer commands to maintain uninterrupted power supply during mains failure or instability.

Applications:

The ACU132 Automatic Transfer Switch Controller is used in generator backup systems, industrial power distribution panels, commercial facilities, telecom infrastructure, and critical load applications requiring continuous power availability. It is commonly integrated into ATS panels to control switching between utility and standby generator sources for automation and fault response.
