Autotransformer Start Cabinet for 380V-660V 90KW-400KW

The backup diesel generators, emergency cooling fans and other equipment in large data centers often have motor power ranging from 90kw to 400kw. Once the power grid is cut off, these backup devices need to start up quickly and stably to ensure the continuous operation of core equipment such as servers. This 380V-660V voltage autotransformer reduced-voltage starting cabinet, with its rapid start-up response and high power carrying capacity, has become a key component of the backup power supply system in data centers. ​ The data center has extremely high requirements for the start-up speed of backup equipment. This start-up cabinet, by optimizing the electromagnetic control circuit, shortens the tap adjustment response time to 0.5 seconds. It can quickly reduce the start-up current to 42%-64% of the direct start-up current after the power grid is cut off, ensuring that the backup generator and cooling fan can be started within 10 seconds. Avoid data loss caused by power failure or over…
