The dual-power control cabinet is a power protection device that achieves seamless switching between primary and backup power sources via an automatic transfer switch. Its core function is to ensure uninterrupted and reliable power supply. This equipment incorporates main line and backup line access modules, utilizing a mechanical interlocking structure in conjunction with an intelligent processor to coordinate the switching process, with a switching time controllable within 200 milliseconds.

Typical applications span high-rise buildings, hospitals, financial institutions, and other facilities demanding stringent power stability. Enhanced variants incorporate integrated voice alarms, anti-theft alerts, and modular wiring capabilities. Through the combination of components like circuit breakers and temperature sensors, safety mechanisms such as overcurrent protection and thermal monitoring are established.
