The MLQ2-125 Automatic Transfer Switch (ATS) Generator Controller is a device used to facilitate the automatic transfer of power between two power sources, typically between a main electrical supply and a backup generator. It is designed for single-phase or 2-phase configurations and has a 4-pole design. This specific ATS model has a current rating of 63A, meaning it can handle a maximum current of 63A. It is commonly used in applications where a reliable and seamless power transfer is required, such as in critical infrastructure or mission-critical systems. The MLQ2-125 ATS allows for dual power changeover, meaning it can switch between two power sources. This is particularly useful in situations where a backup power source is required to ensure uninterrupted power supply during power outages. The controller facilitates the automatic switching process by monitoring the power status of the main supply and the generator. When a power failure is detected on the main supply, the controller immediately activates the generator and seamlessly transfers the electrical load to the generator. Overall, the MLQ2-125 ATS is a reliable and efficient solution for automatic power transfer applications, providing a seamless transition between power sources and ensuring continuous operation of critical electrical systems.
