LMS1-GN 250A Automatic Transfer Switch ATS - Reliable China Suppliers & Factory Solutions

LMS1-GN double power automatic transfer switch is suitable for automatic transfer between two power sources in emergency power supply systems with rated working voltage of 400V and below, rated frequency of 50Hz, and rated current of 16A to 3200A — ensuring continuous, safe and reliable operation of important loads (such as fire fighting loads).

Using a dedicated integrated design, the intelligent controller is installed in the switch body to form a compact structure. The user only needs to put the main circuit into use, which greatly reduces installation space, makes wiring more convenient, and effectively improves installation efficiency.

Two three-phase power over-voltage, under-voltage, and lack-of-phase fault detection with real-time power status monitoring. Once abnormal power is detected, quick judgment and corresponding operations ensure the power supply security of firefighting equipment.

Optional electric generator start/stop signal output function. In the event of common power failure, it can timely start the generator to provide backup power for fire fighting equipment and ensure normal operation in emergencies.

With reliable mechanical interlock device and electrical interlock protection, it completely eliminates the possibility of two circuit breakers closing simultaneously, preventing short circuits caused by dual power supply and ensuring system security and stability.

The intelligent controller uses a monolithic integrated circuit as the control core — succinct hardware, formidable function, convenient expansion, and high reliability. Automatically detects power supply state, realizes intelligent dual-power conversion control, and supports free setting of parameters such as overvoltage/undervoltage thresholds and switching delay time.
