product details
LMS1-GN double power automatic transfer switch is suitable for automatic transfer between two power sources in emergency power supply system with rated working voltage of 400V and below,rated frequency of 50Hz and rated current of 16A to 3200A,to ensure continuous,safe and reliable operation of important loads (such as fire fighting load).
Integrated Compact Design: using 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 the installation space, makes the wiring more convenient, and effectively improves the installation efficiency.
Comprehensive fault detection function: two three-phase power over-voltage, under-voltage, lack of phase fault detection, real-time monitoring of power status, once detected abnormal power, can make the judgment quickly and carry on the corresponding operation, guarantees the firefighting equipment the power supply security.
Optional generator control function: optional with electric generator start and stop signal output function, convenient to use with the electric generator, in the common power failure, can timely start the electric generator, provide backup power supply for fire fighting equipment to ensure the normal operation of fire fighting equipment in case of emergency.
Reliable interlock protection: with reliable mechanical interlock device and electrical interlock protection, it can completely eliminate the possibility of two circuit breakers closing at the same time, it can avoid serious faults such as short circuit caused by two power supply at the same time, and ensure the security and stability of the system.
Intelligent Control: the Intelligent Controller takes the monolithic integrated circuit as the control core, the hardware is succinct, the function is formidable, the expansion is convenient, the reliability is high. It can not only accurately detect the state of the power supply, but also realize the intelligent control of the dual power conversion, and can set the automatic conversion parameters freely through the external, such as overvoltage, undervoltage threshold, switching delay time, etc.

    1.Operation button:The operation button is used to control the switch in the manual state,and is used to switch the hand/automatic state.You can also use this button if you want to change the working mode of the product. 
    2 Operating handle:When using the operating handle to operate the switch,the power supply of the main circuit must be cut off or the operating button must be in the manual state. 
    3 Mechanical padlock:when maintenance,first use the operating handle to make the switch in the state of "O off"state,then pull up the mechanical hang. 
    4 Position indication:mark the working position of the switch(I common use,O power off,ll standby).
