    Product Details

    LMS1-LA as our ingenuity research and development of a new generation of dual power automatic transfer switch, in the performance and technology to achieve a major breakthrough. The product provides 63A, 125A, 250A, 400A, 630A and other rated current specifications, whether it is the continuous operation of massive servers in data centers, or the uninterrupted power supply of life support equipment in hospital ICU wards, the stable operation of elevator and fire fighting system in high-rise buildings can fully meet the power demand in different scenarios. ​

    Its switching speed can be called industry-leading, switching time only 10ms-50ms, with millisecond response speed to complete power conversion. In the data center, the LMS1-LA automatic transfer switch can switch to the standby power supply in a very short period of time in the face of sudden power failure, avoiding data loss and system collapse caused by momentary power failure; in the hospital environment, the LMS1-LA automatic transfer switch can switch to the standby power supply in a very short period of time, millisecond-level power switching can guarantee the stable operation of precision instruments and first-aid equipment in operating rooms, and escort the safety of patients. When applied to high-rise buildings, fast power changeover ensures smooth parking of elevators, normal operation of fire fighting systems and improved building Factor of safety. ​
    The transfer switch is composed of a high performance excitation contactor and an intelligent controller. When working, the electromagnetic coil produces a strong and stable attraction to drive the switching action to ensure the instant completion of power switching. This feature not only effectively guarantees the rapid switching of the power supply when the equipment is powered off, but also realizes the seamless connection of the power supply, which provides a reliable and solid power guarantee for the equipment with strict requirements for power continuity. ​

    Intelligent dual power automatic switching system for AC 50 / 60Hz, rated working voltage 400V, rated current up to 630A dual power supply system, to achieve the common power supply (N) with automatic standby power switch (R) between the (also can be used to manually switch).

    LMQ3-W1 intelligent automatic shift switch intelligent dual power automatic switching system for AC 50/60Hz, rated working voltage 400V, rated current 63 ~ 630A dual power system, switch between common power (N) and automatic standby power (R)(can also be used for manual switching). It is composed of integrated controller and intelligent device. The main body is composed of two groups of circuit breakers installed in the switch cabinet to realize two groups of input terminals and one single-chip dual-power conversion switch for output.

    The intelligent device is composed of special forward and backward motors, circuit breakers and operating mechanism. The system has the function of electromechanical double interlock protection, which provides a safe and reliable guarantee for power supply.
