    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. ​

    LMS1-NA Series Auto Transfer Switch mainly used for electric distribution network or motor network with rated voltage 380V, 50Hz, rated current 16A to 630A, transfer between main power and backup power system, power grid and genset.

    Frequently Asked Questions
    Q What is the rated voltage and current range of the LMS1-NA Series Auto Transfer Switch?
    The LMS1-NA Series ATS is designed for use with a rated voltage of 380V at 50Hz. It covers a wide rated current range from 16A up to 630A, making it suitable for both small and large distribution or motor network applications.
    Q What is the rated control power supply voltage for all current variants?
    All current variants of the LMS1-NA Series ATS use AC220V as the rated control power supply voltage, regardless of the main circuit current rating (16A to 630A).
    Q What is the mechanical and electrical service life of the LMS1-NA ATS?
    The LMS1-NA Series ATS offers a mechanical service life of 20,000 operations and an electrical service life of 6,000 operations across all current ratings, ensuring long-term reliability in continuous switching applications.
    Q What types of power transfer scenarios does the LMS1-NA ATS support?
    The LMS1-NA Series supports two main transfer scenarios: power grid to power grid (a), and power grid to generator (b). This makes it versatile for both utility redundancy and backup genset applications.
    Q What does the NA terminal on the LMS1-NA ATS represent?
    The NA terminal is the neutral terminal of the normal power supply specifically used in 3-pole ATS configurations. Similarly, the NB terminal serves as the neutral terminal of the standby power supply for 3-pole ATS units.
