    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-J automatic transfer switch can switch intelligently and efficiently. In case of power failure, abnormal voltage and frequency fluctuation of the main power supply, the built-in sensor quickly captures and the automatic transfer switch acts in millisecond time to switch the load to the standby power supply to ensure the continuous operation of the equipment.

    Product real-time monitoring of the main, standby power status, with advanced circuits and software algorithms to track voltage, current, frequency parameters. When the parameters deviate from the normal range, the alarm is issued, and the abnormal time and type are also recorded, which is convenient for subsequent query and analysis.

    Frequently Asked Questions
    Q What is the transfer time of the LMS1-J automatic transfer switch?
    The LMS1-J ATS has a transfer time of 1.5 to 3 seconds. The built-in sensor detects power anomalies in milliseconds and triggers the switching action to ensure minimal disruption to connected equipment.
    Q What rated current options are available for the LMS1-J series?
    The LMS1-J series is available in the following rated current options: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A, making it suitable for a wide range of load requirements.
    Q Does the LMS1-J support both automatic and manual operation?
    Yes, the LMS1-J automatic transfer switch supports both auto and manual functions. It can automatically switch to the standby power supply upon detecting a main power failure, and can also be manually operated when needed.
    Q What safety interlocks does the LMS1-J provide?
    The LMS1-J features both electrical interlock and mechanical interlock mechanisms. These dual interlocks ensure that the main and standby power supplies can never be connected simultaneously, preventing dangerous back-feeding situations.
    Q What are the installation environment requirements for the LMS1-J?
    The LMS1-J should be installed at an altitude no higher than 2,000 meters, in an ambient temperature range of -5℃ to +40℃, with relative humidity not exceeding 50% at 40℃. The environment must be free of explosive gases, corrosive elements, and conductive dust (Pollution Degree 3).
    Q What is the mechanical lifespan of the LMS1-J transfer switch?
    The LMS1-J automatic transfer switch has a rated mechanical life of 10,000 operating cycles, ensuring long-term reliability and durability in continuous power management applications.
