    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. ​

    Dual Power Automatic Transfer Switch is the key equipment to ensure the continuous power supply. It can monitor the main and standby power supply in real time. Once the main power supply fails, it can automatically switch to the standby power supply within tens of milliseconds to ensure that the load power supply does not stop. With the characteristics of mechanical and electrical interlocking, zero-crossing, indication isolation and good Electromagnetic compatibility, it is widely used in hospitals, high-rise buildings, data centers, industries and other scenarios that require reliable power supply.

    ? Frequently Asked Questions
    Q What is a Dual Power Automatic Transfer Switch (ATS) and how does it work?
    A Dual Power Automatic Transfer Switch (ATS) is a device that continuously monitors both the main and standby power supplies. When it detects a failure in the main power supply, it automatically switches the load to the standby power source within tens of milliseconds, ensuring uninterrupted power delivery to critical equipment.
    Q What rated current options are available for the LMS1-SN Automatic Transfer Switch?
    The LMS1-SN ATS is available in five rated current options: 800A, 1000A, 1250A, 1600A, and 2000A, making it suitable for a wide range of industrial and commercial power distribution applications.
    Q What are the typical application scenarios for this Automatic Transfer Switch?
    This ATS is widely used in scenarios that demand highly reliable and continuous power supply, including hospitals, high-rise buildings, data centers, and various industrial facilities where power interruption could cause serious operational or safety risks.
    Q What standards does the LMS1-SN Automatic Transfer Switch comply with?
    The LMS1-SN ATS complies with Chinese national standard GB/T 14048.11 and international standard IEC 60947-6-1, ensuring it meets rigorous safety and performance requirements for low-voltage switchgear and controlgear.
    Q Which controllers are compatible with the LMS1-SN ATS?
    The LMS1-SN Automatic Transfer Switch is compatible with the following controllers: Y-700, Y-701, Y-702, and Y-703, offering flexible integration options for different control and monitoring requirements.
