    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-NJT series of household automatic transfer switch apparatus is the latest micro household power transfer switch developed and produced by our company. The switch belongs to PC CLASS lightweight transfer switch, Two positions structure, It is suitable for AC 50/60HZ and AC power distribution system of rated current 10A-63A. It is mainly used to detect whether the user's power supply is normal. When one power supply is abnormal, switch to the other power supply immediately. Mechanical and electrical combination locks are used inside the switch, Avoid simultaneous switching on of two lines, So as to ensure the continuity, reliability and safety of power supply.

    Model Description

    automatic-transfer-switch-2-4

    Normal Working Conditions

    1

    The operating environment temperature ranges from -5°C to +40°C, and the average temperature within 24 hours cannot exceed +35°C. The storage environment temperature ranges from -25°C to +55°C, and can reach +70°C within 24 hours.

    2

    The altitude of the installation site does not exceed 2000m.

    3

    The relative humidity of the air at the installation site does not exceed 50% when the ambient air temperature is +40°C. The relative humidity can be higher at a lower temperature. For example, when the mean minimum temperature of the wettest month is +20°C, the mean monthly maximum relative humidity of that month can reach 90%. Appropriate measures should be taken to prevent condensation due to temperature changes.

    4

    Pollution Level 3 (conductive pollution, or dry non-conductive pollution becomes conductive due to condensation). The ATS can be installed vertically or horizontally in the cabinet. If you have special installation requirements, please contact our company.

    5

    The protection level of the product shell is IP30.

    6

    Overvoltage class: III main circuit; Control and auxiliary circuits class II.
