    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. ​

    Main Functions
    1 Automatic Switching

    When the main power fails, automatically switches to standby power to ensure uninterrupted supply. Once the main power is restored, it automatically switches back and disconnects the standby.

    2 Manual Switching

    Supports manual power switching for easy maintenance and testing.

    3 Condition Monitoring

    Real-time monitoring of main and standby power supply voltage and frequency. Sound and light alarms are triggered when power supply is abnormal.

    4 Protective Functions

    Over-voltage/under-voltage protection, overload protection, and short circuit protection — automatically disconnects to protect equipment and lines.

    5 High Reliability

    High-quality components ensure long-term stable operation with strong anti-electromagnetic interference capability for complex environments.

    6 Multiple Control Modes

    Supports automatic or manual control mode selection. Some models also support remote monitoring and operation.

    7 Easy Installation

    Modular design for easy installation and maintenance. Supports wall-mounted and cabinet installation methods.

    8 Widespread Application

    Suitable for hospitals, data centers, factories, and other locations requiring uninterrupted power supply.

    9 Energy Saving & Eco-Friendly

    Optimized power management reduces energy consumption. Uses environmentally friendly materials that meet environmental protection standards.

    10 Communication

    Supports RS485, Modbus, and other communication protocols for easy integration into intelligent monitoring systems.

    Frequently Asked Questions
    Q What is an Automatic Transfer Switch (ATS) and how does it work?
    An Automatic Transfer Switch (ATS) monitors the main power supply continuously. When it detects a power failure or abnormal voltage, it automatically switches the load to a standby power source — such as a generator or backup grid — within milliseconds. Once the main supply is restored and stable, the ATS switches back automatically.
    Q What is the difference between automatic mode and manual mode on this ATS?
    In automatic mode, the switch responds to power conditions without any human intervention — ideal for critical facilities. In manual mode, an operator controls the switching process directly via the panel buttons, which is useful during maintenance, testing, or when automatic switching needs to be overridden.
    Q What protection features does this Automatic Transfer Switch provide?
    This ATS includes over-voltage and under-voltage protection, overload protection, and short circuit protection. These features automatically disconnect the power supply when abnormal conditions are detected, safeguarding both the connected equipment and the electrical lines.
    Q Which communication protocols does this ATS support?
    The ATS supports RS485 and Modbus communication protocols, making it straightforward to integrate into building management systems (BMS), SCADA platforms, or other intelligent monitoring and control systems.
    Q Where is this Automatic Transfer Switch typically used?
    This ATS is widely used in environments where continuous power is critical, including hospitals, data centers, industrial factories, commercial buildings, and telecommunications facilities. Its reliable switching ensures operations are not disrupted during power outages.
    Q What installation methods are supported, and is the unit easy to maintain?
    The ATS features a modular design that simplifies both installation and ongoing maintenance. It supports multiple mounting options including wall-mounted and cabinet (rack) installation, making it adaptable to a wide range of installation environments.
