LMS1-LA Series Manual
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.
Model Description
⚠ Notice: The standard controller comes with grid-generator start-stop ports. Communication is optional. 3N represents neutral line overlap transfer.
Working Environment
- Ambient air temperature: The ambient temperature ranges from -5℃ to +40℃, with an average temperature not exceeding +35℃ for 24 hours. Users should consult the manufacturer if the ambient air temperature exceeds +40℃ or falls below -5℃.
- The highest temperature of atmospheric humidity: At +40℃, the relative humidity does not exceed 50%, with a monthly maximum relative humidity of 90%. It tolerates the effects of maritime damp air. Higher relative humidity is permissible at lower temperatures. Special measures should be taken for condensation occasionally produced by temperature changes.
- Installation altitude: The installation site's altitude does not exceed 2000 meters. For higher altitudes, consider decreased dielectric strength and cooling effect of the air and consult the manufacturer.
- Pollution level: The environmental pollution level at the installation site is Level 3.
- Installation category: Installation Category IV.
- Installation inclination: The product is fixedly installed in the cabinet with a maximum inclination of ±15°.
- Arcing distance: The arcing distance at AC400V is ≥60mm.
