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.
The Y-800 busbar controller is used to control three frame circuit breakers, realize the conversion of two power supplies and the busbar connection on the load side. It is based on microprocessor, which can detect the voltage of two three-phase incoming lines accurately, make accurate judgment on the voltage abnormality (overvoltage, undervoltage, over frequency, under frequency, missing phase, reverse phase sequence), complete the power conversion and the connection and disconnection of the bus on the load side according to the given logic, and output the passive control switch to complete the control of the load, display the system status and other functions. The controller is equipped with electrical interlock accessories, which cooperate with mechanical interlock to realize redundant interlock system and improve the reliability of operation. The product has compact structure, simple wiring and high reliability. It can be widely used in electrical automatic control systems of power, telecommunications, petrochemical, mining, rail transit, municipal, data center, intelligent building and other industries.
