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.
