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.
LMQ3-63W1 Automatic Transfer Switch is suitable for AC 50Hz/60Hz, rated working voltage 230V/400V and below power distribution and control circuit. The current up to 63A. It is mainly used as the main switch of terminal electrical appliances, and can also be used to control various types of motors, low-power electrical appliances, lighting and other places.
✔ Complies with GB/T14048.11 and IEC947-6-1 standards.

Control Panel Description
①
Auto/Manual Mode Control Switch: When the control switch is at the right position, it is in automatic mode. When at the left position, it is in manual mode.
②
Main Power Indicator: On when main power voltage is normal. Turns off when main power phase is missing. Flashes rapidly at 10Hz when main power overvoltage. Flashes slowly at 2Hz when main power undervoltage.
③
Emergency Power Indicator: On when emergency power voltage is normal. Turns off when emergency power is abnormal.
④
Emergency ON Indicator: On when the emergency circuit breaker is closed. Flashes slowly at 2Hz when the emergency circuit breaker trips.
⑤
Main ON Indicator: On when the main circuit breaker is closed. Flashes slowly at 2Hz when the main circuit breaker trips.
⑥
Terminal 1, 2 and 3 — Start Generator Output Terminal: When the main power supply is normal, port 3 and 2 will turn off, and port 1 and 2 will turn on, and port 3 and 1 will turn off. It is recommended to connect normally closed contacts port 3 and port 2.
⑦
Terminal 4–5: Main power ON state passive output port.
⑧
Terminal 6–7: Emergency power ON state passive output port.
⑨
Terminal 8–9: RS485 communication port.
⑩
Terminal 10–11 Fire Input: When DC 9~48V is input, the switch turns to OFF position. If you need to release the fire state, you can manually pull the Manual/Auto switch, and turn the switch in the desired position.
