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:
- Separated type ATS can be chose Y-701(LED) or Y-702(LCD) Controller.
- ATS without output signal to start generator, Y-701 and Y-702 controller with it.

Frequently Asked Questions (FAQ)
What controllers can be selected for the separated type ATS?
You can choose either the Y-701 (LED) or the Y-702 (LCD) Controller for the separated type ATS.
Does the ATS include an output signal to start a generator?
The standard ATS does not come with an output signal to start a generator. However, the Y-701 and Y-702 controllers are equipped with this generator start signal feature.
What are the ambient temperature requirements for operation?
The ambient air temperature should range between -5℃ and +40℃, with the 24-hour average temperature not exceeding +35°C. For temperatures outside this range, please consult the manufacturer.
What is the maximum installation altitude for this switch?
The standard installation altitude should not exceed 2000 meters. If using at higher altitudes, you must account for reduced dielectric strength and cooling effects of the air, and consult with the manufacturer.
What is the typical transfer time for the LMS1-LA model?
For A Power, the input time is 80ms to 100ms and the break time is 30ms. For B Power, the input time is 100ms to 120ms and the break time is 30ms.
What are the electrical and mechanical lifespans of the switch?
The LMS1-LA switch has an electrical life of 1000 cycles. The mechanical life is 5000 cycles for lower current ratings and 4000 cycles for higher ratings (315A~630A).
