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.
- Working mode depends on the setting of controller, two position LA type ATS only available for self-input and self-recover.
Working Environment
Ambient air temperature:
ambient temperature -5℃ to +40℃, and the 24-hour average temperature value does not exceed Over +35°C. Users whose ambient air temperature is higher than +40°C or lower than -5°C should consult with the manufacturer.
The highest temperature of atmospheric humidity:
when the degree is +40℃, the relative humidity does not exceed 50%, and the maximum relative humidity per month Degree 90%, resistant to the influence of humid air on the sea, and can allow higher relative humidity at lower temperatures, special measures should be taken for the occasional condensation caused by temperature changes.
Installation altitude:
The altitude of the installation site does not exceed 2000 meters. When used at higher altitudes, the dielectric strength and cooling effect of the air should be considered to be reduced, please consult with the manufacturer.
Pollution level:
The environmental pollution level of the installation site is level 3.
Installation category:
IV.
Installation inclination:
the product is fixedly installed in the cabinet, the maximum inclination is ±22.5°.
Arcing distance:
The arcing distance is 30mm when AC 400V. The arcing distance when AC 690V is 60mm.

Frequently Asked Questions (FAQ)
What controllers can be used with 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 have an output signal to start a generator?
The standard ATS does not include an output signal to start a generator. However, the Y-701 and Y-702 controllers are equipped with this feature.
What is the ambient temperature range required for operation?
The ambient air temperature must be between -5°C and +40°C, with a 24-hour average temperature not exceeding +35°C. For operations outside this range, please consult the manufacturer.
Can this ATS be installed at altitudes above 2000 meters?
The standard installation altitude should not exceed 2000 meters. For higher altitudes, reductions in air cooling and dielectric strength must be factored in; please contact the manufacturer for guidance.
What is the arcing distance of the device?
The arcing distance is 30mm when operating at AC 400V, and it increases to 60mm when operating at AC 690V.
What is the lifespan (mechanical and electrical) of the LMS1-LA model?
The electrical life is rated at 1000 cycles. The mechanical life is rated up to 5000 cycles (or 4000 cycles depending on the specific current configuration).
