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.
Y-700 series ATS controller is intelligent dual-supply switch module, which integrates a programmable function, automatic measurement, LCD display, and digital communication. It combines digital, intelligent, networking, measurement and control process automation, disoperation, in order to reduce the faults during operation. It is the best ideal option in ATS. Y-700 series ATS controller is made of microprocessor as its core, can accurately detect extended-spectrum 2-way-3-phase voltage and also make accurate judgment and output passive control switch under the abnormal voltage(over and under voltage,miss phase and over and under frequency).
This controller has full consideration in various application of ATS (automatic transfer system) can be directly used for Intelligent ATS, Contactor ATS, Circuit Break ATS etc. It have compact structure, advanced circuits,simple wiring and high reliability,be widely used in Electric power, Telecommunications, Petroleum, Coal,Metallurgy, Railways, Municipal, Intelligent building, Electrical devices,Automaticcontrol and Testing system etc.

Frequently Asked Questions (FAQ)
What is the main application of the Y-700 series ATS controller?
The Y-700 series ATS controller is an intelligent dual-supply switch module designed for automatic transfer systems (ATS). It is widely used in electric power, telecommunications, petroleum, metallurgy, railways, intelligent buildings, and automatic control systems.
Which types of ATS systems can this controller work with?
It is highly versatile and can be directly integrated into various ATS configurations, including Intelligent ATS, Contactor ATS, and Circuit Breaker ATS.
What voltage ranges does the Y-700 series support?
It supports a wide operating voltage range, including DC 8.0V to 35.0V constant power supply, HTS220/HWS560 power modules, and AC power L1N1/L2N2 with voltage ranges of AC 160V to 280V (specifically for Y-700/B and Y-700/BI models).
What kind of communication interface does the controller have?
The controller features an RS485 communication port and supports the standard MODBUS protocol, allowing easy networking and integration into digital control systems.
What is the ingress protection (IP) rating of this controller?
