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.
LMS1-MA uses a unique two-bit structure, ingenious design to save space at the same time, to achieve excellent performance. Its wide range of applications, perfectly adapted to AC 50/60Hz, AC400V power supply environment. Rated current coverage of 6A–63A, it can easily meet all kinds of household appliances electricity needs — whether it is daily lighting, small household appliances, or larger power air conditioners, electric water heaters, etc., it can provide stable power supply.
Features
- ✓ The excitation electromagnet is adopted for actuation, the conversion speed is extremely fast, and the control voltage is AC220V (AC110V can be customized).
- ✓ The switch body is provided with power-on indication of common power supply / standby power supply, and the switch state is clear.
- ✓ Automatic mode has the function of self-input and self-recover. When two power supplies exist at the same time, the common power supply gives priority to power supply.
- ✓ Rail installation mode, modular structure design, total weight < 0.9Kg, compact structure, small volume and convenient installation and maintenance.
Model Description
Working Environment
- 🌡 The operating ambient temperature ranges from -5℃ to +40℃, and the average temperature within 24 hours does not exceed +35℃. The storage ambient temperature ranges from -25℃ to +55℃, and can reach +70℃ in a short time (within 24 hours).
- ⛰ The altitude of the installation site must not exceed 2000m.
- 💧 The relative humidity of the air at the installation site does not exceed 50% when the ambient air temperature is +40℃. The relative humidity can be higher at a lower temperature. For example, when the average minimum temperature in the wettest month is +20℃, the monthly average maximum relative humidity can reach 90%. Appropriate measures should be taken to prevent condensation due to temperature changes.
- ⚡ Pollution Class 3 (conductive pollution, or dry non-conductive pollution to conductive due to condensation). ATS can be installed in the cabinet vertically or horizontally. If you have special installation requirements, please contact us.
- 🛡 The protection grade of the shell is IP30.
- 📊 Overvoltage category: Main circuit — Class III; Control and auxiliary circuits — Class II.
