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.
Configuration of Dual Power Supply Cabinet
1
Automatic Transfer Switch (ATS) for Dual Power Supplies
Commonly, there are PC type and CB type. The PC type transfer switch features a simple structure and fast switching speed, making it suitable for scenarios with high requirements for switching time. The CB type transfer switch has functions of overload and short-circuit protection, and it is applicable to situations where the load needs to be protected.
2
Control Circuit and Controller
The control circuit is responsible for monitoring the power supply status and controlling the operation of the transfer switch. The controller is the core component of the dual-power supply switch, usually adopting microprocessor technology, which has functions of high-precision measurement of power supply parameters and flexible parameter setting.
3
Protection Devices
Overcurrent Protection Device
When the current in the circuit exceeds the set value, the overcurrent protection device will automatically cut off the circuit to prevent equipment damage due to overcurrent.
Short-circuit Protection Device
When a short-circuit fault occurs in the circuit, the short-circuit protection device will act quickly to cut off the circuit and protect the safety of the equipment and the circuit.
Under-voltage Protection Device
When the power supply voltage is lower than the set value, the under-voltage protection device will act to prevent the equipment from malfunctioning or being damaged due to under-voltage.
4
Current Transformers (CTs) and Voltage Transformers (VTs)
Current transformers are used to measure the current in the circuit, and voltage transformers are used to measure the voltage of the power supply. They transmit the measured current and voltage signals to the controller and the protection device for monitoring and protection purposes.
5
Circuit Breakers
The input power supply circuit breaker and the output power supply circuit breaker can automatically cut off the circuit when faults such as overload and short-circuit occur in the circuit, protecting the safety of the equipment and the circuit.
6
Auxiliary Equipment
💡
Indicator Lights
Including the main power supply indicator light, standby power supply indicator light, main power switch-on indicator light, standby power switch-on indicator light, etc. Different on/off states reflect the power supply and working conditions, making it convenient for personnel to intuitively understand the operating status of the device.
🔘
Operation Buttons
Used for manually operating the switching of the dual-power supply transfer switch, as well as for debugging and maintaining the equipment.
⚙️
Relays
Used to achieve the conversion and amplification of control signals and to perform logical control of the circuit.
Frequently Asked Questions (FAQ)
Q
What is the main difference between PC type and CB type Automatic Transfer Switches?
The PC type ATS features a simpler structure and faster switching speed, making it ideal for applications where switching time is critical. The CB type ATS, on the other hand, includes overload and short-circuit protection functions, making it more suitable for scenarios where the connected load also requires protection.
Q
What role does the controller play in a dual power supply cabinet?
The controller is the core component of the dual-power supply switch. It typically uses microprocessor technology to perform high-precision measurement of power supply parameters, monitor the status of both the main and standby power supplies, and control the transfer switch operation. It also allows flexible parameter setting to suit different application requirements.
Q
How do protection devices in a dual power supply cabinet safeguard equipment?
The cabinet incorporates three key protection devices: the overcurrent protection device automatically cuts off the circuit when current exceeds a set value; the short-circuit protection device acts quickly to disconnect the circuit during a short-circuit fault; and the under-voltage protection device responds when the supply voltage drops below the set threshold — all working together to prevent equipment damage.
Q
What is the function of Current Transformers (CTs) and Voltage Transformers (VTs) in the cabinet?
Current Transformers (CTs) measure the current flowing through the circuit, while Voltage Transformers (VTs) measure the power supply voltage. These measured signals are transmitted to the controller and protection devices, enabling real-time monitoring and automatic protective actions when abnormal conditions are detected.
Q
What is the purpose of indicator lights in a dual power supply cabinet?
Indicator lights provide a quick visual overview of the cabinet's operating status. They typically include lights for the main power supply, standby power supply, main power switch-on status, and standby power switch-on status. By observing the on/off states of these lights, operators can immediately understand which power source is active and whether the system is functioning normally.
Q
When are operation buttons and relays used in the dual power supply cabinet?
Operation buttons are used for manually switching between the main and standby power supplies, and are also essential during equipment debugging and maintenance procedures. Relays serve to convert and amplify control signals within the cabinet, enabling logical control of the circuit and ensuring smooth coordination between different components of the dual power supply system.
