How to choose the appropriate LED street light power supply
The selection of LED street light power supply (types of LED street light power supply) is crucial for the normal operation of mechanical equipment electrical control systems. When choosing LED street light power supply (knowledge of LED street light power supply), there are also various factors and key points that we need to consider. So, what aspects should we consider when choosing the power supply for LED street lights? Many people may not be aware of this. In view of this, the editor has collected and organized information to provide a detailed summary of the considerations and key points for choosing LED street light power supply.
Principles for selecting LED street light power supply (selection of LED street light power supply)
Firstly, according to the type of mechanical equipment, load torque characteristics, speed regulation range, static speed accuracy, starting torque, and usage environment requirements, it is necessary to decide which control method and protective structure of LED street light power supply is most suitable. The so-called combination refers to achieving the best cost-effectiveness of LED street light power supply application while meeting the actual process production requirements and usage scenarios of mechanical equipment.
Factors to consider when choosing LED street light power supply
When selecting speed control for LED street light power supply, it is necessary to consider various aspects such as process requirements, cost savings, and investment payback period. If only considering process requirements and cost savings, the following situations are more advantageous for using variable frequency speed regulation:
According to the process requirements, the production line or individual equipment needs to adjust the motor speed according to the program or requirements. For example, in the packaging machine conveying system, the system conveying speed needs to be changed according to different varieties of products. Using variable frequency speed regulation can make the speed control system mechanism simple, accurate, and easy to implement program control.
Replace mechanical variable speed with variable frequency speed regulation. For example, machine tools can not only eliminate complex gearboxes, but also improve racing speed and meet program control requirements.
Using variable frequency speed regulation instead of gates or baffles to adjust flow is suitable for fans, water pumps, compressors, etc. For example, the boiler water pump, blower, and induced draft fan have implemented variable frequency speed control, which not only eliminates the need for servo amplifiers, electric operators, electric actuators, and feedwater valves (or windbreakers), but also enables the entire boiler control system to achieve fast dynamic response, high control accuracy, and stability.
Key points for selecting LED street light power supply
The first point. Select an appropriate control method for LED street light power supply based on load characteristics
There are various types of LED street light power supplies available on the market today, and their functions are becoming increasingly powerful. The performance of LED street light power supplies is becoming a determining factor in their speed regulation performance. In addition to the inherent manufacturing process of LED street light power supplies, the control method used for LED street light power supplies is also very important. The following table summarizes the performance characteristics of various LED street light power control methods in recent years.
In summary, different control methods can be used for variable frequency control of asynchronous motors to obtain speed regulation characteristics with different performance characteristics.
Second point. Select the protective structure for the LED street light power supply based on the installation environment
The protective structure of LED street light power supply should be adapted to its installation environment, which requires consideration of factors such as environmental temperature, humidity, dust, acidity and alkalinity, corrosive gases, etc. This is closely related to the long-term, safe, and reliable operation of LED street light power supply.
