LED street light power is the driver that determines the LED street light. Let's take a look at what LED street light power is!

The choice of LED street light power supply (the type of LED street light power supply) is crucial for the normal operation of the electronic control system of the mechanical equipment. When choosing the LED street light power supply (LED street light power knowledge), the factors and points we have to consider are also multifaceted. So, in the selection process of LED street light power, we have to consider those aspects? Many people may not understand this. In view of this, Xiao Bian made a detailed summary of the considerations and selection points of selecting LED street light power by collecting and collating data.

LED street light power supply selection principle (LED street light power supply optional)

First of all, according to the type of mechanical equipment, load torque characteristics, speed range, static speed accuracy, starting torque and the requirements of the use environment, then determine which control method and protection structure LED street light power supply is most suitable. The so-called combination is to achieve the best cost performance of LED street lamp power supply application under the premise of meeting the actual process production requirements and use occasions of mechanical equipment.

LED street light power supply needs to be considered

In the choice of speed control of LED street light power supply, it is necessary to consider from the aspects of process requirements, cost saving, investment recovery period, etc. If only from the process requirements, saving benefits, the following several conditions are more advantageous:

According to the process requirements, the production line or single equipment needs to adjust the motor speed according to the procedure or according to the requirements. For example: packaging machine transmission system, according to different types of products, it is necessary to change the system transmission speed, and use the frequency conversion speed regulation to make the speed control system mechanism Simple, control-accurate, and easy to implement program control.

Using variable frequency speed control instead of mechanical shifting. For example, the machine tool can not only save the complicated gear transmission, but also improve the racing speed and meet the program control requirements.

The use of variable frequency speed control instead of using gates or baffles to adjust the flow rate is suitable for fans, pumps, compressors, etc. For example: boiler water pump, blower, induced draft fan implements variable frequency speed control, which not only eliminates the servo amplifier, electric operator, Electric actuators and feedwater valves (or windshields), and the entire boiler boiler control system has a fast dynamic response, high control accuracy and stability.

LED street light power supply selection points

The first point. Select the appropriate control mode LED street light power supply according to the load characteristics.

Nowadays, there are many kinds of LED street lamp power supplies sold on the market, and the functions are also increasingly powerful. The performance of LED street lamp power supply has become the decisive factor of the speed control performance. In addition to the "innate" conditions of the LED street lamp power supply manufacturing process, It is also very important to control the LED street light power supply. The following table summarizes the performance characteristics of various LED street light power control methods in recent years.

In summary, the asynchronous motor variable frequency control uses different control methods to obtain the speed regulation characteristics of different performance characteristics.

Second point. Select the protective structure of the LED street light power supply according to the installation environment.

The protection structure of the LED street lamp power supply should be adapted to the installation environment. This should consider environmental temperature, humidity, dust, pH, corrosive gas and other factors, which is related to the long-term, safe and reliable operation of the LED street lamp power supply.
