Special attention should be paid to the selection and purchase of the constant vlotage led power supply part of the core components of LED fluorescent tube products. The relevant purchase of led driver power supply is as follows:

  1. led driver power supply needs to choose to purchase LED constant current drive power supply. In this way, a stable current can be ensured to supply the power of the LED tube.

  2. Choosing a very reliable 100w rainproof led power supply requires the cooperation of a good LED power supply manufacturer, and pre-coordination on the matching degree of the power supply and the LED lamp board, so that the 100w rainproof led power supply can get the maximum performance operation.

  3. Choosing a power supply needs to be designed with a rated working current of 16-18 mA. This is a more mature way to avoid serious heating caused by excessive working current.

   4. When purchasing a 100w rainproof led power supply , pay attention to the design of the working voltage. It is more reliable to design it to 3.125V.

5. The power supply is designed to work in series and parallel with a wide voltage and LED light panels. For example, the number of parallel LED light panels should be controlled well. It is recommended to be 6 parallel / 8 parallel / 12 parallel, and the total current is controlled at about 240 mA Is the best.

  6: In the process of choosing to buy 100w rainproof led power supply, actively coordinate with LED power supply manufacturers to deal with the relationship between LED series and parallel connection and PFC power factor and wide voltage, because these factors will determine the actual purchase cost.

  7. When purchasing an power supply, you need to communicate with the power supply manufacturer about the constant current accuracy, and ±3% is enough.

  8. power supply is divided into isolated power supply and non-isolated power supply. Choose a good power supply according to the actual situation of manufacturing led fluorescent tubes.

  9: Refer to the issue of led power supply efficiency and power factor. The two indicators of power factor and efficiency sometimes restrict each other, and are also related to the output current of the product. To improve efficiency, output as high as possible voltage and low current. The internal control standard of our company is generally 0.80-0.90 for power factor and 0.82-0.90 for efficiency. When our existing customers choose between power factor and efficiency, they generally tend to improve efficiency, and the power factor is above 0.80.

10: Pay attention to the size and configuration of the LED tube you produce and the power supply.
