How to achieve one-to-three LED fluorescent tube?
Due to the special requirements of users, external power supply is required. A power supply with three LED tubes. How is it generally done?
1. Using isolated power supply, there are two situations
1. The current of the power supply is directly output, and 3 LED tubes are used in parallel, so that the current is automatically distributed to each tube. If the lamp bead current consistency is good, the current is basically the same.
2. Each channel of the power supply is output independently, which can ensure that the current of each channel is basically the same, so that the power supply is relatively stable. Even if there is a problem with one channel, the other two channels can work normally.
The advantage is that the quality is stable and the power can be larger. The price is slightly higher.
Benwei currently does both of these programs, and the effect is good
2. Non-isolated power supply can also realize the situation of one-to-three LED fluorescent tubes. Since the current of the non-isolated power supply is relatively small, efforts must be made to control the current, otherwise the power supply will not be able to drive the LED fluorescent tube. Higher requirements for lamp tubes. How to achieve it? You can consult Langte Company to solve this problem for you.
The advantage is: stable quality, good quality and low price.
The non-isolation efficiency is high, but pay attention to the connection of the line to be energized.
When replacing the grille lamp, it is cost-effective, convenient and durable.
