There are many types of LED switching power supplies, and the quality and price of various power supplies are very different, which is also one of the important factors affecting product quality and price. So what is the difference between rainproof led power supply 400w and driving power supply?
LED driver is also a kind of switching power supply, but it has several special features and is also the commonality of this type of switching power supply, so it is customary to classify it as LED driver.
1. Its voltage output is a multiple of 3.2, but generally does not exceed 25.6V at most. Because after this number is exceeded, when the LED is turned on, there will be a possibility of instantaneously burning the last LED that is turned on due to poor product consistency.
2. It generally does not require isolation, because many products are similar in structure to ordinary lighting, and can be similar to lighting in terms of safety. Because some drivers still need to be isolated.
3. Its start is soft start. Since the consistency of the LED is very poor, and the activity of the internal PN junction changes instantaneously when it is turned on, the drive of the LED is generally designed to be soft-started to avoid this defect.
