The power supply has a parameter: IP rating, that is, dustproof and waterproof rating. Use IP by two numbers to indicate, the first number indicates the solid-state protection level of the device, and the second number

Indicates the liquid protection level of the equipment. According to the different numbers of the product shell, the protection ability of the product can be quickly and conveniently determined.

  Of course, the power supply also has short-circuit, overload, and over-temperature protection parameters. This point does not need to be explained too much, it is the meaning you understand.

  Q: What are the precautions for choosing LED waterproof dimming power supply?

answer:

  A. In order to increase the service life of the waterproof constant voltage driver, it is recommended to choose a model with a 20% more output power rating. For example, if the load is 120W, it is recommended to choose a 150W waterproof constant voltage power supply, and so on can effectively improve the life of the waterproof power supply.

  B. It is necessary to consider the working environment temperature of the waterproof power supply and whether there is additional auxiliary heat dissipation equipment. The load is equivalent to increase when the ambient temperature is too high, so the waterproof power supply needs to be reduced

The amount of output.

  C, the use of street lamp power supply and conventional power supply should choose the corresponding power supply.

  D, select the required product certification and performance parameters, specifications, such as CE/PFC/EMC/ROHS/CCC certification, etc.

  Q: Why does the waterproof power supply fail to turn on smoothly when the load is a motor, bulb or capacitive load?

answer:

  When the load is a motor, a light bulb or a capacitive load, the current is too large at the moment of turning on, which far exceeds the maximum load of the waterproof power supply, so the waterproof power supply will not be able to turn on smoothly.
