FAQ when choosing a rainproof power supply
1) The selection of the rainproof power supply requires the appropriate input voltage, specification model;
2) Select the appropriate output power. In order to better improve the service life of the power supply, models with 30% more power rating can be used.
3) Consider the load characteristics. If the load is a motor, a light bulb or a capacitive load, the current is very large when it is started, and a suitable power supply should be used to prevent the load. If the load is a motor, the voltage reverse flow should be considered during shutdown.
4) In addition, the working temperature of the power supply and whether there is any additional auxiliary cooling equipment need to be considered. The power supply needs to derate the output when the ambient temperature is too high. A plot of the derating curve of ambient temperature versus power.
