What is the difference between IP Rating and NEMA Rating?
2021-11-08
Smarts manufacture mostly NEMA-4X, IP20, IP67 led power supplies, so how to choose when buying these drivers? First, we need to know the difference between the rating.

An IP (Ingress Protection) rating, which was established by the International Electromechanical Commission (IEC), a worldwide organization for standardization, is mainly used by European buyers to specify the extent of protection an electrical enclosure has against environmental conditions. The rating consists of the letters IP by two digits, the higher the number the better the protection. So that is why you can hear the sales person say to you that the IP20 LED power supply is for indoor use, while IP67 LED power supply can for indoor and outdoor use.

As for the NEMA ratings, the United States National Electrical Manufacturers Association (NEMA) also publishes protection ratings for enclosures similar to the IP rating system published by the International Electrotechnical Commission (IEC). Smarts NEMA- 4, 4X enclosures power supply equals to IP66, which can be used in dry, damp, wet locations.

So, if you are on the fence about what to identity IP20, IP67, NEMX-4X rating, now you will have a clear view of it. Smarts offer you UL/ETL listed no-filker constant voltage, constant current led driver for you to choose. Pls don’t hesitate to contact with us at info@swinpower.com.
