19. The color of the internal transformer of K9 Pro ESS

Some users may notice that the internal transformer of the K9 Pro ESS available in China is green while the one in some foreign countries is brown (those requiring the China Compulsory Certification are also green).

Since there are different certification demands in different countries/regions, the color of corresponding transformers may vary. But they have the same performance and indicators. For example, it needs the China Compulsory Certification for sales within China (while in foreign countries, it normally requires the CE or FCC).

To facilitate the production, we used different colors for the transformer. It is the same as the K9 Pro. The only difference is that we cannot see the color of the K9 Pro’s transformer from outside.
