This sample cames from winston electric , we specialized in this line for 8 years. The video will show you four keys why choose us next.

Good product is made of good components. 

First about capacitor, We use famous brand capacitor which is long life, high stability,safety and relaible. 

Second about inductance, we use strong anti-interference type which is thick copper wire, overtcurrent and high inductance. 

Third about transformer, we use model EC4045 which is PC40,vacumm dipping,heat uniformity and high strength insulation.
