Description
Low-frequency transformer adopts high efficiency, low loss, environmental protection circuit design, with over-voltage protection, overload protection. The product is beautiful and elegant, the shell adopts high-temperature resistance and flame retardant, adopts ultrasonic welding, which is safe and reliable. The output interference is very small, and the output voltage is stable, which can better extend the service life of external electrical appliances.
As we all know, the minimum temperature of a low-frequency transformer should not exceed – 15 ℃, and the highest temperature should not exceed 40 ℃. Just like human beings, these two extreme temperatures are the bottom line of our contact. Therefore, we must control the temperature well. The relative humidity of the surrounding air should be less than or equal to 85%, and it should not exceed this amount. Although it is not more than 40 degrees, in this condition of heat resistance, a low-frequency transformer is the best.
