Reliability Of Adapter
The adapter is an AC power source. Many electrical appliances need adapters. Just in commercial products with the name of the adapter, in fact, plainly is an AC power, Adapter in the industrial field we call the switching power supply, but the appearance of a little difference.
Standard for Adapter
1, back to safety standards EN60335, EN60950, UL60950, as/nz60950, EN61558, j60950gb4943, GB17625; Electromagnetic compatibility CISPR22, Class B, EN55022, FCC insulation grade B.
2, 19v4.75A power supply, Model: FY1904750 trademark: Fuyuang
1, stress test: Product each lead terminal can withstand axial tensile force of 2 kilograms, the duration of 60 seconds, no loose, blocking, or other damage phenomenon.
2, DROP test: products from the height of 90CM,-each direction once, Adapter fall in thickness of 1 CM Pine Board surface, no abnormalities, insulation resistance testing, the smallest 10M ohms. Refer to GB/t 4857.
3, Wire swing test: wire lifting weight 200 grams, Adapter sway angle of 120 degrees, 300 rounds still need to guide. Refer to ul-817/jisc8306.
