1) Static electricity requirements:

医疗标准：空气式±2 kV, ±4 kV, ±8 kV, ±15 kV,接触式 ±8 kV ，（从低往高打）。

ITE standard: air type ±2 kV, ±4 kV, ±8 kV, contact type ±4KV, (from low to high).

2) EFT requirements:

a: Medical standard is 2KV, frequency 100KHz, test voltage: 230V

b: ITE standard is 1KV, frequency 5KHz, test voltage: 230V

备注：医疗国标YY9706.102标准为2KV,频率100KHz, 测试电压：100V和240V

3) Harmonic requirements:

Power supplies with input power greater than 75W need to meet the harmonic ClassA requirements. If they are power supplies for computers, computer monitors, computer accessories, and TV receivers, they need to meet the ClassD requirements. Test voltage: IEC standard 230V, CCC standard 220V.

Standard classification:

ClassA: All devices except ClassB, ClassC, and ClassD devices are classified as ClassA devices.

ClassB: Portable tools, arc welding equipment

ClassC: Lighting equipment (LED power supply)

ClassD: Computers and computer monitors, computer accessories, television receivers

Note: LED driving power supplies greater than or equal to 5W need to meet the harmonic ClassC requirements.
