1) Electrostatic requirements:

Medical standards: Air type ± 2kV, ± 4kV, ± 8kV, ± 15kV, contact type ± 8kV (from low to high).

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

2) EFT requirements:

The medical standard is 2KV, with a frequency of 100KHz and a test voltage of 230V

The ITE standard is 1KV, with a frequency of 5KHz and a test voltage of 230V

Note: The medical national standard YY9706.102 is 2KV, with a frequency of 100KHz and test voltages of 100V and 240V

3) Harmonic requirements:

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

Standard classification

ClassA: All devices except those of ClassB, ClassC and ClassD 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 driver power supplies with a power of 5W or more must meet the harmonic ClassC requirements.
