Differences between medical and ITE EMC standards:

1) Static electricity requirements:

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

ITE standards: air type ±2 kV, ±4 kV, ±8 kV, contact type ±4KV, (hit 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

Note: Medical national standard YY9706.102 standard is 2KV, frequency 100KHz, test voltage: 100V and 240V

3) Harmonic requirements:

Power supply with input power greater than 75W needs to meet the harmonic Class-A requirements. If it is a power supply for computers and computer monitors, computer accessories, and TV receivers, it needs to meet the ClassD requirements. Test voltage: IEC standard 230V, CCC standard 220V.

Standard classification:

Class-A: All devices except ClassB, ClassC, and ClassD are classified as ClassA devices

Class-B: Portable tools, arc welding equipment

Class-C: Lighting equipment (LED power supply)

Class-D: Computers and computer monitors, computer accessories, TV receivers

Note: LED driver power supplies greater than or equal to 5W need to meet the harmonic Class-C requirements.
