1. Electromagnetic Compatibility (EMC)

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; degree of immunity, ie electromagnetic susceptibility.

EMC includes two parts: EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference is the electromagnetic noise generated by the machine itself in the process of performing its due functions that is not conducive to other systems; and EMS refers to the machine. The ability to perform its intended function independently of the surrounding electromagnetic environment.

2. Electromagnetic Compatibility EMC Inspection Items

1. Electromagnetic emission (EMI) inspection items:

Conduction (CE) (150kHz～30MHz)

Magnetic field radiation (9KHz-30MHz)

Intermittent interference voltage (150kHz, 500kHz, 1.4MHz and 30MHz)

Power radiation (30MHz～300MHz)

Space radiation (30MHz-1GHz)

Harmonic current and voltage fluctuation and flicker (2-40th harmonic)

2. The inspection items of electromagnetic immunity (EMS) are:

Electrostatic discharge immunity

Radiated electromagnetic field (80MHz～1000MHz) immunity

Electrical fast transient/burst immunity

Surge (lightning strike) immunity

Immunity of injected current (150kHz～230MHz)

Voltage dips and short interruptions immunity

Power frequency magnetic field

3. EMC confirms the inspection report standard

4. the EMC confirmation inspection report processing process

1. Test consultation

2. Business quotation

3. Fill in the test order (provide product information)

4. Send samples or send samples to An Magnetics testing

5. Open a case

6. Execute the test

7. Issue a test report

8. Send report invoice or completion statement

9. Return samples or keep samples for 15 days (destruction overdue)

5. the implementation of electromagnetic compatibility EMC confirmation test

Confirmation inspection items are generally carried out in accordance with the inspection items specified in the national standards, industry standards or the supplier's enterprise standards for the key components and raw materials; when the factory or the supplier itself does not have the capability for relevant inspection items, regular confirmation inspections can be carried out. Entrust a laboratory organization with relevant qualifications to carry out.
