EMC stands for "electromagnetic compatibility," which translates to "electromagnetic compatibility" in Chinese. Its basic definition is: the ability of a device or system to operate normally within its electromagnetic environment without causing unacceptable electromagnetic interference to anything within that environment.
Electromagnetic Compatibility (EMC) refers to the degree of interference of electronic products in an electromagnetic field.EMIThe comprehensive assessment of interference resistance (EMS) is one of the important indicators of product quality. The measurement of electromagnetic compatibility consists of test sites and testing equipment.
EMS Test Items Include:
Electrostatic Discharge Immunity
Radio Frequency Electromagnetic Field Immunity
Fast Transient Group Pulse Immunity to Electric
Surge Resistance (including lightning and voltage spikes)
Radio Frequency Field Induction Conducted Immunity
Power-frequency magnetic field immunity test
Voltage Sag Short-Time Interruption and Voltage Dip Immunity
Electromagnetic Interference
Electromagnetic interference, or EMI, refers to any electromagnetic phenomenon that, when accompanied by voltage and current in conduction or electromagnetic fields, can degrade the performance of a device, equipment, or system, or may have adverse effects on biological or material entities. EMI is also a major issue in inverter drive systems.
The EMI test items include:
Radiation Emission Test
Conduction Emission Test
Harassment Power Test
Current Harmonic Test
Power Harmonic Measurement
Blink Test
