EMC certification has begun in China. The State Administration for Exit Inspection and Quarantine has taken the lead in conducting mandatory electromagnetic compatibility testing on six imported commo
Currently, international EMC standards are mainly represented by ISO and IEC standards. The full name of ISO is International Organization for Standardization, which is an internationally renowned sta
RS-485 bus has the advantages of simple structure, long communication distance, high communication speed, and low cost, and is widely used in industrial communication, power monitoring, instrumentatio
Artificial power supply network, also known as power impedance stabilization network, is an important electromagnetic compatibility testing device, mainly used to measure the continuous disturbance vo
In EMI testing, it is often difficult to measure the saturation characteristics (overall or partial) of the common mode coil core. Through a simple test, we can see that the attenuation of the common
EMC testing begins with connector cables. EMC testing is the measurement of electronic products. EMC standards not only specify the test levels of various electronic products, but also specify test me
The electrical fast transient pulse group test is of typical significance for detecting the anti-interference degree of equipment. Because the rising edge of the electric fast pulse test waveform is v
The causes of lightning surge are switching transients and lightning transients in the power system; The purpose of the surge immunity test is to establish a common benchmark to evaluate the performan
