Wiring requirements: The cable is exposed to the magnetic field at a distance of 1 meter.
The cables between the surfaces of the object should be arranged as follows
If the wiring length required by the product specification is less than or equal to 1m, the test should be carried out according to the specified length. If the specified length is greater than 1m, or there is no specification, the cable length should be selected according to the typical installation method. Unless otherwise specified above, the length of the cable exposed to electromagnetic fields in the vertical or horizontal direction shall be at least 1m of cable.
2. Power frequency magnetic field immunity test
Power frequency magnetic field can have different degrees of impact on various electrical and electronic equipment, and power frequency magnetic field immunity is used to evaluate the magnetic field immunity performance of household, commercial and industrial electrical and electronic equipment in power frequency (continuous and short-term) magnetic field.
According to Standard
EN 61000-4-8；IEC61000-4-8；
GB/T 17626.8
Maximum range
1000A/M
3. Conduction harassment immunity test
Conducted disturbance immunity test of radio frequency field sensing
Evaluate the immunity of electrical and electronic equipment to conducted disturbances induced by radio frequency fields.
According to Standard
ENIEC 61000-4-6;IEC61000-4-6;GB/T17626.6
Maximum range
20V
4. Electrostatic discharge immunity test
Evaluates the immunity of electrical and electronic equipment to electrostatic discharge directly from the operator and to adjacent objects.
According to the standard
EN 61000-4-2;
IEC 61000-4-2;
GB/T 17626.2
Maximum test level
Contact discharge 30KV, air discharge 30KV
5. Three-in-one integrated system Test
A: Immunity test for voltage sag, short interruption and voltage change
Evaluate the immunity of electrical and electronic equipment to voltage stagnation, short-term interruptions, and voltage changes.
According to Standard
EN IEC 61000-4-11;IEC61000-4-11;GB/T 17626.11
B: Electrical fast transient pulse group immunity test
Evaluate the performance of electrical and electronic power supply ports, signals, and control ports under repetitive fast transient interference. Verify the immunity of electrical and electronic equipment to various types of transient harassment such as those from switching transient processes.
According to Standard
EN 61000-4-4;IEC61000-4-4;GB/T17626.4
C: Surge (shock) immunity test
Evaluates the immunity of electrical and electronic equipment to surges (shocks) caused by switching and power-demanding transient overvoltages.
According to Standard
EN 61000-4-5;IEC61000-4-5;GB/T 17626.5
6. Harassment power test
It is generally believed that when the frequency exceeds 30MHz, the harassing energy is transmitted to the disturbed device through radiation.
Experience shows that harassment energy is mainly radiated through the part of the power supply line and other deficit lines near the appliance.
According to Standard
EN IEC 55014-1,IEC 55014-1,GB 4343.1
