How to do emc immunity test with a EMI receiver for LED power supply?

-

The following steps need to be carried out in the specified sequence in order to successfully test for EMC immunity using an EMI receiver:

  1. Install the EMI receiver and check to see that it is properly linked to the LED driver under evaluation.
  2. Choose the appropriate standard for the immunity test, then decide on the test intensity, frequency range, and mode of operation.
  3. In order to apply the electromagnetic disturbance signals to the LED driver, you may either make use of a generator that provides EMC immunity or find another source that is functionally equivalent.
  4. Keep a watch on what the EMI receiver is broadcasting and take some measurements to determine the degree of conducted emission.
  5. Conduct an analysis on the results of the measurements, comparing the findings to the parameters established by the chosen standard.
  6. It is strongly suggested that the test be executed several times utilizing a wide range of frequencies, degrees of interruption, and testing modes.
  7. In order for the LED driver to be considered compliant with the standard that was agreed upon, it must be able to demonstrate that it is immune to the effects of electromagnetic fields (EMC).

The ipx9k High Temperature Pressure Jet Waterproof Test Chamber is characterized by a waterproof grade of 9, indicating high temperature and high pressure water spraying, and spraying high temperature and high pressure water in various directions of the shell for water spraying test. In addition, k represents a function of pressurization, and under such strict conditions, its water pressure will become stronger. The ipx9 is currently a high level of waterproof protection. The IPx9 High Temperature Pressure Jet Waterproof Test Chamber is also widely used in fields such as LED lighting fixtures, display screens, household appliances industry, automobiles, and automotive accessories. At the same time, all dust and waterproof equipment can be customized according to user needs. The ipx9k High Temperature Pressure Jet Waterproof Test Chamber has four different vertical spray angles, namely 0 °, 30 °, 60 °, and 90 °, and the water pressure can reach 8000 to 10000 Kpa; Moreover, its testing r

Capacitance  refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According to its ability to accommodate charges, it is generally measured in Farads, and the international unit is Farads. Therefore, capacitors are essential components for electronics and power. The role of capacitors: Bypass capacitors and decoupling capacitors are two devices that provide energy storage for local devices. Bypass capacitors can reduce load demand, make the output of the voltage regulator smooth, similar to a small rechargeable battery, and can be discharged and charged. The decoupling capacitor can smooth the edge signals of the device, so as to prevent the input signal from being too

1 General 1.1 Scope and object This International Standard(IEC61032) specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: – protection of persons against access to hazardous parts inside the enclosure; – protection of the equipment inside the enclosure against ingress of solid foreign objects. SMT IP10T_AL The object of this International Standard is: – to bring together in one publication object probes and access probes currently specified in other standards, together with any necessary new probes;    – to guide technical committees in the selection of test sphere; – to encourage those concemed to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; – to limit the further proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particul
