In any high voltage and electrical noise system, ESD immunity is an important aspect of EMC and a key consideration in the selection of current isolation devices. ESD can penetrate the electrical isolation system It does not involve protective devices on printed circuit boards. The International Standard IEC 61000-4-2 specifies this system level immunity In the typical operation and application en...
Purpose of Integrating Spheres An integrating sphere gathers electromagnetic radiation from a source that is typically external to the optical instrument. This is done for the purpose of flux measurement or optical attenuation. Radiation that is introduced into an integrating sphere lighting system hits the reflective walls and is diffusely reflected many times. The radiation is scattered highly u...
JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization fo...
Dust chambers are a particularly effective tool for this since they may test a product or component’s ability to resist dust. Dust test chambers offer a comprehensive analysis of how dust affects machinery under adverse conditions. All the models typically make sure that the dust particles only enter the testing environment. Hence, the blowing sand test chamber ensures usual workplace operat...
Environmental test chamber is a necessary equipment for enterprises engaged in the production of electronic products. It can test and test electronic products and is an effective guarantee for the quality of ex factory products. Environmental equipment includes: 1. Climatic environment test equipment. The environmental factors simulated by climatic environment equipment are mainly the inherent en...
Electrostatic Discharge Electrostatic Discharge (ESD) is defined by the IEC as “a transfer of electric charge between bodies of varying electrostatic potential in proximity or through direct contact” in accordance with IEC 61000-4-2 standard. ESD61000-2_Electrostatic Discharge Simulator How are devices subject to electric discharge testing ESD test standards are creating a uniform and ...
Integrating sphere is a hollow sphere with white diffuse reflective material on its inner wall, which is also called photometric sphere, luminous flux sphere, etc. One or several window holes are opened on the ball wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good sphere, and its deviation fr...
A crucial piece of equipment for EMC testing is a spectrum analyzer. Spectrum analyzers with EMC-specific capabilities have become much more affordable in recent years. Spectrum analyzers offer a wide variety of parameter settings and must be set up properly. This is done in order to produce measurements as close as possible to the specifications of the particular EMC standards that apply to the p...
Lightning is a kind of discharge phenomenon between thunder clouds or between thunder clouds and the earth in nature It is characterized by high voltage, large current and short energy release time, which is very harmful Lightning will cause large-scale power cuts in the power system, large-scale burning of forests, destruction of buildings, explosion and fire in oil depots, paralysis of communica...
