What is the test standard in IEC 60529? IEC 60529 conformance test is a popular entrance protection test standard. Entrance protection determines the ability of the chassis to protect its contents. Entrance test is applicable to solids and liquids. The protection level is called IP code. IP is the abbreviation of ingress protection. IP grade refers to the protection grade of electrical equipment ...
Sunlight is essential for plants, because plants need to rely on sunlight for photosynthesis. We all know that sunlight is a continuous spectral light source, and plant photosynthesis is mainly carried out in the visible spectrum. With the progress of science and technology, people gradually produce the corresponding standard light source according to the continuous spectral characteristics of nat...
What is the RoHS Test? You might have heard the term in conversations about compliance RoHS, or the restriction of hazardous substances is a European Union regulation that applies to electric and electronic equipment. The manufacture of these products involves the use of substances that could harm human health or the environment. It regulates the use of some substances like Mercury, Lead, and Cadm...
What is fundamental wave？ Fundamental wave The frequency of the voltage or current that changes periodically in the power network is the fundamental wave (also known as the primary wave). The specified frequency of our power grid is 50Hz, so the fundamental wave is 50Hz. What are harmonics？ Harmonic Wave Except for the fundamental wave (50Hz) in the power network, any periodic voltage or curre...
There is no doubt that safety is a paramount concern in any industry. That’s why at LISUN, we focus on ensuring the highest level of safety in our glow wire testing products. 1． Glow wire tester application: The glow-wire tester uses simulation technology to evaluate the fire hazard caused by heat sources such as glowing components or overload resistors in a short time due to thermal stres...
Electromagnetic interference is mainly divided into radiation type interference and conduction type interference. The electromagnetic interference transmitted through space belongs to radiation type, and the electromagnetic interference transmitted to the power grid through power lines belongs to conduction type According to IEC, CISPR, GB and other EMI specifications, conducted disturbance mainly...
IEC (International Electrotechnical Commission) is the earliest international standardization organization in the world. It was established in 1906 to enhance international mutual understanding and hope that national committees can use these international standards if their own conditions permit IEC is mainly responsible for international standardization of electrical engineering, electronic engin...
Integrating sphere measurement system is the most common light color measurement equipment in the lamp industry. Its measurement results can meet the R & D and testing needs of most products. It is a more economical measurement means. Principle of Integrating sphere test system: 1. use the standard lamp for calibration, obtain the luminous flux data of the tested lamp through the coefficient...
Electricity discharge may cause electronic products such as mobile phones, electronic products remote control, smart locks, smart LED lighting systems, etc., or e -components, IC chips, LED lamp bead light source modules, etc. Essence Sudden failure causes the permanent failure and short circuit of electronic products. The potential failure can deteriorate the performance parameters of electronic ...
