The SG61000-5 fully automatic surge generator (also called lightning surge immunity test, combination wave generator, surge current generator/surge voltage generator, combined surge voltage and current generator) . How does a surge generator work? The SG61000-5 surge generator provides a common basis for evaluating the resistance of power cords and internal connectors of different equipment to hig...
The safety of electronic devices is the most important part of the various elements that determine their quality. The safety parameters include the following parameters: AC/DC high voltage. DC high insulation resistance (or insulation resistance), grounding resistance, leakage current, pulse high voltage, pulse large current, etc. Since IEC65 Announcement《Safety requirements for mains operated e...
The electro-optical test methods allowed by IESNA Solid State Lighting Products, specifically referred to as LM-79, are jointly developed by IESN and the ANSI Solid State Lighting Committee, and the main contents include: 1. Cover luminaires including light sources and light sources used as luminaires (such as LED update products) 2. The optical test method adopts the relative measurement method...
1.Light formation 1.1 Introduction Light formation refers to the formation process of organ form structure in the plant life cycle; optical aspirations refer to the process of plant growth, development and differentiation under the conditions of light. This process occurs at any period of plant growth, from germination, nutritional growth, reproductive growth to aging death, and each stage must ac...
What is EMI receiver? Electromagnetic Interference (EMI receiver) is electronic noise that interferes with cable signals and reduces signal integrity. EMI Receiver is usually generated by electromagnetic radiation sources such as motors and machines. EMI Receiver (Electromagnetic Interference) has two types: conducted interference and radiated interference. Conducted interference refers to the cou...
EMI receiver system for EMI (Electromagnetic Interference) radiation conduction or conducted emissions testing. The EMI-9KB EMI receiver is produced by the full closure structure and strong electro-conductibility material, which has high shielding effect. Due to the new technology for the EMI Test System, it solved the instrument self-EMI problem. The test results are according to the internation...
1.Introduction It is one of the most important environmental factors required for plant growth. It is not only the energy source in the process of plant growth, but also an important signal source for plant form. The energy that plants depend on survival comes from the sun. The photosynthesis is an important biological approach to the plant capture light energy. It is one of the decisive factor fo...
LISUN’s Salt spray test chamber The Salt spray test Chamber is used to conduct salt spray corrosive tests on components, parts, electronic and electrical components, metal materials, and industrial products. The salt fog test chamber complies with the following specifications: IEC60068-2-11 (GB/T2423.17), GB/T10125, GB/T1771, ISO9227, ASTM-B117, GB/T2423-18, QBT3826, QBT3827, IEC 60068-2-52, AST...
What components are generally used in an Environmental Chamber? Thermocouple A thermocouple is a moveable device that measures temperature. Product temperature control maximizes stress on the product through the chambers using a thermocouple. Airstream Control vs. Temperature Control The air temperature at the air supply’s outlet source is measured through air stream control. On the other ha...
