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...
IEC 61000-4-2 compliance test standard for electrostatic discharge immunity has voltage levels of 2,000 to 15,000 Volts. The electrostatic discharge simulators or “ESD Guns” produce voltage levels even up to 30,000 volts (for overstress ESD testing) but with current in the milliamps and is essentially not dangerous. Zapping yourself will generate a mild electrocution, less than standar...
The most of luminaires manufacturers are requested to do IK level test (Impact Protection). LISUN can supply the IK test instrument: IEC62262 Impact Protection Tester | IK07 to IK10 Pendulum Impact Hammer. IK Level Tester IK07-10 IK ratings are defined as IKXX, where “XX“ is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against exte...
Before a product is introduced to the market, EMC testing is necessary to obtain an Electromagnetic Emission and Immunity test certification. However, the cost of performing real EMC tests is high. The product needs to be tested in an EMC pre-compliance test lab before undergoing the actual EMC test. To make sure the device will pass the EMI/EMC compliance test, pre-compliance testing will replica...
The integrating sphere system is composed of spectrometer, standard light source, DC power supply, AC power supply and digital power meter, which provides the calibration of luminous flux, color temperature, wavelength, chromaticity, voltage, current and other items. Digital power meter: It is an electronic measuring instrument used to measure voltage, current, electric power, etc. Usage: it i...
