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...
EMC test is the full name of electro magnetic compatibility. It refers to the comprehensive evaluation of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products. It is one of the important indicators of product quality. The measurement of electromagnetic compatibility is composed of test sites and test instruments Today, almost all lighting applic...
How Does Test Chambers Work? Different systems are used in test chambers to create and maintain the ambient conditions depending on their intended use. Since they are frequently encountered, we’ll quickly discuss cooling, heating, humidity, and salt spray done by LISUN environmental chambers. Cooling & Refrigeration Test chambers have the capacity to regulate very low temperatures (lik...
The enclosure protection is divided into two parts. The first part is to prevent access to dangerous parts and solid relics, and the second part is to prevent water from entering. Here introduces ip5x dust proof test and ip6x refers to dust tightness test to prevent solid from entering. Dust penetrates into the product, and its effects on the product include: 1. Invade seals and housings; 2. Cha...
