Since the birth of the world’s first semiconductor light emitting diode in the 1960s, LED lighting has been known as the light of hope in the history of human lighting because of its long life, energy saving, rich colors, safety and environmental protection. LED is also known as light emitting diode, is a solid-state semiconductor device that converts electrical energy into visible light, ...
An immunity test called EFT Immunity Measurement (EFT61000-4) is used to evaluate how well electrical and electronic equipment performs when subjected to interference. A device is put through a number of tests to see if it can withstand fast transients like electrostatic discharge and power line transients. Verifying the laboratory’s operating parameters, examining the EFT waveform, running ...
LEDLM-80PL LED Lumen Maintenance and Aging Life Test System is designed according to IES-LM-80 and TM-21, it used to test & record the optical and electrical Maintenance for single LED or LED module, the software is based on Arrhenius model and TM-21 to calculate the LED life. The LEDLM-80PL needs to work with a GDJW/GW Series High Temperature Chamber and and DC12010 DC Power Source. LED...
What is the Surge Test? The surge (impact) immunity test is to simulate the effects of lightning strikes (indirect lightning) in nature and voltage changes caused by large-scale switch switching in power supply lines on power supply lines and communication lines. The surge test specifies two waveforms (1.2/50 μs and 10/700 μs for communication waves), with amplitudes ranging from 0.5kV to 4kV, w...
What is EMC test: EMC refers to the ability of equipment or system to operate in accordance with the requirements in its electromagnetic environment without causing unbearable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, the electromagnetic disturbance generated by the equipment to the environment during normal operat...
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...
The salt spray test standard specifies the salt spray test conditions, such as temperature, humidity, sodium chloride solution concentration and pH value, and also puts forward technical requirements for the performance of the salt spray test chamber. The salt spray test standard adopted for the same product shall be selected according to the characteristics of salt spray test, corrosion rate of m...
Testing purposes? GB/T 17626.5-2008 / IEC 6100-4-5:2005 standards specify the immunity requirements of equipment to unipolar surges (impacts) caused by switching and lightning transient overvoltages. The purpose of this part is to establish a common benchmark for evaluating the performance of electrical and electronic equipment when subjected to surges (shocks). The test methods specified in thi...
A conductive barrier entirely envelops a gadget in order to shelter it from outside interference. This is known as electromagnetic shielding. The gadget can also prevent emissions from interfering with other devices in the same area. It is an insulating method. This is because it lessens or stops the transfer of energy. In this scenario, electromagnetic energy acts as a barrier between a high outp...
