Abstract: The EFT pulse generator is a high-precision instrument specially designed for electromagnetic compatibility (EMC) immunity testing. Its core function is to simulate high-frequency fast transient pulse interference that electrical and electronic equipment may encounter in actual operation, such as pulses generated by grid switching operations, relay contact bounce, etc. It is used to eva...
Abstract: This paper takes the JL‑56 IPX5 and IPX6 Waterproof Testing Machine in the LISUN JL‑X waterproof test system as the research object. Based on the test requirements specified in GB/T 4208‑2017 *Degrees of protection provided by enclosures (IP code)*, clauses 14.2.5~14.2.6 and Figure 6, this paper analyzes in detail the hardware configuration, technical parameters and test performa...
Abstract: Lumen measurement is a core method for evaluating the photometric performance of lighting sources, which directly reflects the luminous capacity and energy efficiency level of light sources. Taking the LISUN LPCE-2 (LMS-9000) LED CCD Rapid Photometric, Colorimetric and Electrical Comprehensive Testing System (for details, please visit: https://www.lisungroup.cn/products/712.htmll) as th...
Abstract: Needle flame test equipment is a core fire safety detection device in the fields of electrical and electronic products, household appliances, lighting, and information technology equipment. By simulating the small flames generated by faults such as circuit short circuits and component overheating inside the equipment, it can accurately evaluate the flame resistance and fire safety of pr...
Abstract IPX3/4 testing for lighting fixtures represents a critical validation methodology for luminaires deployed in challenging environmental conditions. This systematic analysis examines the oscillating tube apparatus defined in IEC 60529 Figure 5, delineating the precise technical requirements that distinguish spray water protection (IPX3) from splashing water protection (IPX4). Through detail...
