Introduction Voltage impulse generators, commonly referred to as Voltage Spike Generators, are crucial tools in electromagnetic compatibility (EMC) testing. These devices simulate high-energy voltage spikes or transients that electrical equipment might encounter during operation, such as those caused by lightning strikes, switching operations, or power-line crosses. Voltage impulse generators are ...
Abstract Conducted interference testing is a critical process in evaluating the electromagnetic compatibility (EMC) of electronic devices and systems. This paper provides a comprehensive analysis of conducted interference testing, focusing on the role of the LISUN EMI-9KB EMI Test Receiver in conducting EMI conducted interference tests. We explore the principles, setup, and applications of conduct...
Flammability testing plays a crucial role in ensuring the safety and compliance of electrical and electronic products. The vertical flammability test is a key method for assessing the fire resistance of various materials, particularly in electrical equipment, household appliances, and plastic components. This test is widely used to classify materials based on their flame-retardant properties, help...
Introduction In today’s rapidly evolving electrical and electronic systems, ensuring the resilience of devices against voltage dips and interruptions is critical. Voltage dips and interruptions are common disturbances in power supply systems that can have a significant impact on the operation of sensitive electrical equipment. To simulate these disturbances, high-reliability equipment such a...
Abstract The CDNE Coupling Decoupling Network is an essential tool for conducting electromagnetic compatibility (EMC) testing. By allowing precise injection and isolation of signals in compliance with international standards, the CDNE ensures reliable assessment of a device’s electromagnetic emissions. This paper focuses on the working principles, applications, and specifications of CDNE net...
Introduction Infrared thermometers, including ear and forehead thermometers, are widely used in medical and industrial applications for non-contact temperature measurements. These devices require periodic calibration to ensure their accuracy and reliability. The Blackbody Furnaces and Infrared Temperature Calibrators, such as the LISUN BBF-1 Black Body Furnace | Tachometer Calibrator, provide prec...
Abstract Gloss meters are essential instruments for quantifying the glossiness of surfaces across various industries, including automotive, paint, plastic, and ceramics. Single angle technology, particularly at a 60° measurement angle, is widely adopted for its effectiveness in assessing semi-gloss surfaces. This paper provides an in-depth analysis of single angle technology in gloss meters, with...
Introduction Corrosion is a critical challenge for many industries, particularly those working with metals and alloys. The salt spray test is one of the most widely adopted accelerated corrosion testing methods, used to evaluate the resistance of materials and coatings to corrosive environments. This article will focus on the importance of salt spray equipment, highlighting the features and applic...
The demand for high-quality lighting solutions has led to a significant focus on testing and standardizing various light sources, including energy-saving lamps, fluorescent lamps, high-intensity discharge (HID) lamps such as high-pressure sodium and mercury lamps, cold cathode fluorescent lamps, and LEDs. To ensure compliance with international standards such as CIE 177, CIE-13.3, CIE-84, ANSI-C78...
