We are surrounded by a variety of electrical products in our daily lives. EMC (electromagnetic compatibility) refers to the ability of various electronic and electrical devices to coexist with each other without causing electromagnetic interference to other devices, and the ability to withstand electromagnetic interference from other devices and still operate normally. EMC testing is a test used to confirm and guarantee electromagnetic compatibility. In the manufacturing process of various manufacturers, EMC testing must be conducted to prevent malfunctions or defects at the user's site after the product is released.
Introduced here are the products of Noise Laboratory, whose testing equipment for electrical noise have been implemented all over the world, both in Japan and abroad. Together with Mr. Nakamura and Mr. Solomin of the company, we will introduce its features and strengths.
Noise Laboratory supporting the world's best products with EMC testing systems
The reason why Japanese products are said to be of high quality is that they undergo high-level quality verification tests. EMC testing is absolutely necessary in the production of electronic and electrical products, and demand for this testing is increasing in Thailand as well
"We have been working on the development of noise testers since around 1970, when the existence of EMC testing was not yet recognized. We provide testers that comply with international standards such as EMC and ISO," says Mr. Nakamura of Noise Laboratory.c
The company is committed to quality and is a manufacturer of highly reliable EMC testers. Here are three of its products especially recommended for the Thai market.
1) Electrostatic discharge simulator
It is an EMC tester used to evaluate the resistance of electronic devices to electrical discharge of energy charged by the human body or other objects, and can be used to evaluate device malfunction and performance. This tester has been used in quality control, design, and development of all kinds of electrical products and components, and further testing needs are expected to increase in Thailand, where the development of EVs is progressing.
＜Product features＞
・Precise electrical waveform based on the international standard
・High test reproducibility
▲ Precise electrical waveform image based on the international standard
・Pre-start inspection function (pre-check function) to check the operation of the tester before the test
・Lightweight discharge gun with optimized center of gravity balance
・Proven track record of implementations in a wide range of industries for both components and finished products
⇒ Automobiles, home appliances, machine tools, industrial equipment, electronic devices such as smartphones, etc.
2) Electromagnetic field visualization system (EPS)
Currently in Thailand, many people use spectrum analyzers to acquire and analyze electromagnetic wave data, but the customers’ feedback reveal that it is actually time-consuming and troublesome to analyze the data. This system visually displays electromagnetic wave data by color-coded mapping, making it easy to check, record, and analyze weak points and areas for improvement in products, leading to a shorter and more efficient development process.
▲ Objects of various sizes can be measured by changing the electromagnetic field probes
＜Product features＞
・Three-dimensional display (frequency, level, time)
・Capable of measuring objects of various sizes from small to large
・Compact size with high measurement flexibility
・Measurement results are mapped in color for easy understanding
・Continuously evolving through improvements and version upgrades
3) Impulse noise simulator (INS)
This tester evaluates the resilience of electronic devices by simulating rapid-rising high-frequency noise caused by switching noise and arc discharges generated by electronic motors. A wider range of frequency components and variable energy volume that exceed the requirements of international standards allow for more stringent testing.
＜Product features＞
・High originality and close to being the only product of its kind in Japan
・Selected as one of the standards by the Japan Electrical Manufacturers' Association
・Stricter testing than international standards allows for more effective development and design.
・A tool that can reproduce defects that occur at the end-user's site at the testing stage.
・Wide range of customers’ implementations in Japan, and the rising number of implementations in the international market.
Nihon Denkei x Noise Laboratory strengthen cooperation in Thailand, where demand for noise testing is growing
A private exhibition was recently held by Nihon Denkei in Thailand, and Noise Laboratory was also invited to participate.
