Founded in 1982, MEAN WELL is one of the world’s few manufacturers dedicated to standard power supply products. It is ranked the 3rd in global power supply (DC output) makers according to a report by Micro Technology released in March, 2023. 99% of MEAN WELL sales are of standard power supply products sold under the MEAN WELL brand name.
The other two companies’ products are ODM/OEM.
MEAN WELL has been working as a “reliable partner” with customers, suppliers, contractors, and employees to build long lasting mutual trust relationships based on the spirit of “good intentions.”Thanks to robust partnerships with 245 plus authorized distributors around the world, MEAN WELL has been growing and getting stronger for four decades.
A range of electronic components, including semiconductors, are used within electronic products such as industrial and consumer equipment. Semiconductor devices such as IC, FET, transistors, diodes, etc. operate based on a stable DC power supply. In other words, it is vital to convert the AC current supplied to plants and households into a stabilized DC current.
COSEL’s DC-stabilized power units help to realize this.In particular, COSEL’s “switching power supply,” which utilizes the high-speed switching effect of semiconductors, is one of our major products. Switching power supplies are compact, lightweight and highly efficient, which means that they are now used in almost all electronic devices, including in information communications, medical and factory automation devices. We have been engaged, furthermore, since 2005, in the production of a noise filter that protects electronic equipment from a range of noise, and have now released a product using that technology.
