Head Office

MeanWell Enterprises Co., Ltd. is one of the leading switching power supply manufacturers in Taiwan. Established in 1982, it gained ISO-9001 certification in 1994. Their product lines include AC/DC switching power supplies, DC/DC converters, DC/AC inverters and battery chargers. “Total Quality Assurance and Customer Satisfaction” are the central goals of the company.

We believe that our industry is one where reliability in long-term use, functionality and cost are all of great importance, but that it is reliability that differentiates the truly superior products. So, every product in the MeanWell range is the result of rigid procedures governing design, design verification test (DVT), design quality test (DQT), component selection, pilot-run production, and mass production. We have recently implemented a new and highly efficient computerized management system. This system allows improved administration of sales, manufacturing, purchasing, fabrication management, shipping, customer service, and quality analysis, allowing us to ensure the best CQTS (Cost, Quality, Delivery Time, Service) for our customers.

Our goal is to offer total solutions that satisfy our customer’s requirements. We have earned a good reputation based on the quality, competitive prices and punctual delivery of our products. This reputation has enabled Mean Well to enjoy an average of 28% sales growth in the past years. We have formed long-term associations with most of our customers, working together for many years, developing many treasured relationships.

We have around 4000 standard models widely used in automation, communication, medical, moving sign, and office automation fields. Our 15,000 m2 modern facility and the intelligent information management system allow us to keep enough stock for 95% of standard models, enabling prompt delivery. To meet customers’ demands, Mean Well can deliver orders ranging in size from 1 to 20,000 units. Small, medium and large quantity orders are offered through our authorized distributors, helping to save time.

If you can’t find a suitable model from our catalogue, our talented R&D team can design a custom-made power supply to meet your requirements. With over 20 years of design and manufacturing experience in the power supply industry, we offer a total solution and would like the opportunity to become your long-term power partner.

The Chinese market has shown rapid and vigorous development. Recognizing this, in 1993 MeanWell established its Guangzhou branch office and factory. This allowed us to cooperate more closer with our customers, satisfying their need for high quality products, which comply closely with customer requirements, at low cost and in a competitive manner. Our Guangzhou office retains the corporate culture of our head office, promoting quick delivery and strong after-sales service. Our experience in opening up and cultivating markets has allowed MeanWell to become both the leading brand, and synonymous with high quality, within the Chinese switching power supply market, a reputation that has ensured continuous and stable sales growth.
