MEAN WELL – SMPS & DIN Rail Power Supply
Founded in 1982, MEAN WELL is one of the world’s most trusted manufacturers of standard power supply products. Headquartered in New Taipei Industrial Park, Taiwan, the company ranks among the top 5 global DC power supply manufacturers, as reported by Micro Technology (April 2025). Unlike competitors focused on OEM/ODM models, MEAN WELL derives over 99% of its revenue from its own branded standard power supplies, reflecting a long-term commitment to quality and reliability.
Meanwell SMPS
For over four decades, MEAN WELL has engineered reliable Switch Mode Power Supplies (SMPS), DIN Rail Power Supplies, and LED Drivers that power industries across automation, lighting, communication, and medical sectors. Each MEAN WELL SMPS is designed with precise AC/DC conversion, energy efficiency, and high safety compliance — making it a preferred choice for industrial automation systems, machine control panels, and building management applications.
- AC-DC Industrial Power Supplies (Open Frame, Enclosed, and Modular)
- DIN Rail Power Supplies (Series: SDR, NDR, HDR)
- DC-DC Converters and LED Drivers
- Battery Chargers and Adapters
MEAN WELL operates five global production bases — in Taiwan, Guangzhou, Suzhou, Bangalore (India), and Kansas City (USA) — ensuring consistent production quality and rapid delivery.
This vertically integrated manufacturing ecosystem guarantees precision, reduced downtime, and trusted performance across every MEAN WELL power supply.
Company founder Jerry Lin attributes MEAN WELL’s growth not to aggressive marketing but to a culture of reliability, rational decision-making, and long-term partnerships.
The brand’s commitment to PQCDSR — Product, Quality, Cost, Delivery, Service, Relationship — defines its approach to every supplier and customer interaction. Over 65% of MEAN WELL’s sales come from partners who’ve been with the company for more than a decade.
If the CPU is the brain of a system, MEAN WELL believes the power supply is its heart. A single failure can cost more than the product itself, which is why every MEAN WELL design undergoes rigorous quality testing to ensure reliability in mission-critical applications.
