What FINE POWEREX does

FINE POWEREX CO., LTD. is a privately held Korean manufacturer of Switching Mode Power Supplies (SMPS) headquartered in Gunpo, South Korea, and founded in 2006. The company designs, manufactures, and sells AC/DC power converters across six proprietary product series — FPS(K) (high-reliability waterproof IP67/IP65 LED converters), FOS (economical waterproof), FWS (industrial single/dual/triple output), FLS (resonant-converter industrial), FES (economical industrial), and a Bracket accessory line — plus ODM/custom power supplies for medical and industrial OEMs. Underlying technology is built on resonant converter topologies (LLC with ZVS/ZCS soft switching), active power factor correction, synchronous rectification, and PWM feedback control, yielding efficiencies up to 95% and operating ranges of -40°C to +70°C with 5-year warranties on flagship lines.

The company serves three primary vertical segments: LED lighting (waterproof power for outdoor street lighting, signage, and display panels), industrial manufacturing (factory automation and equipment power), and medical equipment (custom ODM power supplies for devices such as Ceragem massage chairs). Revenue is generated through one-time hardware sales to distributors, direct customers, and ODM partners. The certified regulatory base — KS, ISO 9001, and approximately 100 product certifications across UL, KC, CE, and CB — constitutes the principal barrier to entry and supports sales into safety-critical end markets. The company sources distribution through two official Korean distributors, Powernet in Anyang and IYEON CO., LTD in Seoul, alongside a nationwide agent network; international sales are managed directly by a Global Marketing Manager.

FINE POWEREX pursues growth through product line diversification, ODM customization for anchor customers including Ceragem and Dilli, and selective international expansion demonstrated by participation in LED China 2016 and VISCOM Düsseldorf 2017. The company secured its first disclosed institutional capital from Hi Investment Partners in January 2019. Pricing is not publicly disclosed, and no revenue figures are available; the firm operates as a focused niche specialist rather than a high-volume commodity supplier.
