Explore our high-performance open frame components, medical power supplies, and multi-protocol smart chargers. Manufactured in our state-of-the-art facility to meet global compliance regulations.
Empowering global tier-1 brands, system integrators, and industrial developers with stable power topologies.
Within modern electrical equipment design, Open Frame Switching Power Supplies serve as the vital operational backbone for industrial automation, clinical medical instruments, network systems, and consumer electronics. Unlike enclosed power modules, open frame configurations feature an unshielded circuit board layout that maximizes heat dissipation through natural convection, reduces net weight, and provides seamless spatial integration into compact internal cabinets.
For procurement directors, engineering heads, and hardware architects, purchasing directly from a vetted manufacturer is critical. System stability depends on strict parameters: low leakage current, minimum electrical interference (EMI), stable output ripple, and broad thermal operating margins. As energy efficiency regulations tighten (such as DoE Level VI and CoC Tier 2), our engineering team utilizes high-density topologies to minimize loss, guarantee reliable MTBF metrics, and maintain strict adherence to international safety standards.

Our commitment to R&D drives the development of next-generation power supply technologies.
Modern power electronics require higher efficiency in smaller form factors. FuYun (RUIYU) Technology focuses on three core design directions:
Quality and reliability backed by international safety and performance standards.
With an established market share of 60% in the United States and European Union, and expanding operations in China, Japan, and South Korea, FuYun (RUIYU) operates under international quality systems. In 2012, we completed comprehensive certifications, ensuring our adapters and open frame units meet safety standards globally: UL, CUL, TUV, GS, CE, CCC, KC, and PSE.
Our quality control program covers every stage of production. Standard Operating Procedures (SOP) are strictly enforced, with 30 QA/QC specialists testing each product at every assembly phase. We conduct 100% full-load burn-in tests and electrical safety checks before packaging to guarantee defect-free delivery. We also archive detailed production records for years to ensure traceability for every unit shipped.
