SPR Boosts R&D Strength for Switching Power Supplies

Founded in 2019, Suzhou Sipuri Electronic Technology Co., Ltd. (SPR) draws on its core team’s 15‑year extensive experience in the power‑supply industry and takes technological innovation as the core driving force of corporate growth. Key R&D team members possess over 10 years of hands‑on experience in switching‑power‑supply development. We conduct technical research on high‑efficiency topologies, EMC optimization and intelligent control algorithms, continuously upgrade product performance and hold multiple technical patents, laying a solid technical foundation for our five major product lines.

SPR operates a professional R&D and test laboratory fully equipped with reliability, safety and energy‑efficiency testing instruments. We follow a complete development workflow covering scheme design, sample debugging, high‑low‑temperature aging and EMC testing before mass production. Our products achieve an MTBF (Mean Time Between Failures) of ≥50,000 hours and comply with GB 20943‑2024 as well as EU ERP Class‑A energy‑efficiency standards.

Beyond standard product iterations, SPR delivers powerful ODM/OEM customisation services. We can tailor voltage, power rating, interfaces and protection grades to satisfy client requirements, and provide custom power‑supply solutions for smart home, industrial automation, medical equipment, commercial lighting and other sectors. Going forward, SPR will keep developing high‑efficiency, compact and intelligent power‑supply technologies and expand into new‑energy supporting power supplies, empowering global industrial upgrading through technical innovation.
