Through independent R&D and design, our company has the industry's first-class fully automated production line, magnetic latching relay testing equipment, and product electrical life test bench. After more than ten years of development, the magnetic latching relays, shunts, mutual inductors and supporting smart meter cases independently developed, designed and produced by Face Electric are distributed in various countries at home and abroad. The company has successively passed ISO9001 system certification and ISO14001 environmental standard certification. The company's products have obtained UL, C-UL, CQC, VDE certification, and meet the requirements of the EU ROHS directive, and have a number of national appearance patents and utility model patents.
Yueqing Feisi Electric Co., Ltd. (Brand: FACE) was established in 2011 in Liushi, Yueqing, Zhejiang—China's "Capital of Electrical Appliances"—and expanded with a state-of-the-art production base in Shangrao, Jiangxi in 2016. We are a high-tech manufacturer specializing in the R&D and intelligent production of magnetic latching relays, customized latching relay assemblies, precision current transformers, and shunt sampling resistors. We operate a fully integrated, in-house production model across the entire supply chain, utilizing automated cleanroom production lines and advanced testing systems.
FACE focuses on four core product lines: magnetic latching relays (16A–200A), customized latching relay assemblies (integrated with bases, terminals, or shunts), precision current transformers (accuracy classes 0.1–0.5), and high-precision shunt resistors. Our products are widely designed for smart grids, EV charging infrastructure, automotive electronics, and industrial automation. In 2025, we launched a new series of highly reliable AC contactors offering superior cost-effectiveness.
Fully In-House Manufacturing: Mould development, metal stamping, plastic injection moulding, and coil winding — all under one roof ensures absolute quality & lead-time control.
Robust Quality Standards: CQC, CE, RoHS certified and dozens of technical patents.
Flexible Capacity: High-speed automated assembly lines for mass production while agile for small-batch OEM/ODM customization.
Strict Quality Control: 100% factory electrical parameter testing and reliability screening (shock, thermal cycling, ageing) guarantee industry-leading low defect rate ≤0.3%.
Our components are widely used in residential & industrial smart meters, IoT remote telemetry units, NEV low-voltage electronic control modules, DC EV fast chargers, solar PV inverters, residential energy storage units, industrial automation power distribution, and smart home appliances.
Traditional magnetic latching relays often suffer from factory defect rates of 1.5%–3% leading to contact erosion or coil failure. The FACE Difference: By implementing fully automated manufacturing and a 100% powered 48-hour burn-in/ageing test, we control our factory gate defect rate to ≤0.3% and long-term field return rate ≤0.15% — less than one-fifth of the industry average.
We provide rapid shipping for standard products, dedicated R&D engineering support for customized projects, 100% pre-shipment quality inspections, and hassle-free FOB Ningbo/Shanghai logistics. For custom requirements, we handle the entire lifecycle — from mould development and rapid sample prototyping to small-batch pilot runs and mass production — significantly shortening clients' time-to-market.
For an Australian smart grid project requiring a custom AC contactor, we provided end-to-end engineering support from technical drafting to final production. This one-stop customization shortened the customer's development cycle and reduced overall procurement costs by 25%.
We maintain long-standing strategic partnerships with numerous globally renowned smart meter manufacturers and Tier-1 automotive component brands, with over a decade of deep involvement in the international B2B component supply chain.
Our premium components are exported to over 50 countries and regions worldwide, with a strong presence in Europe, Southeast Asia, the Middle East, and North America.
Led by founder Mr. Luo Kunshui, a respected pioneer in China's magnetic latching relay industry with over 20 years of experience. At age 25, he served as Chief Engineer at Sanyou Union, and at 30 as Latching Relay Project Manager at TE Connectivity (Tyco Electronics). He founded FACE at 35, bringing global-brand engineering rigor. Our core R&D team includes four senior engineers with over a decade of specialized experience.
Mr. Luo independently developed an integrated relay assembly design that set a new benchmark for reducing defect rates in the smart grid industry.
