Explore our high-performance models engineered for industrial automation, security backup, and clean energy conversion.
Delivering high-reliability switching and DIN rail power solutions from the heart of China’s advanced electrical manufacturing base.
NVVV Electric Technology Co., Ltd. is a professional manufacturer specializing in the research, development, production, and sales of DIN rail power supplies and switching power supplies. Located in the vibrant industrial hub of Wenzhou, Zhejiang Province, China, our company has been serving global customers with reliable power solutions for over a decade.
With a registered capital of USD 1.4 million and annual export revenue exceeding USD 1.27 million, we have demonstrated consistent growth and financial stability. Our modern manufacturing facility covers 2,644 square meters and features 5 automated production lines equipped with 46 advanced manufacturing machines. We maintain a team of 50 dedicated employees, including 7 experienced R&D engineers who drive our innovation forward.
Innovation is at the core of our business. We release approximately 120 new products annually, ensuring our customers always have access to the latest power supply technologies. Our product range encompasses DIN rail power supplies, enclosed switching power supplies, waterproof power supplies, UPS systems, triple output power supplies, dual output power supplies, LED drivers, and pure sine wave inverters.
Engineered to power major industries with continuous efficiency, strict regulatory standards, and high reliability.
Designed for control cabinets, PLC applications, and robotics systems. Our MDR DIN rail series feature ultra-slim profiles, low ripple noise, and high efficiency to save cabinet space and minimize thermal output.
Waterproof LED drivers (like the LPV-100W-24V) provide stable constant voltage/current in extreme environments. Ideal for architectural, outdoor displays, and high-bay lighting with active power factor correction (PFC).
Our pure sine wave solar inverters (ranging from 500W to 5000W) integrate high-performance MPPT controllers and battery chargers, ensuring clean, continuous conversion for critical remote and off-grid facilities.
Developing next-generation switching topologies for high-density, eco-efficient power conversion.
Our R&D efforts focus on integrating Silicon Carbide (SiC) and Gallium Nitride (GaN) transistors. This transition enables switching frequencies up to 500kHz, allowing for 30% smaller transformer sizes and overall efficiency gains up to 96%.
Developing PMBus and CAN bus communications interfaces for our DIN Rail and industrial switching supplies. This allows systems integrators to monitor real-time temperature, voltage, current, and MTBF predictions dynamically.
Refining topologies to meet strict standby power laws (ErP Lot 6 / Green Energy guidelines), reducing passive no-load loss to under 0.15W across all models and increasing the use of recyclable composite casings.
Our 2,644㎡ advanced facility in Wenzhou uses automated production and strict quality control for high yields and on-time delivery.
Quality is never compromised. We have obtained CE, FCC, CCC, UKCA, BIS, and multiple other international certifications. Our products undergo rigorous testing at every stage of production, from raw material inspection to final product testing. We are proud to maintain a 98.6% on-time delivery rate and a 31% reorder rate, reflecting our customers' trust and satisfaction.
We serve customers across North America (20%), Eastern Europe (15%), East Asia (10%), the Middle East (6%), and many other regions. We offer comprehensive customization services including sample processing, graphic customization, logo printing, and full OEM/ODM solutions.
Step-by-step visual map of our precision assembly process.
Ensuring your systems meet local safety, efficiency, and EMC parameters worldwide.
All switching power supplies are fully certified under CE, FCC, and CCC standards to reduce electrical interference, keeping your systems running without causing noise on sensitive control lines.
Equipped with built-in OVP (Over Voltage Protection), OCP (Over Current Protection), OTP (Over Temperature Protection), and short-circuit auto-recovery, ensuring safe operations in hot, cold, or unstable environments.
Our raw materials, semi-finished components, wave soldering pipelines, and final assembly pass strict QC audits, including a 100% full-load burn-in aging process before packaging.
Custom OEM/ODM manufacturing processes tailored for high-volume distributors and industrial OEMs.
For custom voltages, outdoor IP67 chassis dimensions, unique connector terminals, and logo printing, NVVV offers a streamlined engineering flow:
Purchasing directly from NVVV in Wenzhou eliminates middleman costs and gives you direct access to the manufacturing team. Our close partnerships with top component vendors ensure stable raw material access, cushioning against international supply shocks.
This allows us to maintain consistent pricing, short lead times, and steady support for major multi-year industrial projects.
