CN Electronics
Standard power supplies are often limited to 110V or 220V. Our Universal Input (85-305VAC) technology ensures that equipment remains stable whether in New York, London, or rural India, where grid fluctuations are common.
Higher efficiency (up to 95%) means lower heat generation. With Active Power Factor Correction (PFC), our power supplies reduce harmonic pollution, extending the lifespan of connected industrial machinery.
Designed for mission-critical apps, including IEC60601-1 (Medical) and IEC/EN62368-1 (Industrial/ICT) certification, providing 2xMOPP isolation for patient safety.
Founded in 2006 and headquartered in Shenzhen, China, CN Electronics is a leading, technology-driven manufacturer specializing in high-precision electronics and comprehensive OEM/ODM solutions. We bridge the gap between complex hardware blueprints and market-ready products.
Our facility spans over 10,000 square meters, integrating advanced automated SMT lines with rigorous quality protocols. We don't just assemble; we optimize the entire energy conversion process.

The next generation of AC/DC power supplies will transition from Silicon MOSFETs to GaN technology. This allows for a 40% reduction in size while maintaining the same power output, critical for compact medical devices and high-density server racks.
Future SMPS will not just provide power; they will provide data. Integration of PMBus and I2C interfaces allows for real-time monitoring of voltage, current, and temperature, enabling predictive maintenance in "Smart Factories."
With global climate volatility, we are expanding our operating temperature range to -40°C to +85°C and altitudes up to 5000m. This ensures reliability in high-altitude telecom base stations and arctic mining operations.
In hospital environments, EMI suppression is vital. Our power supplies meet BF Type leakage current requirements, ensuring zero interference with sensitive MRI or life-support systems.
DIN Rail mounted solutions like the LI120 series provide stable DC power for PLC controllers and HMI panels even in the presence of massive motor-induced surges.
Compact module power supplies (SMPS) are used within 5G small cells, providing 305VAC input capability to handle "dirty" power grids in emerging markets.
Our Shenzhen production lines leverage automation to ensure consistency across millions of units.

A: Universal Input (typically 85-305VAC) ensures your product is truly global. It prevents hardware failure in regions with poor power grid stability and simplifies inventory by having one SKU for all markets.
A: Yes, our LOF and medical series meet the IEC60601-1 standards with 2xMOPP isolation and low leakage current, making them safe for direct patient-contact applications.
A: For standard models, lead times are typically 2-4 weeks. For custom OEM/ODM solutions involving specific PCB layouts, the process from prototype to mass production takes 8-12 weeks.
A: Every unit undergoes a 100% full-load burn-in test (Aging) before leaving the factory. Our MTBF (Mean Time Between Failures) typically exceeds 300,000 hours.
