Explore our core engineering lineup of highly stable industrial switching power supplies optimized for battery charging, high voltage testing, and EV station deployment.
Based in the global shipping hub of Shanghai, our state-of-the-art 10,000 square meter factory specializes in the research, design, and precision manufacturing of high-power regulated switching power supplies. Over the last 15 years, we have scaled our production capacity to meet the growing demands of electric vehicle infrastructure, industrial automation, and battery charging projects worldwide.
The rapid expansion of global Electric Vehicle (EV) charging networks has established an unprecedented demand for reliable, high-density power conversion hardware. At the core of every high-speed DC charging station or localized fleet hub is the AC-DC power supply module. This component is tasked with transforming alternating current from the municipal grid into stable, high-voltage direct current capable of recharging battery packs within minutes. Minimizing energy loss during this transformation requires not only high-efficiency electrical engineering but also robust thermal design to prevent system degradation over extended operation.
Power supplies for charging stations must endure severe electrical stress. Unlike standard indoor consumer electronics, industrial charging stations operate in outdoor environments characterized by fluctuating temperature extremes, high humidity, and frequent line-voltage transients. The key to maintaining a 99.9% field reliability rate lies in selecting industrial-grade topologies that incorporate power factor correction (PFC) circuitry alongside phase-shifted full-bridge or LLC resonant topologies. This balance mitigates harmonic pollution on the grid while achieving efficiency benchmarks of 88% to 89%.
EV batteries feature diverse chemistries and nominal voltages, ranging from standard 400V passenger sedan systems to the newer 800V and 1000V architecture found in heavy-duty commercial fleets and ultra-fast charging platforms. A modern manufacturing plant must produce power supplies that offer broad adjustable voltage capabilities. Our engineering solutions allow manual and computer-controlled voltage programming (e.g., adjustable ranges from 12V up to 1000V), allowing procurement officers to deploy identical hardware base configurations across diverse fleet applications.
Every industrial switching power supply we fabricate underpins 15 years of process optimization inside our 10,000 square meter Shanghai facility.
China is the global powerhouse for lithium-ion battery integration and EV infrastructure deployment. By sourcing power supplies directly from a dedicated manufacturer in Shanghai, international clients realize major strategic advantages:
Developing high-power electrical converters requires a strict balance of efficiency, protection, and cooling options. Our product catalog features solutions configured for distinct macro sectors:
Industrial charging operations cannot afford down-time. For this reason, we employ a strict double-validation protocol before any module leaves our dock. Every power supply undergoes both computer-automated performance logging and manual stress testing by certified test engineers. This rigor guarantees that our qualification rate reaches 99.9%.
Furthermore, global transportation demands robust protective structures. All international shipments are prepared with custom packaging layers:
As governments globally target transportation decarbonization, charging networks are transitioning toward modular megawatt installations. Power supply units are required to operate with wide AC input ranges, high power factor scores (exceeding 0.98), and smart control integration (such as CAN bus, RS485, or Modbus protocols). These interfaces enable real-time parameter tracking, letting operations managers scale charging performance to meet dynamic peak load limits.
