Xinouhua Power
Located in the core electronic industry belt of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), Guangzhou Xinouhua Electronic Technology Co., Ltd. has established itself as an industry-leading OEM/ODM manufacturer. We specialize in the research, development, and manufacturing of high-power DC/AC programmable power supplies, custom MS Series factory power systems, and high-frequency power vector controllers.
With 1,200 square meters of state-of-the-art production space, 2 standardized high-performance assembly lines, and a core technical team of 12 electrical engineers boasting over 20 years of combined experience, we ensure compliance with international industrial benchmarks. Every piece of equipment leaving our facility passes rigorous quality assurance systems and carries the European Union's CE certification.
As a global hub for power electronics, the Guangdong-Hong Kong-Macao Greater Bay Area offers incomparable manufacturing advantages. Choosing Xinouhua as your MS Series factory partner guarantees access to a mature industrial cluster that optimizes lead times, component quality, and cost efficiency:
Proximity to major semiconductor providers, magnetic core suppliers, and high-frequency transformer factories allows us to obtain tier-1 raw materials at minimum delay and cost.
Our specialized engineering team can turn custom electrical schematics and enclosure design requirements into working physical models in a fraction of standard industry timelines.
Direct access to major international deep-water ports (Shenzhen, Guangzhou, Hong Kong) allows seamless sea, air, and express distribution to Europe, North America, and beyond.
The MS Series programmable power supplies are designed around the concept of "high power density, high reliability, and high application value." Utilizing modern high-frequency switching technology, active power factor correction (APFC), and digital DSP control, these systems deliver clean, stable, and highly programmable energy sources.

In automated test equipment (ATE) environments and long-term aging tests, power source failures can result in massive losses. Our MS Series Factory adopts several structural protections:
Guangzhou Xinouhua implements an all-link quality control system starting from substrate component verification to final load cabinet testing. Here is how our OEM production lines operate:
To meet international laboratory and safety guidelines, our factory is equipped with high-precision instruments. Every custom OEM product goes through a series of stress trials using our in-house testing arsenal:
Industrial testing equipment operates within diverse grid structures and regulatory frameworks. Providing information gain on grid compatibility and import approvals is central to our customer relationship philosophy.
Global facilities run on different standards. Our custom MS Series can be wound and configured internally to support European standard 230V/400V 50Hz, North American 120V/208V/480V 60Hz, and Japanese 100V/200V configurations. Active filtering ensures that harmonic feedback to the local grid remains well below local regulatory thresholds.
Exporting to highly-regulated regions requires strict adherence to safety standards. Our products comply with the LVD (Low Voltage Directive) and EMC (Electromagnetic Compatibility Directive), securing CE marks. For North American partners, our production protocols allow easy certification via NRTLs (Nationally Recognized Testing Laboratories) like UL and CSA.
Integrating a custom AC/DC power supply into an existing industrial PLC network or ATE rack can be challenging. Xinouhua provides software integration kits (SDKs), custom LabVIEW drivers, and Modbus command sets. We support global system integrators by providing remote code testing and on-site engineering consultations when required.
Our programmable AC and DC energy systems serve as critical infrastructure across several high-growth industries worldwide:
Testing onboard chargers (OBC), EV battery management systems (BMS), and high-voltage auxiliary motors under real-world start-stop voltage drop profiles.
Simulating solar arrays with variable irradiance curves to verify the MPPT efficiency of commercial photovoltaic micro-inverters.
Providing reliable power infrastructure to third-party calibration houses, university physics laboratories, and safety testing chambers.
The power supply industry is undergoing transition driven by digitalization, green transition, and automation. We stay ahead of these trends by actively integrating new technological parameters into our OEM designs:
Silicon Carbide (SiC) and Gallium Nitride (GaN) devices allow switching topologies to run at higher frequencies, significantly reducing the volume of copper transformers and inductors. The result is more compact rack systems, increasing power density by up to 35% compared to traditional silicon designs.
Modern testing setups require energy to flow back into the AC grid rather than being dissipated as heat. Regenerative power supplies reduce operating costs and thermal footprints, satisfying the ESG targets of global manufacturers.
