Xinouhua Power
Engineered for excellence, certified for global industrial standards.
In the era of Industry 4.0, measuring instruments and high-power density power supplies have transitioned from simple laboratory tools to the foundational infrastructure of global technological advancement. As a leading China top measuring instrument manufacturer, we recognize that the global market is currently undergoing a massive shift towards electrification, digitalization, and extreme precision.
The global test and measurement market is projected to reach USD 35.5 billion by 2028. This growth is driven by the explosive demand for Electric Vehicles (EVs), renewable energy integration, and aerospace innovations. Measuring instruments—specifically programmable AC/DC power sources—are critical for validating battery management systems, simulating grid stability, and ensuring the safety of airborne electronics. As an exporter based in the Guangdong-Hong Kong-Macao Bay Area, Xinouhua sits at the epicenter of this industrial evolution, bridging the gap between high-volume manufacturing and high-precision engineering.
Leveraging Wide Bandgap (WBG) materials like SiC and GaN to reduce instrument footprint while increasing output efficiency to over 95%.
Moving beyond physical dials to programmable interfaces (RS232, RS485, LAN) that allow for automated cloud-based testing sequences.
Integration of IoT sensors within power supplies to provide real-time predictive maintenance and remote diagnostic capabilities.
Guangzhou Xinouhua Electronic Technology Co., Ltd. is located in the core electronic industry belt of Guangdong, Hong Kong and Macao Bay Area, focusing on the R & D and manufacturing of high-power DC power supply. The company has 1200 square meters of modern production space, equipped with 2 standard production lines, and a core technical team of 12 people; 20 years of industry experience, strictly following international standards, and the products have passed the EU CE certification, building a full-link quality management from research and development, production, and testing System to ensure the excellent performance, safety and stability of each power supply.
Our core product philosophy revolves around "high power density, high reliability and high application value." We provide accurate test support and high stability power system solutions in automotive electronics, electric motors, photovoltaic new energy, third-party testing laboratories and other fields.






Our instruments are designed to meet the specific "Semantic Intent" of various industries. For instance, in the Aerospace sector, a "400Hz Power Supply" isn't just a number—it's a critical requirement for simulating aircraft ground power systems. In Automotive electronics, variable frequency sources are essential for simulating battery fluctuations during cold starts.
Simulating solar panel output characteristics (I-V curves) to test the efficiency of PV inverters and energy storage systems (ESS).
High-current, high-voltage stable DC sources for long-duration stress testing of electronic components, ensuring zero-defect delivery.
Ultra-low ripple programmable sources that provide the "clean" power necessary for high-resolution measurement of semiconductors.








Common inquiries from global procurement managers and engineers.
A: China, specifically the Pearl River Delta, offers an unmatched supply chain ecosystem. This allows manufacturers like Xinouhua to integrate high-end components with rapid prototyping, resulting in instruments that meet global standards (CE/UL) at a significantly higher performance-to-cost ratio.
A: 400Hz is the standard frequency used in aircraft, spacecraft, and naval vessels because it allows for smaller and lighter transformers and motors. Our frequency converters are engineered to simulate these environments with extreme precision for ground testing.
A: Yes. All our high-end programmable sources feature RS232/RS485 and optional LAN interfaces, supporting SCADA and LabVIEW integration for fully automated testing cycles.
A: Every unit undergoes a rigorous 72-hour full-load aging test on our specialized racks before shipment. Our ISO-compliant facility in Guangzhou ensures each product exported to Europe or North America maintains consistent performance under diverse environmental conditions.
