With a compact, multi-row winding that interlocks like scales, it is redefining voltage flexibility in industrial testing.
As global installed capacity of renewable energy and the scale of energy storage systems continue to expand, the demand for performance testing of core equipment such as PCS and frequency converter is experiencing explosive growth. Meanwhile, the “behind-the-scenes enabler” that ensures precise and reliable testing—the multi-voltage output transformer—is gaining increasing market attention.
The R-grade multi-voltage output transformer developed by CEEG is a power solution specifically designed for intelligent new energy testing platforms. It precisely converts the input voltage into multiple selectable output voltages, acting like a “universal key” that unlocks the testing of various devices and motors.
1. Testing Innovation: Industrial Testing Enters the Era of Voltage Flexibility
In traditional industrial testing scenarios, testing equipment with different voltage requirements meant preparing multiple dedicated transformers or using complex voltage regulation devices. Operators had to switch connections between different units, which was time-consuming, labor-intensive, and posed potential safety risks.
The multi-voltage output transformer for testing platforms has completely changed this situation. Through its unique multi-tap winding design, it enables flexible switching among five or more different voltage levels.
Operators only need to use the integrated intelligent control system to complete rapid voltage mode switching with a single command from the control room, without any on-site manual intervention, significantly improving testing efficiency and operational safety.
This design not only reduces equipment investment costs but also markedly decreases the footprint of the testing platform. In modern industrial parks where space is at a premium, equipment compactness has become an undeniable competitive advantage.
2. Technological Breakthrough: Crafting the Art of Power Conversion
The core breakthrough of this transformer lies in its innovative “single-coil, multi-row” structure. The lead-outs are arranged in layered, tightly packed rows. Behind the seemingly simple exterior, the design overcomes manufacturing challenges such as large winding radius of foil-wound coils and the coexistence of multiple foil winding methods.
In terms of insulation, the transformer adopts R-class insulating materials with a temperature resistance of up to 220 °C. Combined with a deep isolation design, this ensures stable operation even under demanding testing environments.

The cooling system is equally ingenious, featuring a hybrid solution that combines forced-air cooling with natural heat dissipation. Based on real-time load conditions, the system automatically adjusts cooling intensity, ensuring stability and reliability during long-term full-load operation.
3. Diverse Applications: Covering Full Industry-Chain Testing Needs
On the renewable energy generation side, this transformer provides multi-voltage switching test environments for photovoltaic inverters and energy storage power conversion systems (PCS). It adapts to grid standards across different countries and regions worldwide, offering strong support for the global deployment of China’s new energy equipment.
In the industrial sector, it covers a full range of testing requirements—from general-purpose motors (400 V level) to high-voltage motors (800 V level), and even heavy-duty equipment (1,140 V level). Whether for motor efficiency curve measurement or insulation performance verification, it delivers precise voltage support.
In electronic product testing scenarios, this transformer also excels. It can provide a stable multi-voltage environment for long-term aging tests of electronic components and industrial equipment, and can be integrated into automated production lines to simulate various operating voltage conditions.
4. The Future Is Here: A New Trend Toward Diversified Power Equipment
The rapid growth of new energy is profoundly reshaping the market demand landscape for power equipment. Application scenarios are expanding quickly from traditional power transmission and distribution to renewable energy generation, end-use power conversion, and various industrial supporting fields.
This diversification trend places higher demands on power equipment—greater flexibility, higher intelligence, and closer alignment with specific application scenarios. The emergence of CEEG’s multi-voltage output transformer is a direct response to this trend.
As testing requirements continue to evolve, this transformer keeps evolving as well—smarter control systems, a broader voltage range, and higher conversion efficiency. With every iteration, industrial testing capabilities are elevated.
Looking ahead, CEEG will continue to deepen its commitment to technological R&D and scenario-driven innovation, delivering safer and more reliable green power solutions for the diverse power demand market, and forging more industry-specific products with craftsmanship.
