As the global capacity for new energy and energy storage systems continues to expand, the demand for rigorous performance testing of core equipment—such as Power Conversion Systems (PCS) and variable frequency drives—has skyrocketed. Behind these precision tests lies an unsung hero: the multi-voltage output transformer.
CEEG is proud to introduce our latest Multi-Voltage Output Transformer, a power solution specifically engineered for renewable energy intelligent test platforms. By converting input voltage into a wide array of precise output options, CEEG is redefining industrial testing standards, offering operators true "Voltage Freedom."
1. The Challenge: Breaking the Bottleneck of Traditional Testing
In traditional industrial testing scenarios, verifying equipment with different voltage requirements often meant a logistical nightmare: deploying multiple dedicated transformers or bulky voltage regulation devices. This approach required manual switching of connections between equipment—a process that is time-consuming, labor-intensive, and fraught with safety risks.
The CEEG Solution: Our multi-voltage output transformer fundamentally changes this dynamic:
5+ Voltage Levels: Through a unique multi-tap winding design, a single unit can flexibly convert to five or more distinct voltage levels.
Intelligent Switching: Operators can switch voltage modes instantly via an integrated smart control system in the control room. This eliminates the need for manual on-site intervention, significantly improving efficiency and personnel safety.
Compact Footprint: By replacing multiple units with one, the system saves substantial capital investment and floor space—a critical advantage in modern, space-constrained industrial parks.
2. Core Innovation: The "One Coil, Multiple Rows"
The defining feature of this transformer is its structural artistry, specifically the "One Coil, Multiple Rows" architecture.
While it appears to be a sleek, uniform arrangement of lead-outs, this structure represents a significant triumph over complex manufacturing challenges. CEEG engineers have successfully overcome the difficulties of large-radius foil winding and the coexistence of multiple foil winding techniques to create this structure.
Key Technical Specifications:
Superior Insulation: The unit utilizes Class R insulation materials, capable of withstanding temperatures up to 220°C. Combined with a deep isolation design, it ensures stable operation even under the harshest testing environments.
Hybrid Cooling System: We have adopted a composite cooling scheme that merges forced air cooling with natural heat dissipation. The system automatically adjusts cooling intensity based on real-time load, ensuring reliability during long-term full-load operation.
