Product Specifications

Product Advantages
✅ Modular Hot-swap Design
Single module can be replaced online without system power outage. N+1 redundancy improves continuous operation reliability and simplifies field maintenance.
✅ Native Compatibility with Tonhe Modules
Perfectly matched with Tonhe TH rectifiers and monitoring units. Pre-defined backplane and signal definition save secondary development and commissioning work.
✅ Reinforced Load-bearing Structure
Self-developed strengthened support frame, anti-deformation under heavy current and high-load distribution for long-term stable operation.
✅ Wide Temperature & Superior EMC Shielding
Optimized aluminum shielding cavity for strong anti-interference performance. Wide-temperature variant adapts to plateau, cold regions and outdoor cabinet scenarios.
✅ High Customization Flexibility
Slots, depth, busbar layout, fan arrangement, terminals, cutouts, silk print and logo can be adjusted per overseas project requirements. OEM service supported.
✅ High Power Density Air Duct
Independent split airflow channel for uniform heat dissipation and lower temperature rise of power modules.
✅ Standard Communication Interfaces
Reserved RS485 and Ethernet alarm ports, supporting connection to SCADA system for remote power status monitoring.
