Key Features
- Intelligent Design
Digital current sharing technology improves both current sharing accuracy and anti-interference performance. Module sleep and rotation technology optimizes system efficiency and reduces ineffective energy loss. Multi-mode charging with real-time monitoring enables smart interaction, suitable for remote operation and diverse user demands. - Comprehensive Safety Protection
Air-isolated and lightning protection design blocks grid surges and provides dual-layer protection for the device. Full-process monitoring responds instantly to charging abnormalities. The hot-swappable module structure guarantees operator safety during maintenance. - Energy Saving & Low Noise
Three-phase PFC topology achieves PF > 0.99 and THDi ≤ 5%, with excellent grid compatibility. Full-bridge phase-shifted soft switching cuts high-frequency switching loss and standby power consumption. Intelligent noise reduction with dual electromagnetic and structural damping ensures quiet operation. - High Efficiency & Easy Deployment
Silicon Carbide (SiC) MOS modules feature high power density and redundancy design for reliable performance. Ultra-wide voltage output covers 99% of EV models for multi-scenario applications. The all-in-one structure supports fast deployment even in space-limited sites, minimizing operation costs.
