DC output ranging from 50Vdc to 750Vdc, with constant power operation spanning 400Vdc to 750Vdc. Compatible with the full spectrum of battery packs from low-speed electric vehicles to heavy-duty logistics vehicles, enabling 'one module for multiple vehicle types' charging compatibility.
Efficiency ≥95% across the entire load range, significantly outperforming industry standards. Standby power consumption <9W. Wide AC input range of 260Vac–530Vac adapts to global grid environments. Three-phase design without a neutral line simplifies wiring and reduces system costs.
High power density with compact dimensions to save space within charging stations. Dual DSP fully digital control architecture enables damage-free hot-swapping, battery backflow protection, and intelligent discharge functionality. Automatic residual charge discharge enhances system safety.
Operates across a wide temperature range of -40°C to +75°C, with intelligent derating above +55°C. Features an innovative triple-protection design resisting salt spray, moisture, and mould — suitable for harsh coastal and high-humidity environments. Minimal electromagnetic radiation and interference.
