The NB100-D-075-020 is a state-of-the-art 2-in-1 integrated drive system engineered specifically for new energy commercial vehicles, with specialized focus on electric cold chain logistics and EV air conditioning systems. This compact unit seamlessly combines a high-performance 7.5kW AC Vector Control Inverter (VFD) and a robust 2kW DC-DC Converter into a single, lightweight housing.
Designed to replace bulky, separate components, this all-in-one solution powers both the electric scroll compressor (via 0-380V AC output) and auxiliary low-voltage systems like condenser fans, water pumps, and control units (via 24V/27.5V DC output). With its wide input voltage range (400V-750V), IP67-level protection capabilities, and advanced CAN bus communication, the NB100-D-075-020 optimizes space, reduces wiring complexity, and enhances reliability in electric buses, refrigerated trucks, and specialty EVs.
Key Features & Benefits
Space-Saving 2-in-1 Architecture: Integrates a 7.5kW synchronous motor driver and 2kW isolated DCDC converter, reducing system weight by up to 30% and simplifying installation
High-Efficiency Power Conversion: Features DCDC conversion efficiency of up to 96% at 540V input, minimizing energy loss and extending vehicle range
Precise Vector Control: Utilizes SVC Open-Loop Vector Control for synchronous motors, ensuring smooth operation, high torque at low speeds, and precise frequency regulation (0-400Hz) for EV compressors
Robust Environmental Adaptability: Designed for harsh automotive environments with operating temperature range of -40°C to +75°C and comprehensive protection against over-voltage, over-current, overheating, and short circuits
Smart CAN Bus Integration: Fully compatible with ISO 11898-2 standards, allowing seamless real-time monitoring and control via vehicle BMS or central PLC systems
