Product Overview
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.
