NB100-D-055-015-PC 4-in-1 Integrated EV Power System | Smart Controller with DCDC, VFD, PTC & CCU for Electric Buses & HVAC

Product Overview

The NB100-D-055-015-PC is a cutting-edge 4-in-1 integrated electric vehicle power system designed to streamline the architecture of new energy buses, electric coaches, and high-performance HVAC systems. This ultra-compact unit seamlessly integrates four critical components into a single robust housing: a 5.5kW DC-AC Inverter (VFD), a 1.5kW Isolated DC-DC Converter, a high-power 24kW PTC Heater, and an intelligent CCU (Central Control Unit).

By consolidating these functions, the NB100-D-055-015-PC eliminates the need for multiple separate controllers, significantly reducing wiring harness complexity, saving valuable installation space, and lowering overall system weight. Engineered for water-cooled units and energy storage applications, it features IP67 protection and natural convection cooling, ensuring silent, reliable operation in harsh outdoor environments while delivering precise control for compressors, fans, pumps, and cabin heating.

Key Features & Benefits

• Ultimate Integration (4-in-1 Architecture): Combines Traction/Compressor Drive (5.5kW), Auxiliary Power (1.5kW DCDC), Cabin Heating (24kW PTC), and System Logic (CCU) into one device. This reduces component count by ~75% compared to discrete systems.
• Silent Natural Cooling & IP67 Protection: Designed with advanced thermal management for fan-less natural cooling, eliminating noise and mechanical failure points. The IP67 rating guarantees dust-tight and water-immersion resistance, ideal for roof-mounted or under-chassis installations on electric buses.
• Intelligent CCU & CAN Bus Networking: The built-in Central Control Unit (CCU) acts as the brain of the system, coordinating the inverter, DCDC, and PTC modules. It supports standard CAN 2.0B/J1939 protocols for real-time data exchange with the vehicle BMS, enabling smart diagnostics, remote monitoring, and adaptive load management.
• High-Power Fast Heating: Integrates a massive 24kW PTC heating element, providing rapid cabin warm-up in extreme cold climates (-40°C), ensuring passenger comfort and defrosting efficiency without needing a separate heater controller.
• Versatile Motor Compatibility: The 5.5kW inverter section supports both synchronous and asynchronous motors with vector control, making it perfect for driving electric scroll compressors, water pumps, and oil pumps in complex thermal management systems.
