Features:
- Routes PPCS control signals from the RDCU to multiple inverter or IGBT supply modules through reliable optical communication.
- Controls up to four parallel-connected modules from a single branching unit, simplifying system expansion.
- Maintains dependable optical data transmission while operating across a wide industrial temperature and humidity range.
ABB NPBU-42C 64011821D is used in drive systems that require coordinated communication between the control unit and multiple power modules. By distributing optical PPCS signals, the unit enables synchronized operation of parallel-connected inverter and IGBT supply modules. The branching architecture simplifies communication management while maintaining reliable signal integrity.
Applications using parallel-connected R8i IGBT supply units require a branching unit to distribute control commands correctly. ABB NPBU-42C 64011821D fulfills this requirement by transmitting signals from the RDCU to individual modules through the NDCU communication structure. One unit supports as many as four connected modules, providing an efficient solution for larger power configurations.
Industrial environments demand reliable communication equipment capable of continuous operation. ABB NPBU-42C 64011821D combines 24 V operation, PPCS optical communication, and broad environmental specifications to support dependable system performance. The unit is an effective choice wherever stable control signal distribution is essential for high-power ABB drive applications.
The NPBU-42C 64011821D ABB PPCS Branching Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
