Description
1. Product Title
ABB 802A001B-1 – ACS800 Inverter Internal Interface Control Board
2. Product Overview
The 802A001B-1 is a genuine internal auxiliary printed circuit board specially designed for ABB ACS800 series multidrive and single drive variable frequency systems. It acts as an intermediate signal transfer and secondary logic coordination unit inside the inverter cabinet, responsible for distributing control power, collecting temperature feedback signals from power modules, transmitting fault alarm codes, and realizing electrical interlock between the main CPU board and peripheral functional subassemblies. Equipped with built-in surge suppression components and EMC filtering circuits, 802A001B-1 effectively mitigates high-frequency electromagnetic interference generated by IGBT power units and rectifier bridges, stabilizes the internal signal loop of the drive, and ensures accurate overheat protection, phase loss detection and fault self-diagnosis during continuous heavy-load operation. It serves as an essential spare part for repairing aging ACS800 inverters, eliminating sporadic fault trips and restoring full rated performance of large variable-speed driving equipment.
