ABB 3BHB007030R0103 UFC760 BE103

The 3BHB007030R0103 UFC760 BE103 is a high-speed drive control processor board for ABB ACS6000 medium voltage IGCT drive platform. This 3BHB007030R0103 UFC760 BE103 executes core closed-loop motor control, pulse generation and fault protection logic, communicating with other UFC760 series boards via the internal drive backplane bus. The 3BHB007030R0103 UFC760 BE103 handles current regulation, speed loop calculation and IGCT firing pulse sequencing for four-quadrant medium voltage converters.

This 3BHB007030R0103 UFC760 BE103 is conformal coated to resist dust and humidity inside high voltage converter cabinets. Front LED indicators display power, running and fault status for rapid on-site diagnosis. It collects feedback from current sensors, voltage sensors and temperature monitoring circuits, and triggers protective shutdown when overcurrent, overvoltage or overtemperature faults are detected. The suffix BE103 defines the specific hardware revision and firmware configuration of this processor variant.

The 3BHB007030R0103 UFC760 BE103 is widely used for medium voltage drives driving compressors, fans, pumps and rolling mill main motors in power plants, mining and metallurgical industries. The ACS6000 drive platform including this 3BHB007030R0103 UFC760 BE103 is discontinued by ABB. Most available units are tested surplus spare parts for overhaul and emergency replacement of existing ACS6000 control racks.
