Description
Product Overview
The ABB S-123H (3BHB030479R0512) phase module is a dedicated control board for the ABB ACS6000 medium voltage inverter series. It collects three-phase grid voltage signals, detects phase sequence, captures zero-crossing points, monitors overvoltage and undervoltage faults, and outputs stable synchronous reference signals for IGCT power units. This synchronization function is critical for the reliable triggering of high-power power units. It is widely deployed in large power transmission scenarios such as power plant fans & water pumps, metallurgical rolling mills, and mine hoists. The ACS6000 platform is end-of-life by ABB, and this module is a scarce after-sales maintenance spare part.
