The ABB S-123H 3BHB030479R0512 is a critical phase module (PHASE MODULE) designed specifically for the ACS6000 medium voltage AC drive series. As a standardized building block, this module is integral to the drive‘s power electronics, primarily utilized within the Active Rectifier Unit (ARU) or Inverter Unit (INU) cabinets to manage high-power conversion with precision and reliability.
Series Overview: ACS6000
The ACS6000 is a modular, high-power voltage source frequency converter platform engineered for demanding industrial applications. It is widely recognized for its use of IGCT (Integrated Gate Commutated Thyristor) technology, which ensures low losses, a fuse-less design, and high operational reliability. The series is designed to control induction, synchronous, and permanent magnet motors, offering a power range typically from 3.0 MW to 36.0 MW.
Function of the S-123H Phase Module
Within the ACS6000 topology, the phase module serves as the core switching component. It houses the power semiconductors (IGCTs), diodes, and clamp capacitors required for the 3-level voltage source inverter topology.
Role: It performs the actual conversion between DC and AC voltage. In the ARU, it rectifies incoming AC power to the DC link; in the INU, it inverts the DC link voltage back to a variable-frequency and variable-voltage AC output to control the motor.
Specifications: This specific module (S-123H) is often associated with the 12 MVA power class within the ACS6000 system, featuring a robust design for high-voltage isolation and efficient thermal management (typically water-cooled).
Application Scope of the Series
The ACS6000 series, and by extension its phase modules, is deployed in heavy industries requiring high dynamic performance and energy efficiency. Key application areas include:
Metals & Mining: Rolling mills, mine hoists, and grinding mills.
Marine: Electric propulsion systems (Azipod®) and thrusters.
