ABB ACSM1 - Mains Choke Selection; Mains Choke Data

Mains choke selection
In common DC connections, the ACSM1 drive module(s) connected to AC
supply must be equipped with mains choke(s). Mains chokes are needed
• to get the maximum DC power ratings from the ACSM1 drive module(s)
• to reduce the AC input current (rms, peak) level
• to meet the requirements for harmonic distortion
• to balance the supply current in multiple AC input.
