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.
