The ABB 3ADT218518S0141 is a DCS880-S01-0090-04 DC converter — a 2-quadrant unit rated for 400 VAC input and 90 A output, built in frame size H1. It carries three analog inputs and two analog outputs, and runs at 50 Hz. The sound level sits at 55 dB(A).
The 90 A output rating on a 2Q converter means it handles motoring and regenerative braking in one direction — no reversing. Frame H1 keeps the physical footprint manageable for a 90 A DC drive. The 55 dB(A) noise level is worth noting if the cabinet sits near a worksurface; it is audible but not loud enough to require an enclosure for sound alone.
