The ABB 3ADT218587S0122 is a DCS880-S01-1200-05 DC converter — a 2-quadrant unit rated for 1200 A at 525 VAC input, in Frame H6. That puts it in the heavy end of the DCS880 line, sized for large DC motor drives or regenerative loads where you need controlled DC output from a three-phase AC supply.
Three analog inputs and two analog outputs are available for speed reference, current feedback, or process signals — enough for a basic drive control loop without an external I/O block. Sound level is listed at 73 dB(A) — that's the fan noise at full load. In a control room or quiet production area, factor that into the ambient noise budget.
