The 3ADT218566S0131: 3300 A is the continuous output current for a 2Q converter — regenerative braking isn't built in, so if your DC motor needs to overhaul the load, you'll need an external braking chopper or a 4Q variant. The 400 VAC input is three-phase; the unit includes 3 analog inputs and 2 analog outputs for speed/torque reference and feedback loops. Sound level is 82 dB(A) — that's a continuous fan-cooled noise figure; ear protection zones are warranted within a couple of meters.
Installation environment
Auxiliary terminals are rated IP00 per IEC 60529 and IEC 60947-1 — that means no ingress protection at the connection points. The converter itself is intended for a clean, dry electrical room or cabinet with filtered ventilation. Operating humidity spans 5 to 95% RH, non-condensing. Frequency is 50 Hz line side.
This part carries an active product status — it's still in ABB's current catalog, not a last-time-buy or NRND line. That means factory lead times apply, and firmware/option module support is ongoing. No official successor has been issued because none is needed.
