3ADT218567S0246 ABB DCS880-S02-4000-10R DC Converter, 4000 A

The 3ADT218567S0246: The 82 dB(A) sound level is the acoustic noise at rated load, driven by the cooling fans and magnetics. For a drive of this power class, that figure is typical — plan for hearing protection if the cabinet is on the plant floor, and verify that adjacent sensitive equipment (e.g., microphones, acoustic sensors) can tolerate the level. Three analog inputs and two analog outputs are available for speed/torque reference, feedback, and process signals. The IP00 rating on the auxiliary terminals means those connections are not protected against solid objects or moisture — they must be housed inside an enclosure that provides the overall system IP rating. Rated for 50 Hz line frequency and 5...95% non-condensing humidity, the converter is suited for standard industrial environments. The wide humidity range covers most indoor installations, including unheated warehouses.
