The ABB 3ADT218519S0141 is a DCS880-S01-0270-04 2-quadrant DC converter rated for 400 VAC input and 270 A output, in frame size H2. It operates at 50 Hz and carries three analog inputs and two analog outputs. The auxiliary terminals are IP00 per IEC 60529 and IEC 60947-1; the unit measures 55 dB(A) sound pressure and tolerates 5 to 95 % RH ambient humidity.
The 270 A output is the continuous rated current for a 2Q DC drive feeding a shunt or permanent-magnet motor on a 400 VAC three-phase supply. Frame H2 defines the mechanical footprint and bus-bar layout; the IP00 auxiliary terminals mean those connections are unprotected — panel builders must house the converter in an enclosure rated for the environment. The 55 dB(A) sound level is typical for a drive of this power class at full load; it is not a selection constraint unless the cabinet is in a noise-sensitive area.
