DC converter for 525 VAC lines — 270 A, Frame H2
The 3ADT218519S0142: The 270 A rating is the continuous output current for a 2Q (regenerative braking not included) DC drive — sized for a motor load pulling that current on a 525 V bus. Frame H2 means the mechanical package and busbar layout match the DCS880 family's H2 footprint; panel cutouts and mounting holes follow that standard.
I/O and environmental limits
Three analog inputs and two analog outputs are available on the control board — enough for a speed reference, a tacho feedback, and a current or torque limit signal, with one spare output for a meter or drive-health relay. The auxiliary terminals carry an IP00 rating per IEC 60529 and IEC 60947-1 — meaning no ingress protection on the control wiring terminations themselves. In a panel environment that is normal; the enclosure door provides the IP rating for the whole assembly. Operating humidity range is 5 to 95% RH, non-condensing. Acoustic noise measures 55 dB(A) — roughly the level of a quiet office printer, not a concern for most machine rooms.
