The ABB 3ADT218520S0242 is a DCS880-S02-0520-05 DC converter — a 4-quadrant regenerative unit rated at 525 VAC input and 520 A output, in frame size H3. It carries three analog inputs and two analog outputs, with a declared sound level of 60 dB(A).
Frame size H3 defines the mechanical footprint and bus-bar layout — critical for panel cut-out and cable entry planning. The 525 VAC input is a nominal three-phase AC supply; the 520 A output is the continuous DC rating in the 4Q regenerative mode. Three analog inputs and two analog outputs cover typical speed/torque reference and feedback loops without an expansion module. The 60 dB(A) sound level is the fan noise at full load — relevant if the drive sits near a quiet zone. Auxiliary terminals carry an IP00 rating per IEC 60529, meaning they are not touch-protected; panel builders must account for this in the enclosure design.
Environmental range
Rated for 5 to 95% operating humidity (non-condensing) and 50 Hz line frequency. The IP00 auxiliary terminals require the host panel to provide the environmental seal.
