Form factor and what it slots into
The 6SL3220-1YD20-0UB0: It is a mature product on the manufacturer's books, so the panel cutout, footprint and connector geometry are stable across long production runs and field replacements fit into existing cabinets without re-engineering.
Line-side electrical envelope, 380-440 V three-phase
Line input is 3 AC across 380... 440 V with a +10 % / -20 % tolerance, and the input stage accepts 47... 63 Hz — covering 50 Hz industrial mains and 60 Hz North-American grids without a tap change. The low-overload rated current of 2.10 A defines the practical motor size the converter will drive continuously on the LO duty profile; any sizing calculation has to use this number as the continuous ceiling, not the heavier-duty figure from a sibling rating.
Procurement posture for a mature line
Estimated lead time is listed at 1-10 working days; quantities and pricing are confirmed against an RFQ rather than carried as a fixed shelf price, which is the standard posture for a mature converter module of this class.
