The Allen-Bradley 20F14NC104AA0NNNNN is a PowerFlex 753 AC drive for the 400 V AC / 540 V DC class in frame 5, built as an IP20, NEMA/UL Type Open wall-mount chassis with DC input with precharge (common bus). Rockwell rates it at 104 A and 55 kW for normal duty and 85 A and 45 kW for heavy duty. This version has filtering with the common mode capacitor jumper removed (Rockwell now lists code A as no longer available) and the internal dynamic braking transistor installed. The PowerFlex 753 is Rockwell's general-purpose 750-Series drive for applications up to 400 Hp and 270 kW, with built-in I/O, slot-based option cards, DeviceLogix embedded control and Ethernet available through a communication module.
