Allen-Bradley 22B-D4P0N104 Variable Frequency Drive

The Allen-Bradley 22B-D4P0N104 PowerFlex 40 AC Drive is a compact, three-phase variable frequency drive in Rockwell Automation's PowerFlex family, engineered to deliver reliable speed control for moderate-size 480 VAC motor loads while fitting neatly into standard industrial control panels. Designed for 380–480 VAC three-phase input, it provides up to 1.5 kW (2 HP) of output with a 4 A rating, enabling smooth ramping, precise frequency control, and basic motor protection in 3-phase motor applications. The drive comes in a Panel Mount IP20 enclosure (Frame Size B) and is offered as an open NEMA/UL type unit, combining robust construction with straightforward wiring; user interaction is via an LED display and a digital keypad, while RS-485 supports simple network integration. A note of caution: this model is documented as not including a CE-compliant EMI filter, so if EMI suppression is required by your installation, it should be added externally to meet applicable standards.
