Allen-Bradley 22DD1P4N104 Variable Frequency Drive

The Allen-Bradley PowerFlex 40P drive, catalog number 22D-D1P4N104 (also listed as 22DD1P4N104), is a 480V three‑phase variable frequency drive designed for small motor control up to 0.5 HP (about 0.37 kW). It is a panel‑mount device with an IP20 enclosure (NEMA Type Open) and uses PowerFlex 40P frame size B, making it a compact option for compact, low‑power applications. The drive draws approximately 1.4 A on a 480V three‑phase supply and is configured as a CE‑filterless (no CE‑compliant filter) variant in many listings. The unit features a simple display with reset‑only access and provides standard PowerFlex 40P functionality suitable for basic speed control, ramping, and motor protection in light‑duty environments. Common applications include small three‑phase motors in systems such as fans, pumps, conveyors, or other auxiliary equipment where precise speed control at 480V is required. This model is part of the PowerFlex 40P family and is widely cataloged as a 22D‑D1P4N104 variant for 480V operation.
