Allen-Bradley 1305-AA04A Variable Frequency Drive

The Allen-Bradley 1305-AA04A is a compact 0.75 kW (1 HP) adjustable-frequency drive (VFD) in the 1305 family, designed to regulate small AC motors from a 200–230 V supply. It accepts 200–230 V input (typically single-phase) and delivers up to 4.5 A of output current to a motor rated 0.75 kW / 1 HP, enabling precise speed control with 50/60 Hz operation. Variants exist within the same core rating, including 1305-AA04A-HAP, reflecting different enclosure or accessory configurations. Common applications include OEM equipment and light-industrial systems where smooth speed adjustments of small conveyors, pumps, or fans improve process control. The model is documented in Rockwell Automation literature for the 1305 series, with references to FRN firmware revisions and 50/60 Hz input, underscoring its place in the Allen-Bradley control ecosystem. Distributors and manuals consistently cite 200–230 V input, 4.5 A output, and a 0.75 kW (1 HP) motor rating for 1305-AA04A, confirming its standard specifications across listings.
