Allen-Bradley 1333-DAN AC Variable Frequency Drive

Allen-Bradley 1333-DAN AC Variable Frequency Drive is a Bulletin 1333 Series D adjustable-frequency drive that accepts 3‑phase 380 V input and delivers 7.5 HP (5.5 kW) of output to control a standard three‑phase motor. This model is designed for industrial applications where motor speed is varied by adjusting the output frequency and voltage, enabling precise control of equipment such as conveyors, fans, pumps, and other automated machinery. The 1333 family encompasses models configured for 380/415/460 V three‑phase input, with the 1333‑DAN variant specifically targeting 380 V installations to support mid‑range horsepower needs within Rockwell Automation’s legacy drive lineup. As part of Allen‑Bradley’s established motor-control portfolio, it integrates with common Rockwell control schemes and is suited for upgrading older equipment or implementing reliable speed control in automation projects.
