Provide Optimized Simplicity

Providing users with powerful motor speed control in a compact, space savings design, the Allen-Bradley PowerFlex 4 Class AC drives are the smallest and most cost effective members of the PowerFlex family of drives. The PowerFlex 4 Class of drives consists of two products, the PowerFlex? 4 and PowerFlex'" 40. Ideal for machine level speed control, these products provide the application versatility to meet the demands of global OEMs and end users who require flexibility, space savings and ease of use. The PowerFlex 4 and PowerFlex 40 AC drives have commonality in three key areas.

Flexible Packaging and Mounting Options

• Installation can be a virtual snap using the DIN rail mounting feature on ratings through 4 kW (5 hp). Panel mounting is also available providing added flexibility.
• Zero Stacking™ is allowable for ambient temperatures up to 40?C, saving valuable panel space. 50?C ambient temperatures are permitted with minimal spacing between drives.
  

Easy to Start up and Operate

• Integral keypad features a 4 digit display and 10 additional LED indicators providing intuitive control.
• The keypad and control keys and local potentiometer are active out of the box, simplifying start up.
• The 10 most commonly programmed parameters are grouped together for fast and easy start up.
