For a compact inverter drive that provides powerful and precise motor speed control, look no further than the PowerFlex 4 AC drives by Allen Bradley. These PowerFlex devices have a space-saving design and can be DIN rail or panel mounted. It is the smallest member of the PowerFlex Variable Frequency Drive family and is designed for optimal flexibility and ease-of-use. It offers an economical alternative for speed control of applications such as pumps, conveyors, fans, machine tools, and material handling systems.

PowerFlex 4 devices are available in power ratings from 0.2 to 1.5kW (single phase) and 0.37 to 3.7 kW (3 phase) in voltage classes of 230 and 400 volts. They offer V/Hz control, slip compensation, RS-485 communication, and Auto Restart and Flying Start functions. Integral dynamic brake resistor is available on ratings 0.75kW and above.
