When production downtime and energy costs escalate, the Allen-Bradley 25B-A011N104 PowerFlex 525 adjustable frequency drive delivers a reliable, cost-efficient solution. This industrial automation module combines advanced motor control with embedded connectivity to reduce installation and operational expenses.
Product Overview
The Allen-Bradley 25B-A011N104 is a PowerFlex 525 series AC drive from Rockwell Automation. It operates on a 200–240 VAC single-phase input and provides a 0–230 VAC three-phase output. Rated at 11 amperes output current, this drive delivers 3 horsepower (2.2 kW) for light to medium-duty applications. The 25B-A011N104 features a Frame B size, IP20 NEMA open enclosure, and a standard interface module without EMC filtering.

The 25B-A011N104 supports multiple control modes including volts per hertz, sensorless vector, closed-loop velocity vector, and positioning. Its LCD module scrolls text for easy setup. An embedded Ethernet port integrates seamlessly into Logix environments, while the integral RS485/DSI port enables multi-drop networking. The detachable control and power modules allow simultaneous installation and configuration, saving labor time.
Industry Applications
The 25B-A011N104 excels in open-loop and closed-loop speed regulation tasks. Typical applications include conveyors, pumps, fans, and simple positioning systems. For instance, in a packaging line, the drive’s closed-loop velocity vector control minimizes speed variation, reducing product waste. The integrated Ethernet eliminates separate communication hardware, lowering total system cost—a key ROI advantage.
Installation & Setup Guidance
Mount the 25B-A011N104 on a DIN rail. Maintain a minimum clearance of 1.96 inches (50 mm) at the top and bottom for airflow. The ambient operating temperature range is -20 to 50°C. The relay precharge logic prevents inrush currents during startup. Connect single-phase input to L1 and L2 terminals; three-phase motor output connects to T1, T2, T3. Use the detachable control module for wiring ease. No EMC filter is present, so install external filtering if required by the environment.
Selection Guide & Purchasing Advice
Before ordering the 25B-A011N104, verify your input supply matches the 200–240 VAC single-phase rating and that the motor’s full-load current does not exceed 11 amps. Confirm the enclosure rating (IP20) suits your environment. For applications needing EMC compliance, consider an external filter.
