Overview
The Allen-Bradley 25A-D010N104 PowerFlex 523 is a compact, cost-effective variable frequency drive designed for industrial motor control. Operating from 380–480V AC 3-phase input and delivering 0–460V 3-phase output, this 4 kW (5 HP) drive provides reliable speed and torque control for standard induction motors. The Frame B enclosure in IP20 NEMA open-type configuration makes it suitable for control cabinets and non-hazardous environments.
Key Features
- Input Voltage Range: 380–480V AC, 3-phase; Output 0–460V 3-phase at 10.5 A
- Dual Control Methods: Volts/Hertz (V/Hz) and Sensorless Vector Control (SVC) for flexible motor tuning
- I/O Configuration: 5 sink/source inputs (1 dedicated stop, 4 programmable); 1 Form C relay output; analog I/O for 0–10V or 4–20 mA
