Overview
The Allen-Bradley 25B-D6P0N104 is a PowerFlex 525 series general-purpose AC drive engineered for flexible motor speed and torque control. Rated at 2.2 kW (3 HP) with a 6A continuous output, this drive handles 380–480V three-phase AC input at 50–60 Hz, making it suitable for a wide range of industrial automation and process control applications. Built-in safety features, networked communication, and multiple motor control modes deliver cost-effective performance for fans, pumps, conveyors, and machine drives.
Key Features
- Embedded EtherNet/IP: Seamless integration with Logix controllers and industrial networks for real-time monitoring and control.
- Safe Torque-Off (STO): Standard safety feature compliant with ISO 13849-1 (SIL 2/PLd) that removes rotational power without powering down the drive.
- Multiple Motor Control Methods: Supports Sinusoidal PWM, Volts/Hertz, Sensorless Vector Control, Closed-Loop Velocity Vector Control, and Economizer SVC.
- Integral IGBT Braking System: Efficient deceleration and overload protection for demanding applications.
- Removable Control Module: Allows offline programming via USB and simultaneous installation of power module for faster commissioning.
- Compact Frame A Design: Panel or DIN rail mounting for flexible cabinet integration.
Technical Specifications
Input power range spans 380–480V AC, three-phase, 50–60 Hz operation. The drive outputs 6.0A continuous (9A for 60 seconds) at frequencies from 0–500 Hz into a connected three-phase induction motor. Internal protection includes integral EMC filtering, fast-acting current limiting, and automated bus voltage management. The IP20 NEMA Type Open enclosure with Frame A Form Factor measures approximately 22.7 × 23.0 × 24.0 cm and weighs 1.4 kg. Fixed terminal block connections simplify wiring, and a backlit LCD display provides status information and fault diagnostics. Operating altitude rating is 1000 m (3300 ft) without derating, or up to 4000 m (13,200 ft) with derating.
Typical Applications
The 25B-D6P0N104 excels in applications requiring variable speed control with flexible motor feedback options:
- Pump and Fan Control: Sensorless vector control delivers excellent speed regulation and torque characteristics at part load.
- Conveyor Systems: Closed-loop velocity feedback for consistent line speed without load variation.
- Machine Tool Drives: Integrated braking and multiple control modes support precise motion profiles.
- HVAC and Refrigeration: Energy-saving Economizer SVC mode reduces power consumption during light-load operation.
- Material Handling: Configurable safety functions and encoder feedback for position-critical applications.
