Allen-Bradley 20F1AND248AA0NNNNN PowerFlex 753 AC Drive 248A 200HP

Product Overview

This unit is a 753 AC Drive from Allen-Bradley, part of the PowerFlex 753 product line. It features embedded I/O and is air-cooled. The drive accepts AC input with precharge and has no DC terminals. It is an open-type design, rated IP20 / IP00, and comes in Frame 6. The unit includes a filtered configuration with an EMI filter (jumper out) and a DB transistor for dynamic braking. It supports analog and digital I/O and offers three expansion slots for customization. Note: this unit does not include a local HIM.

Technical Specifications Breakdown

Key parameters for the 20F1AND248AA0NNNNN are listed below for quick reference:

Industry Applications

In conveyor systems, the 248A output and 200HP ND rating ensure smooth material handling under variable loads. For pump and fan control, the built-in overload protection (110% for one minute, 150% for three seconds) safeguards against jams or surges. The IP20 enclosure suits indoor installations in manufacturing plants, while the air-cooled design maintains performance in ambient temperatures up to 50°C.

Installation & Setup Guidance

Mount the drive in a clean, dry location with adequate airflow. Ensure the input voltage matches the 480V AC, 3-phase requirement. The AC input with precharge simplifies integration with existing systems. Use the three expansion slots for optional communication or I/O modules as needed. Since the unit has no local HIM, configure parameters via a connected HIM or software. Verify that the DB transistor braking is correctly wired if dynamic braking is required.

Maintenance & Reliability

Inspect cooling fans and air filters regularly to prevent overheating. Monitor ambient temperature to stay within the 0–50°C range. Check for loose connections and signs of dust accumulation. The EMI filter (jumper out) helps reduce interference; ensure it remains properly configured. For safety-rated equipment, perform general inspections without disassembly. Contact AutoDCSTech for lifecycle status before ordering.

Compatibility & Integration

The drive supports analog and digital I/O for flexible control. With three expansion slots, you can add modules for network protocols (e.g., EtherNet/IP, DeviceNet) as needed. The DB transistor allows integration with external braking resistors. The unit is designed for 480V AC systems and can also accept 650V DC input for DC bus sharing applications.

Selection Guide & Purchasing Advice

When selecting a drive, match the output current and horsepower to your motor. The 20F1AND248AA0NNNNN suits 200HP normal duty or 150HP heavy duty loads. Verify the enclosure type (IP20/IP00) fits your environment. For availability and lifecycle information, consult AutoDCSTech, your trusted industrial automation parts supplier.

Troubleshooting & Common Issues

If the drive fails to start, check the input power supply for correct voltage and phase. Overload trips may indicate mechanical binding or incorrect parameter settings. Verify that the ambient temperature is within the 0–50°C range. For communication issues, ensure expansion modules are properly seated. Always refer to the official PowerFlex 753 manual for detailed diagnostics.
