Description
Product Name : 160-AA04NPS1 Allen Braley Input module
Product details:
The Allen-Bradley 160-AA04NPS1 is a compact, high-performance AC variable frequency drive (VFD) from the Bulletin 160 SSC (Sensorless Vector Control) series. Although this series has been largely superseded by the PowerFlex family, it remains a staple in many legacy industrial systems due to its reliability and small footprint.
Product Description
The 160-AA04NPS1 is an adjustable frequency AC drive designed to control the speed of three-phase induction motors. It utilizes Sensorless Vector Control, which provides high torque even at low speeds without the need for an encoder.
The “N” in the model number indicates it is an Open Enclosure (IP20) type, and the “P” signifies that it comes with a Program Keypad Module for easy parameter adjustment and monitoring.
Technical Parameters
| Feature | Specification |
| Input Voltage | 200–240V AC (3-Phase) |
| Output Current | 4.5 Amperes |
| Power Rating | 0.75 kW / 1.0 HP |
| Input Frequency | 50/60 Hz |
| Output Frequency | 0–240 Hz |
| Enclosure Type | IP20 (Open Style) |
| Control Method | Sensorless Vector Control or Volts/Hertz |
| Model Series | Bulletin 160 SSC |
Key Advantages
- Compact Design: One of the smallest drives in its class, making it ideal for crowded control panels.
- Sensorless Vector Performance: Delivers excellent speed regulation and high starting torque for demanding loads.
- DIN Rail Mounting: Supports quick and easy installation onto standard 35mm DIN rails.
- Versatile Programming: The integrated keypad allows for rapid setup of acceleration/deceleration times, current limits, and preset speeds.
- Reliability: Built with industrial-grade protection against overvoltage, undervoltage, and short circuits.
Important Considerations (Precautions)
- Cooling & Clearance: Ensure adequate airflow around the unit. Since it is an IP20 open-style drive, it must be mounted in a clean, dry environment within a protective enclosure.
- Input Power: Verify that the supply voltage matches the 200-240V range. Applying 480V will result in immediate hardware failure.
- Grounding: Proper grounding is essential to reduce electromagnetic interference (EMI) and ensure operator safety.
- Legacy Status: As this is a discontinued/legacy series, sourcing replacement parts may require contacting specialized industrial surplus suppliers. Consider upgrading to the PowerFlex 525 series for long-term future-proofing.
Common Applications
The 160-AA04NPS1 is widely used in low-power industrial automation tasks, including:
- Conveyor Systems: For smooth start/stop transitions and variable speed sorting.
- Packaging Machinery: Precise control of wrapping or labeling speeds.
- Fans and Pumps: Energy saving through flow control rather than mechanical throttling.
- Material Handling: Small lifts, turntables, and feeders.
- Machine Tools: Controlling spindles or auxiliary feed motors.
