Overview
The Allen-Bradley 160-AA04NSF1P1 is a variable speed drive from the 160 Smart Speed Controller (SSC) series, engineered for precise AC motor speed regulation in industrial automation. This analog signal follower drive delivers proportional speed control across a wide power range and operates reliably in IP20 open enclosure environments, making it suitable for retrofit installations and space-constrained panel applications.
Key Features
- Analog Signal Follower Control: Accepts potentiometer, 4–20 mA, or ±10 VDC analog inputs for smooth proportional speed adjustment.
- Program Keypad Module: Onboard local control panel for setup, diagnostics, and parameter access without external controllers.
- Compact Design: 152 mm height, 80 mm length, and 165.4 mm depth allows installation in tight panel spaces or on DIN rail.
- Feed-Through Power Terminals: 6-pole terminals simplify wiring for constant-speed retrofits with minimal configuration.
- Protected DC Bus: Test points and built-in protection circuits (overvoltage, undervoltage, over-temperature) enhance reliability.
Technical Specifications
- Input Voltage Range: 180 V to 356 V AC (nominal 200–240 V)
- Input Current: 2.7 kVA power requirement
- Output Rating: 0.75 kW; output current 4.5 Amperes
- Motor Power: 1 HP / 0.75 kW maximum
- Phase Configuration: 3 Phase Input and 200–240V Voltage Rating
- Enclosure: IP20 (open style)
- Braking: Dynamic braking torque of 100% without external resistor; 200% with external braking resistor
- Power Dissipation: 35 Watts (open style enclosure)
- Operating Temperature: 0 to 50 degrees Celsius
- Protection: Under-voltage protection at 210 V DC, over-temperature protection
Typical Applications
- Constant-speed motor retrofits in existing machinery and conveyor systems
- Proportional speed control for pumps, fans, and blowers requiring soft starting
- Industrial automation where field control via analog 4–20 mA loop or potentiometer is required
- OEM equipment requiring compact, integrated motor control without PLC integration
- Maintenance and repair of legacy Allen-Bradley automated systems
Compatibility & Replacements
The Allen Bradley 160-AA04NSF1P1 has been discontinued by the manufacturer, but remains widely available in the used and refurbished surplus market. Modern replacements include the PowerFlex 4M (compact general-purpose drives) or PowerFlex 525 (for networked control). For drop-in compatibility, verify input voltage, motor horsepower, and control signal type (analog vs. digital). This unit features 3 Phase Input and IP20 Open Enclosure with Analog Signal Follower Model Type, which should match legacy systems expecting those specifications.
