Overview
The Allen-Bradley 22A-D1P4N104 is a PowerFlex 4 Adjustable Frequency AC Drive that operates at 480VAC 3-Phase input and delivers 0.4 kW or 0.5 HP output power. The PowerFlex 4 is the smallest and most cost-effective member of the PowerFlex family, designed for flexibility, space savings, ease of use, and speed control of applications such as machine tools, fans, pumps and conveyors, and material handling systems.
Key Features
- 4 to 16 kilohertz carrier frequency with ±0.05% digital and 0.5% analog control accuracy
- 97.5% typical efficiency
- Volts/Hertz (V/Hz) control method for consistent speed by maintaining proportionality between frequency and voltage
- Sensorless Vector Control (SVC) support for torque control capabilities
- Panel mount enclosure with IP 20 NEMA Type Open rating
- Programmable output relay (form C) for automation integration
