Allen-Bradley PowerFlex 400 22C-D030N103 AC Drive 30 Amp

Allen-Bradley 22C-D030N103 PowerFlex 400 AC Drive 15kW 20HP 480V

Product Description

The 22C-D030N103 (22C-D030N103) is a specialized Variable Frequency Drive (VFD) from the Allen-Bradley PowerFlex 400 series, specifically engineered for commercial and industrial fan and pump applications. This Frame C drive is optimized for high-demand HVAC and fluid management systems, providing a robust 30 Amp output current to handle 3-phase induction motors rated up to 15 kW (20 HP) at 480V AC.

Designed for seamless integration into building automation and process control environments, the 22C-D030N103 (22C-D030N103) includes embedded RS-485 communications and a built-in PID controller. These features allow for precise pressure and flow regulation without the need for additional external controllers. Its IP20 / NEMA Type Open enclosure is designed for clean-environment cabinet mounting, ensuring efficient thermal management through forced-air cooling.

Core Performance Features

• HVAC Specific Firmware: Includes specialized functions such as "Purge" (Fireman’s override), "Sleep Mode" for energy savings during low demand, and "Skip Frequencies" to avoid mechanical resonance.

• Integrated PID Control: Enables the drive to maintain a constant pressure or flow setpoint by adjusting motor speed based on feedback from a 4-20mA sensor.

• Flying Start: Allows the drive to smoothly pick up a motor that is already spinning (e.g., a fan rotating due to back-draft) without tripping on overcurrent.

• Connectivity Options: Built-in RS-485 allows native connection to popular building automation protocols including Johnson Controls Metasys N2 and Siemens P1-FLN.

• Auxiliary Motor Control: Supports the "Auxiliary Motor" feature to control up to two additional line-started motors to assist during peak demand periods.
