Allen-Bradley 22C-D045A103 Variable Frequency Drive

Allen-Bradley PowerFlex 400 drive, model 22C-D045A103, is a 22 kW (30 HP) AC variable frequency drive designed for stand-alone motor control in fan and pump applications. Sized for 480V three-phase power, it provides adjustable output frequency to regulate motor speed and torque, making it suitable for HVAC, process, and other industrial loads that require precise speed control. As a member of the PF400 family, the 22C-D045A103 supports standard PowerFlex 400 control interfaces and incorporates built-in protections typical of the line to help safeguard motors during startup, operation, and fault conditions. This drive is intended for standalone installations where compact form factor and reliable performance are required, enabling straightforward integration with existing automation systems without the need for external controllers. Typical use cases include fans for ventilation and pumps in fluid handling or cooling systems, where consistent speed control improves energy efficiency and process stability.
