Allen Bradley 22C-D105A103 PowerFlex 400 AC Drive

Applications

The Allen-Bradley 22C-D105A103 PowerFlex 400 AC Drive is designed for variable-speed control of fan and pump systems in commercial and industrial facilities. It can help regulate motor speed according to process demand, supporting more efficient operation in applications where flow and pressure requirements change over time.

Typical applications include:

• HVAC supply and return fans

• Cooling tower and condenser water pumps

• Industrial ventilation systems

• Water supply and wastewater treatment

• Process cooling and circulation pumps

• Building automation and utility systems

Its fan-and-pump-oriented design makes it suitable for systems that require reliable motor speed regulation and integration into larger automation installations.

Advantages and Key Features

• High-power motor control: Rated at 55 kW (75 HP) with a 105 A output current for larger fan and pump installations.

• Fan and pump optimization: Designed for variable-torque applications where motor speed can be adjusted to match system demand.

• Three-phase power input: Operates on a 480V AC, three-phase supply.

• Integrated RS-485 communication: Supports serial communication for connection with compatible control and monitoring systems.

• Built-in operator interface: The fixed keypad provides a local interface for drive operation and parameter configuration.

• Industrial enclosure: The IP30, NEMA/UL Type 1 enclosure is intended for installation in a suitable protected electrical environment.

• Application-oriented functions: PowerFlex 400 drives include features intended for fan and pump systems, helping simplify motor control and system integration.

Technical FAQs

1. What type of applications is the 22C-D105A103 designed for?

It is designed primarily for variable-torque applications, including industrial fans, ventilation equipment, cooling systems, and water pumps.

2. What is the rated motor power of this drive?

The drive is rated at 55 kW (75 HP) for its 480V AC, three-phase configuration.

3. What is its rated output current?

The catalog rating is 105 A. The connected motor's nameplate current and application duty should be checked before selecting the drive.

4. What input power supply does it require?

It is a 480V AC, three-phase model. The published technical data specifies an input voltage range of 340–528V AC. The actual supply must remain within the applicable operating limits.

5. Does the 22C-D105A103 support RS-485 communication?

Yes. This catalog configuration includes an RS-485 communication interface for compatible serial communication and control arrangements.

6. Can the drive be controlled by a PLC?

Yes. It can be incorporated into a PLC-based system using its supported control I/O and RS-485 communication. The control method and communication parameters must be configured for the connected PLC or interface.

7. Does this model have a built-in braking IGBT?

No. The 22C-D105A103 version is specified without a braking IGBT. If the application requires dynamic braking, confirm the appropriate external braking solution and drive compatibility.

8. Does it include a local operator keypad?

Yes. This version has a fixed keypad for local operation, monitoring, and parameter setup.

9. What should be checked before commissioning?

Verify the supply voltage, motor nameplate data, wiring, grounding, protective devices, control connections, and drive parameters. Confirm that the motor and load are suitable for the drive's current and power ratings before starting the system.

10. What should be checked if the motor does not run?

Check the incoming power supply, drive status and fault display, run command source, enable and interlock signals, motor wiring, and configured start/stop parameters. Correct the cause of any active fault before resetting and restarting the drive.
