Allen Bradley 22C-D208A103 PowerFlex 400 AC Drive

Applications

The Allen-Bradley 22C-D208A103 PowerFlex 400 AC Drive is a high-power variable frequency drive designed for large industrial fan and pump systems. With a rated output of 110 kW (150 HP) and a 208 A output current, it provides adjustable speed control for three-phase AC motors in demanding variable-torque applications.

Typical applications include:

• Large HVAC air handling and ventilation systems

• Industrial exhaust and circulation fans

• Cooling tower and condenser water pumps

• Water supply and wastewater treatment facilities

• Industrial process cooling and fluid circulation

• Large-scale building utility systems

By adjusting motor speed to match actual system demand, the drive can support stable process operation and help reduce unnecessary energy consumption in suitable variable-torque applications.

Advantages and Key Features

• High-power motor control: Provides a 110 kW (150 HP) rating and 208 A output current for large motor-driven equipment.

• Local keypad operation: Provides an operator interface for monitoring drive status and adjusting operating parameters.

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

• High-power frame design: Supports integration into larger fan and pump control installations.

Technical FAQs

1. What is the primary function of the 22C-D208A103?

It is an adjustable frequency AC drive used to regulate the speed of three-phase AC motors, particularly in large fan and pump applications.

2. What is the rated power of this model?

The 22C-D208A103 is rated at 110 kW (150 HP) for its specified 480V three-phase configuration.

3. What is its rated output current?

Its rated output current is 208 A. The connected motor's nameplate current and actual load conditions should be checked during drive selection.

4. What input power supply does it use?

This catalog model is designed for a 480V AC three-phase power system. Confirm the permitted input voltage range on the product nameplate and applicable technical documentation.

5. Does the drive support RS-485 communication?

Yes. The PowerFlex 400 family supports RS-485 serial communication for connection to compatible automation and monitoring systems.

6. Can it be integrated with a PLC?

Yes. It can be incorporated into a PLC-based control system through supported control connections and serial communication. The wiring, command source, and communication parameters must be configured correctly.

7. Does the 22C-D208A103 include a braking IGBT?

This catalog configuration should be checked against its nameplate and technical documentation before a braking arrangement is specified. Do not assume that a braking IGBT is included.

8. What is the purpose of the local keypad?

The keypad provides a local interface for drive operation, status monitoring, and parameter configuration, subject to the configured command and reference sources.

9. What should be checked before commissioning?

Verify the incoming supply, motor nameplate data, grounding, power and control wiring, protective devices, ventilation, and drive parameters. Confirm that the drive is correctly rated for the motor and load.

10. What should be checked if the drive trips during operation?

Review the displayed fault code and operating history. Check the supply voltage, motor current, load condition, wiring, cooling and ventilation, and configured protection parameters. Correct the underlying issue before resetting the drive.
