Allen Bradley 22C-D170A103 PowerFlex 400 AC Drive

Applications

The Allen-Bradley 22C-D170A103 PowerFlex 400 AC Drive is a high-power variable frequency drive designed for commercial and industrial fan and pump systems. With a rated output of 90 kW (125 HP) and 170 A, it provides adjustable speed control for large three-phase motors in demanding variable-torque applications.

Typical applications include:

• Large industrial ventilation and exhaust fans

• HVAC air handling and circulation systems

• Cooling tower and condenser water pumps

• Water supply and wastewater treatment facilities

• Industrial process cooling and fluid circulation

• Building utility and environmental control systems

By adjusting motor speed to match actual system demand, the drive can support more precise flow and pressure control while helping reduce unnecessary energy consumption.

Technical FAQs

1. What is the primary function of the 22C-D170A103?

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

2. What is the rated power of this drive?

The 22C-D170A103 is rated at 90 kW (125 HP) for its 480V AC three-phase configuration.

3. What is its rated output current?

Its rated output current is 170 A. The motor's nameplate current and actual operating conditions should be checked when selecting the drive.

4. What input voltage does the 22C-D170A103 support?

It is a 480V AC three-phase model. The published input voltage range is 340–528V AC. The supply must remain within the permitted operating range.

5. Does this model support RS-485 communication?

Yes. It includes an RS-485 communication interface for connection to compatible control and monitoring systems.

6. Can the drive be integrated into a PLC-based system?

Yes. It can be integrated with compatible PLC systems through supported control connections and RS-485 communication. Correct wiring and communication parameter configuration are necessary.

7. Does the 22C-D170A103 include a braking IGBT?

No. This catalog configuration does not include a built-in braking IGBT. If the application requires dynamic braking, the braking method and compatible external components must be evaluated separately.

8. What operator interface does this model have?

It features a fixed keypad with an LED display, allowing operators to monitor drive status, issue local commands, and configure parameters.

9. What should be checked before commissioning?

Verify the input supply, motor nameplate information, grounding, power and control wiring, protective devices, and configured operating parameters. Confirm that the drive rating is suitable for the motor and load.

10. What should be inspected if the connected motor fails to start?

Check the incoming power supply, active fault indications, run command source, enable and interlock signals, motor wiring, and parameter settings. Identify and correct the fault condition before resetting and restarting the drive.
