Continuous-current ladder
The catalog steps deliver 22 A, 27 A and 34 A continuously.
Allen-Bradley 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 PowerFlex 70 AC Drives
480 VAC · Frame D · Three rating steps
Product Description
The Allen-Bradley 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 group places three 480 VAC PowerFlex 70 output levels in the same Frame D format. Continuous current rises through 22 A, 27 A and 34 A, corresponding to 15 HP, 20 HP and 25 HP normal-duty motor ratings.
Short-duration capacity differentiates 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 further: their one-minute outputs are 24.2 A, 33 A and 40.5 A, and their three-second outputs are 33 A, 44 A and 54 A. The common enclosure, filter, brake IGBT and I/O option remain unchanged while the power stage changes.
Each 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 configuration uses panel mounting, conformal coating and second-environment filtering. The standard-control terminals receive analog references and digital commands, while the blank HIM and no-communication-module options keep those interfaces outside the supplied base drive.

Performance Characteristics: D-Frame Rating Ladder
20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 share the D-frame package but provide three different continuous and overload envelopes.
02
One-minute capacity
The middle and upper models increase more sharply to 33 A and 40.5 A, while the 22 A model reaches 24.2 A.
03
Three-second peak
Short events are covered by 33 A, 44 A and 54 A values in the same model order.
Installation Highlights: Panel and Thermal Layout
The D-frame construction of 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0 fixes the mounting format while current selection determines the thermal load.
Upright panel position
The IP20 / NEMA Type 1 enclosure is installed as a panel-mount drive with airflow maintained around it.
Coated internal assembly
Conformal coating is included in all three catalog configurations.
External option space
A HIM, communication adapter and braking resistor are not part of these complete codes and require separate accommodation when used.
Frequently Asked Questions
How should a designer select among 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
Use the motor duty and required current envelope: the three steps are 22 A, 27 A and 34 A with different one-minute and three-second limits.
What panel detail remains common across 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
All three use the Frame D panel-mount format, allowing the mechanical layout to stay common while the power-stage rating changes.
Why must normal-duty and heavy-duty ratings be kept separate for 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
The same catalog number has different supported motor-power steps under the two duty classes, so the duty selection changes the usable rating.
What must be planned if local operation is wanted on 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
The shipped configuration has a blank HIM position; provide a compatible HIM and the required access space separately.
How is a 4…20 mA reference applied to 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
Set the chosen standard-control analog input for current operation and scale the low and high reference values to the process signal.
What external item is still needed for repeated deceleration on 20AD022A0AYNANC0 / 20AD027A0AYNANC0 / 20AD034A0AYNANC0?
Although a brake IGBT is included, the braking resistor and thermal arrangement remain separately selected hardware.
