Allen-Bradley PowerFlex 753 20F14NF046JN0NNNNN AC Drive – Technical Specifications & FAQ

FAQ

Q1: What is the Allen-Bradley 20F14NF046JN0NNNNN?

• It is an Allen-Bradley PowerFlex 753 AC drive designed for industrial motor control and common-bus applications.

Q2: What is the power rating of the 20F14NF046JN0NNNNN?

• The drive is rated at 37 kW for normal-duty operation and 30 kW for heavy-duty operation. The normal-duty continuous output current is 46 A.

Q3: What voltage does this PowerFlex 753 model support?

• This model belongs to the 690 V AC class and is designed for a nominal 932 V DC common-bus input.

Q4: What is the frame size of this drive?

• The 20F14NF046JN0NNNNN uses Frame 6. The Frame 6 platform is used for several higher-power PowerFlex 753 configurations.

Q5: Does the 20F14NF046JN0NNNNN include filtering?

• Yes. The specified J configuration includes filtering and the common-mode jumper installed.

Q6: Does this model include an internal dynamic braking transistor?

• No. The specified configuration does not include an internal dynamic braking transistor. An external braking solution may be required for applications with substantial regenerative energy.

Q7: Does the drive come with a Human Interface Module?

• No. This configuration is supplied without a HIM. A compatible HIM can be added separately for local programming, parameter adjustment, and monitoring.

Q8: What are the dimensions and weight of the 20F14NF046JN0NNNNN?

• The approximate Frame 6 dimensions are 665.5 × 308 × 346.4 mm (H × W × D), and the drive weighs approximately 38.6 kg. These figures refer to the drive itself rather than its shipping package.
