Allen-Bradley 20AC3P5A0AYNNNC0 — PowerFlex 70 AC Drive, 3.5A / 1.5 kW

AB · PowerFlex 70 · 20AC Frame A · Conformal Coat · In stock

The 20AC3P5A0AYNNNC0 is a sealed, new-old-stock unit from the Allen-Bradley PowerFlex 70 family — a compact 208–480V three-phase AC drive rated 3.5 A continuous (approximately 1.5 kW / 2 HP at 400V and 0.75 kW / 1 HP at 230V). It ships in a Frame A IP20 NEMA open chassis, ships with the Enhanced Control firmware (AY), no integral HIM (A0), no brake IGBT (N), no communication option (NN), and conformal-coated boards (C0) for harsh-environment cabinets. It is widely deployed in factory automation cells, OEM skids, and process auxiliaries alongside Allen-Bradley ControlLogix and CompactLogix controllers.

Key Technical Specifications

Application Scenarios — Where It Fits

The 3.5A / 1.5 kW rating puts the 20AC3P5A0AYNNNC0 squarely in the low-power auxiliary class — the drive engineers reach for when a 1–2 HP motor needs to be precisely speed-controlled inside a larger Logix-coordinated cell. Typical placements include:

• Pumps & fans — HVAC booster sets, chiller water pumps, exhaust fans with quadratic torque loads.
• Conveyors & small material-handling — indexing belts, diverters, and sortation drives on packaging lines.
• Mixers, agitators, and small process skids — water-treatment dosing skids, food & beverage ingredient feeders, pilot-plant reactors.
• OEM machine builder — machine builders who standardize on Logix controllers (CompactLogix / ControlLogix) and want a single family of drives from Allen-Bradley all the way down to fractional HP.
• Legacy system repair — drop-in replacements for retired PowerFlex 70 units still in service in plants originally commissioned in the 2000s.

Although the brief is AB PowerFlex 70, the typical control cabinet still houses a mix of Siemens HMI panels, Mitsubishi servo axes, Omron sensors, and Schneider motor-protection breakers. Multi-brand cabinets are exactly the environment KOEED’s China Sourcing Company is set up to quote BOM-by-BOM.

Integration & Wiring Notes

The NN position in the catalog string means no communication option is factory-installed. Pairing this drive with Logix typically requires one of:

• 20-Comm-E — EtherNet/IP module (the most common path to a CompactLogix L30ER or a 1756-EN2T scanner on a ControlLogix chassis).
• 20-Comm-C — ControlNet module, for older ControlLogix cells on 1756-CN2.
• 20-HIM-A6 — remote Human Interface Module if you need a panel-mount keypad in the cabinet door.

Power terminals follow the standard PowerFlex 70 Frame A layout: L1/L2/L3 input at the top, U/V/W output at the bottom, and a dedicated PE stud on the heatsink. Brake resistor terminals (BR+/BR−) are present on the power block but unconnected on this build because the N (no brake IGBT) option was specified. If your application needs dynamic braking, order the equivalent catalog string ending in A0AYNNNC0 → swap the N for the brake IGBT variant — or use an external brake resistor controlled by a separate contactor.

Control wiring uses the removable TB on the front face: digital inputs (Start, Stop, Enable, two programmable), one analog input (±10V / 0–20 mA), one analog output, and one Form-C relay. For floating references, tie analog common to chassis ground at the drive end to avoid ground-loop noise when long analog runs run parallel to VFD output cables.

Installation & Commissioning Tips

• Mounting clearance. Frame A needs 50 mm top, bottom, and side clearance in a vented cabinet. Derate output by 1% per °C above 40 °C ambient.
• Input protection. Use a fast-acting semiconductor fuse or a listed molded-case circuit breaker on the line side. The conformal coat (C0) does not replace the need for IP54 cabinet sealing in wash-down areas.
• Grounding. PE conductor should be sized per local code and terminated directly to the drive’s PE stud — not piggy-backed on the motor cable shield.
• Motor cable. Use symmetrical VFD-rated cable (e.g. Olflex Servo 2YSLCY or equivalent) and keep the run under 50 m to stay inside the CE EMC envelope with the integrated filter.
• Auto-tune. Run a static and rotating autotune through Connected Components Workbench (CCW) or Studio 5000 once the motor is coupled — this drive supports both sensorless vector and V/f and benefits from a measured stator resistance.
• Firmware match. When migrating a spare into a cabinet with existing PowerFlex 70 units, compare firmware major/minor on the nameplate sticker. PowerFlex 70 firmware v6 onwards added some CIP safety and indexed-positioning features; v11+ is the current standard.
• Diagnostic tools. When the drive throws an Fxx fault you don’t recognize, our PLC Error Code Database covers Allen-Bradley, Siemens, Mitsubishi, and Omron codes, and the AI Diagnostic Tool can read a nameplate photo and suggest a cross-reference.
• Signal conversion. If you need to scale analog I/O between Logix and the drive, the PLC Hex to Float Converter helps decode 16-bit raw counts to engineering units without dragging a laptop onto the floor.

Procurement, Warranty & Lead Time

KOEED keeps the 20AC3P5A0AYNNNC0 on the shelf as a sealed AB unit — shelf-life is the only concern with conformal-coated spares, and we rotate stock with the same FIFO discipline we apply to all nine brands we cover. Standard lead time is same-day dispatch for orders confirmed before 14:00 (business days) via DHL / FedEx / UPS, with full tracking forwarded to the buyer’s email. For project buys of 10+ units, ask for a written lead-time commitment on letterhead.

Pricing follows the KOEED quote-driven model: send the part number and quantity to Moritta@KOEED.COM and we return availability and price within 24 hours on business days. If you’re rebuilding an entire machine, send the BOM and we’ll quote the lot — including the PowerFlex 523 / PowerFlex 525 / PowerFlex 4 variants you may be using elsewhere in the line.

KOEED is an independent multi-brand distributor — not an Allen-Bradley subsidiary — and we source the same way for Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, and KEYENCE. Every drive ships with a 12-month functional warranty covering DOA and in-warranty failure; out-of-warranty repairs can be arranged through our bench-test facility. Payment terms, proforma invoices, and country-of-origin certificates are provided on request.

Questions before you order? Email Moritta@KOEED.COM or use the BOM request form — KOEED also handles CompactLogix, ControlLogix, SLC 500, PanelView, and the rest of the Allen-Bradley catalog alongside Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, and KEYENCE lines.
