Allen Bradley 22A-A1P5N114: Specs, Features & Buying Guide

If you maintain or build around Rockwell equipment, the part number 22A-A1P5N114 turns up more often than its size suggests. It is a PowerFlex 4 AC drive rated at 0.2 kW (0.25 HP) with a 1.5 A output. It is built for 200–240 V single-phase input. The N114 suffix matters because it carries an integral EMC filter and a brake IGBT, which changes both installation and compliance planning.

This guide covers what the catalog number means and the specifications you can hold a supplier to. It looks at the applications that genuinely fit a drive this small. It also compares nearby catalog numbers and closes with a practical buying checklist. Whether you are replacing a failed unit, quoting a machine upgrade, or planning a single-phase retrofit, the checklist here applies. The content draws on Rockwell’s published technical data and field experience with single-phase drive retrofits, not marketing copy.

What the Catalog Number Tells You

Rockwell encodes most of a drive’s identity into the catalog number. Read it once and you can verify quotes, check replacements, and avoid ordering the wrong suffix.

Two decoding mistakes are common in the field. First, “A” gets read as 120 V; it is not. The 120 V class uses “V,” so a 120 V equivalent is 22A-V1P5N104. Second, the output is three-phase 0–230 V while only the input is single-phase. The drive converts single-phase mains into three-phase motor power, which explains its presence on retrofit jobs with no three-phase supply.

The rating code also exposes sizing philosophy. The 1P5 figure is 1.5 A continuous output current, not input current. Rockwell lists input current separately; on this frame it runs near half the output rating under load. Feeders sized from the output figure are simply wrong. When a quote arrives, decoding the suffix yourself is the fastest sanity check. It takes thirty seconds and prevents expensive mistakes at the receiving dock.

22A-A1P5N114 Specifications at a Glance

The table below consolidates the values Rockwell publishes for this exact variant.

Two numbers deserve context before you compare drives. The 1.5 A rating is continuous output at the terminals; match it to the motor nameplate FLA, not the nameplate HP. The overload curve covers starting and brief shock loads, so it is not a license to run an oversized motor.

Efficiency matters most on continuous duty. At 0.25 HP the absolute energy saving is modest; the real value sits in process control. Soft starts, adjustable flow, and reduced mechanical shock matter more than the kilowatt-hours. On a retrofit feeder with only single-phase available, this drive makes a fixed-speed three-phase motor controllable. The motor itself does not change.

The RS-485 port makes PLC integration straightforward. Most installations use Modbus RTU for speed reference and status. OEMs that need higher-level networking add a 22-COMM module for EtherNet/IP, DeviceNet, Profibus DP, or BACnet.

Where a 0.25 HP Single-Phase Drive Earns Its Keep

Drives this size appear in three recurring places: light conveyor segments, small fans and pumps, and OEM machine sub-assemblies. The common thread is simple speed control, not zero-speed torque.

Conveyor segments under roughly 10 m with light product load fit the 0.25 HP envelope comfortably. Operators trim speed between line sections using the keypad potentiometer or a 0–10 V signal. That replaces mechanical variators and their regular maintenance.

For fans and pumps, the drive replaces contactor starters. Soft acceleration removes belt slip and water hammer; running at partial speed cuts input power roughly with the cube of speed. Payback is small at this power level, so treat energy saving as a bonus rather than the business case.

OEM builders pick the frame A footprint when panel space is tight. Panel-mount units sit beside contactors, and flange-mount variants save panel depth. The filtered N114 also simplifies CE planning for machines exported to Europe, because the filter is already inside the drive. Procurement teams often order these drives by suffix alone. A short spec note covering input voltage, filter requirement, and motor FLA prevents most mismatches before the purchase order goes out.

What does not fit this drive: high-inertia loads, frequent reversing, or any motor whose starting demand exceeds the overload curve. A 0.25 HP drive cannot start a loaded 0.5 HP pump. Size by current, and derate above 40 °C when drives mount side by side.

22A-A1P5N114 vs Nearby Catalog Numbers

Since buyers search by exact part number, the practical question is usually which suffix a given project needs. For the Allen Bradley 22A-A1P5N114, the comparison below covers the immediate family and the natural step up.

Filter choice drives most decisions. The integral “S-type” filter brings conducted emissions in line with CE requirements for typical industrial environments. Machines bound for the EU should use the filtered variant. North American builders without an EMC requirement routinely save cost with the N104.

Brake IGBT only matters if you plan dynamic braking with an external resistor. Small fans and conveyors coast down acceptably. High-inertia loads that must stop on command need the brake IGBT plus a correctly sized braking resistor.

Step-up logic is equally direct. If motor FLA exceeds 1.5 A, or if repeated starts need overload headroom, move to the A2P3 at 2.3 A. Running a 0.5 HP motor from a 0.25 HP drive is the most common sizing error seen in the field.

What to Check Before You Buy

Once the suffix is right, buying becomes a verification exercise. Four checks separate a smooth order from a costly swap.

1. Condition and authenticity. PowerFlex 4 units remain in service worldwide, so surplus stock is active. Confirm new, factory-sealed stock versus used or refurbished, and inspect serial numbers and enclosures for signs of relabeling.
2. Warranty and support. Rockwell’s standard warranty is one year. Ask whether the warranty is manufacturer-backed or reseller-backed, and who handles an RMA if the unit fails at first power-up.
3. Label and documentation. The CE claim travels with the filtered variant and the nameplate. Request a label photo so the suffix and approvals are visible before shipment.
4. Lead time. Frame A single-phase units are commonly stocked, but suffix variants lag. If the exact filter/brake combination is not on the shelf, sampling delays may occur. Confirm the suffix against the project schedule.

Distributors that specialize in Rockwell drives usually list new stock with transparent pricing. SieSourceHK, for example, carries the PowerFlex 4 line across 120/240/480 V classes and lists the 22A-A1P5N114 as new inventory with warranty. That is what a buyer wants to see: a named condition, a stated warranty, and a traceable part number rather than a vague “compatible” listing.

Price sanity matters as much as technical fit. New, factory-stock PowerFlex 4 units sit in a fairly narrow band. A deal far below market usually signals used stock, an older production lot, or a missing suffix. Ask the seller to state the condition and warranty in writing before payment.

Field Notes: Wiring, Mounting, and First Power-Up

Small drives punish small mistakes. These points come from the PowerFlex 4 documentation and repeated commissioning experience.

• Follow the published line-side fusing and SCCR tables. Keeping them intact preserves the panel’s short-circuit rating.
• Size the feeder for input current, not output current. On this frame, input current runs near half the output rating under load.
• Mount for airflow. Zero-gap side-by-side mounting is allowed up to 40 °C; above that, maintain spacing between units.
• Separate control wiring from power wiring. RS-485 runs stay reliable when ducted away from motor leads.
• Program the nameplate data before the first run. V/Hz control with slip compensation only performs when the drive knows motor FLA and base frequency.

When replacing another brand, review the old wiring scheme against the new terminal layout before energizing. Most commissioning delays on these drives trace back to assumptions carried over from previous equipment.

FAQ

Is the 22A-A1P5N114 a single-phase or three-phase drive?

Input is 200–240 V AC single-phase; output is 0–230 V AC three-phase. It runs a standard three-phase motor from a single-phase feeder.

What size motor can it drive?

Up to 0.2 kW (0.25 HP) continuous, provided the motor’s full-load current is 1.5 A or less. For 0.5 HP motors, step up to the 22A-A2P3N114 (2.3 A).

Does the N114 include an EMC filter?

Yes. The “1” in the filter position means an integral “S-type” filter for CE compliance. The similar-looking 22A-A1P5N104 has no filter.

Can the N114 replace a 22A-A1P5N104?

Mechanically and electrically, yes — same frame, terminals, and ratings. Confirm the EMC requirement first, because the N114 adds the filter and costs more.

Is the brake IGBT included?

Yes. The trailing “4” means the brake IGBT is fitted; a “3” omits it. Pair it with an external braking resistor only when the load needs controlled deceleration.

What should I verify when buying from a reseller?

Condition (new versus used), exact suffix, a label photo showing approvals, warranty terms, and who handles returns or an RMA.
