The Allen-Bradley 25A-A2P5N114 is a AC adjustable-frequency drive — PowerFlex 523 for industrial control and automation applications.

The Allen-Bradley 25A-A2P5N114 is a PowerFlex 523 adjustable-frequency AC drive rated 0.4 kW (0.5 HP) with a 200…240V AC single-phase input and 2.5 A continuous output current. It arrives as a Frame A, IP20 NEMA/Open Type unit with an integral EMC filter and a standard keypad interface module.

Not long ago, a small pump or fan on a remote well pad ran at one fixed speed, throttled by a valve or damper while the motor drew whatever current the load demanded. Operators accepted the waste because the alternative was a large, complex drive cabinet. Compact drives changed that calculation. The PowerFlex 523 family brought programmable acceleration, braking control and serial communications into a panel-mount envelope, and the 25A-A2P5N114 packages those functions for single-phase 200…240V AC installations.

What parameters define This unit?

The catalog number itself is a specification. In unit, the 25A prefix identifies the PowerFlex 523 member of the 520-series platform, A denotes the 200…240V AC voltage class, 2P5 the 2.5 A rating code, N the IP20 NEMA/Open enclosure, 1 the standard interface module, 1 the integral EMC filter and 4 the standard brake IGBT.

• Supply voltage: 200…240V AC, 1-phase, with -15 % / +10 % input voltage tolerance.
• Input frequency: 47…63 Hz.
• Rated output: 0.4 kW (0.5 HP) normal duty and 0.4 kW (0.5 HP) heavy duty at 2.5 A.
• Output frequency: 0…500 Hz programmable, with output voltage from 0 V to rated motor voltage.
• Overload: heavy duty 150 % of rated output current for up to 60 s and 180 % for up to 3 s.
• Efficiency: 97.5 % typical.
• Power dissipation: 29 W total at rated load and rated speed.
• Dimensions: 152.0 H × 72.0 W × 172.0 D mm, 1.1 kg.

How does the drive handle temperature and input power in the field?

Operating temperature is the parameter that most often decides where a drive can be mounted. In a vertical IP20/Open Type installation, This unit operates from -20…+50 °C without derating, up to +60 °C derated, and up to +70 °C when the 25-FANx-70C control module fan kit is fitted. Zero-stacking arrangements and NEMA 1 conversions change those limits, so the enclosure plan should be settled before the panel is built.

Input voltage tolerance of -15 % / +10 % and an input frequency window of 47…63 Hz let the drive ride through the supply variations common on remote sites. A 100 ms power ride-through and a logic control ride-through of 0.5 s minimum, 2 s typical, keep the control section alive through short interruptions. The DC bus trips at 405 V overvoltage and 190 V undervoltage, which correspond to 290 V AC and 150 V AC incoming line values for this voltage class.

Because the unit produces leakage current above 3.5 mA AC and/or 10 mA DC in the protective earthing conductor, the earthing arrangement must follow local regulations for high protective-earthing-current equipment. The integral EMC filter supports emission compliance, yet the drive is not intended for public low-voltage networks supplying domestic premises without additional mitigation.

Which control and communication options are available?

Control is sinusoidal PWM with Volts/Hertz, sensorless vector control and Economizer SVC. Speed regulation reaches ±1 % of base speed across a 60:1 range in V/Hz, and ±0.5 % across a 100:1 range in SVC modes. Four independently programmable acceleration and deceleration times each span 0…600 s in 0.01 s increments.

I/O includes one dedicated Stop input plus four programmable digital inputs, one isolated analog input (0…10V DC or 4…20 mA), one programmable Form C relay output and one non-isolated analog output. A pulse train input shares one programmable digital input and accepts 0…100 kHz.

The built-in RS-485 DSI port on RJ45 terminal C1 supports Modbus RTU function codes 03, 06 and 16, with data rates from 1200…38400 bit/s and node addresses 1…247. Only pins 4 and 5 of that connector carry the network; the remaining pins must not be connected. For EtherNet/IP, DeviceNet, PROFIBUS DP-V1 or PROFINET, the 520-series communication adapters install as option cards, and PowerFlex 523 accepts one card.

Where does this drive fit in oil and gas operations?

The 0.4 kW rating suits small pumps, fans, mixers and metering skids where a single-phase 200…240V AC feed is available. Sensorless vector control holds speed under changing load, which helps on transfer pumps that see varying viscosity or head pressure. The integral brake IGBT, paired with an external brake resistor, supports controlled stops on high-inertia loads. In panel-mounted installations, the IP20 open type suits a protected enclosure, while the 25-JBAx option kit converts the drive to IP30 / NEMA 1 / UL Type 1 for a guarded cabinet face.

For harsh environments, the drive complies with IEC 60721-3-3 level 3C2 for chemical and gases only, and the ambient atmosphere must not contain volatile or corrosive gases, vapors or dust. Where those conditions exist, the installation should be planned around a suitable enclosure.

How should the drive be installed and maintained?

Frame A accepts DIN-rail or screw mounting. Keep the vertical orientation and the published clearances, and separate network wiring from power wires by at least 0.3 m (1 ft), crossing only at right angles. Fit 120 Ω termination resistors at each end of the RS-485 cable, and add repeaters for long runs or more than 32 nodes.

Maintenance is inspection-led: check fan operation, clear dust from the heatsink and verify terminal torque at scheduled shutdowns. The electronic motor overload protection provides class 10 protection under NEC article 430, so the drive's own settings should match the motor nameplate. Please verify current lifecycle status and availability with PetroPartsOnline before ordering.

Frequently asked questions

What input voltage does This unit require?

The Allen-Bradley unit accepts a 200…240V AC single-phase input with -15 % / +10 % tolerance and 47…63 Hz input frequency.

Can This unit run a three-phase motor?

Yes. The drive delivers three-phase output at terminals T1, T2 and T3, with output voltage from 0 V to rated motor voltage and output frequency programmable from 0…500 Hz.

Does this drive include an encoder interface?

No. No encoder option is published for the PowerFlex 523, so speed regulation relies on V/Hz or sensorless vector control rather than closed-loop feedback.

What is the maximum ambient temperature without derating?

In a vertical IP20/Open Type installation, the Allen-Bradley unit operates from -20…+50 °C without derating, and up to +70 °C with the 25-FANx-70C control module fan kit.

Which communication protocols are built in?

The drive provides one RS-485 DSI port supporting Modbus RTU. EtherNet/IP, DeviceNet, PROFIBUS DP-V1 and PROFINET require the corresponding 520-series communication adapter card.
