The Allen-Bradley 25A-A4P8N114 is a AC adjustable-frequency drive — PowerFlex 523 for industrial control and automation applications.

What the Allen-Bradley 25A-A4P8N114 Delivers in a Single-Phase Package

The Allen-Bradley 25A-A4P8N114 is a PowerFlex 523 adjustable-frequency AC drive rated 0.75 kW (1 HP) for both normal duty and heavy duty, with 4.8 A continuous output current. It accepts 200…240V AC single-phase input and is supplied in an IP20 NEMA/Open Type enclosure with an integral EMC filter. For engineers specifying small motor control in oil and gas support systems, this drive combines a compact Frame A footprint with the control and communication features needed for dependable operation.

Key Specifications and Ratings

• Input voltage: 200…240V AC, 1-phase, with -15 % / +10 % tolerance and 47…63 Hz input frequency.
• Rated output: 0.75 kW (1 HP) normal duty and 0.75 kW (1 HP) heavy duty, 4.8 A continuous.
• Output frequency: 0…500 Hz programmable, with 0 V to rated motor voltage at terminals T1, T2 and T3.
• Control methods: Volts/Hertz, sensorless vector control and Economizer SVC.
• Carrier frequency: 2…16 kHz, with the published rating based on 4 kHz.
• Efficiency: 97.5 % typical.
• Operating temperature: -20…+50 °C without derating in vertical IP20 mounting, up to +60 °C derated, and up to +70 °C with the 25-FANx-70C control module fan kit.
• Dimensions: 152.0 H × 72.0 W × 172.0 D mm, weight 1.1 kg (Frame A).

The operating temperature range matters in field installations where panel temperatures rise. Because the drive is fan cooled and rated for -20…+50 °C without derating in the standard vertical IP20 arrangement, it suits enclosures that see seasonal swings. The optional fan kit extends the upper limit to +70 °C, which gives engineers headroom when cabinets are tightly packed.

Why the Input Voltage and Power Supply Design Matter

Single-phase 200…240V AC input simplifies power distribution where three-phase service is not available at the point of use. The drive tolerates input voltage from -15 % to +10 % and input frequency from 47…63 Hz, so it rides through the modest supply variations common on remote sites. A displacement power factor of 0.98 across the entire speed range keeps the load on the supply predictable. Power ride-through of 100 ms and logic control ride-through of 0.5 s minimum (2 s typical) help the drive maintain control during short supply dips. This unit also carries an integral EMC filter, which reduces the need for external filtering in many installations.

How Does the Drive Integrate With Control Systems?

The built-in RS-485 DSI port on the RJ45 terminal C1 supports Modbus RTU with function codes 03, 06 and 16. Network parameters include C123 [RS485 Data Rate] from 1200…38400 bit/s (default 9600), C124 [RS485 Node Addr] from 1…247, and C127 [RS485 Format] with RTU 8-N-1 as the default. For longer runs or more than 32 nodes, RS-485 repeaters may be needed. Only pins 4 and 5 of the RJ45 DSI connector are used for the network; the remaining pins carry power and other Rockwell Automation peripheral signals and must not be connected. Where EtherNet/IP, DeviceNet, PROFIBUS DP-V1 or PROFINET is required, the corresponding 25-COMM option card can be fitted. Integration Note: wiring into such networks may require an external gateway or connection module; confirm cables and gateways with the supplier.

Installation and Environmental Considerations

Frame A drives accept DIN-rail or screw mounting. The drive produces leakage current in the protective earthing conductor exceeding 3.5 mA AC and/or 10 mA DC, so the earthing conductor must comply with local regulations for high protective-earthing-current equipment. Relative humidity of 0…95 % non-condensing and an installation pollution degree of 1 or 2 are required for CE Low Voltage Directive compliance. The drive is not intended for public low-voltage networks supplying domestic premises; without additional mitigation, radio frequency interference is expected, and the installer is responsible for supplementary line filtering and enclosure measures. For IP30 / NEMA 1 / UL Type 1 protection, the 25-JBAx option kit is required.

Reliability in Oil and Gas Support Applications

Electronic motor overload protection provides class 10 protection according to NEC article 430 and motor over-temperature protection according to NEC article 430.126(A)(2). Overcurrent limits are 200 % hardware and 300 % instantaneous fault. The drive is c-UL-us Listed to UL 508C and CSA C22.2 No. 274, and it meets IEC 60721-3-3 level 3C2 for chemical and gases only, provided the ambient atmosphere contains no volatile or corrosive gases, vapors or dust. These characteristics make This unit a rugged choice for mission-critical auxiliary drives where dependable operation is expected. The drive is an active catalog number; please verify current lifecycle status and availability with PetroPartsOnline before ordering.
