PowerFlex 523

The Allen-Bradley PowerFlex 523 (bulletin prefix 25A) is a compact AC variable-frequency drive designed for general-purpose speed control applications. All catalog numbers follow a structured format: the 25A prefix identifies the PowerFlex 523 family, the next letter encodes voltage and phase (V = 120V 1-phase, A = 240V 1-phase, B = 240V 3-phase, D = 480V 3-phase, E = 600V 3-phase), followed by an output-current code where P substitutes for a decimal point (e.g., 2P5 = 2.5 A). The trailing digits indicate enclosure (N = IP20 open chassis), HIM interface, and EMC filter status — suffix 104 means no internal filter, while 114 includes an integrated EMC filter to EN 61800-3. Popular in-stock units include the 25A-V1P6N104 (0.25 HP, 120V 1-phase), 25A-A8P0N104 (2 HP, 240V 1-phase), and 25A-B2P5N104 (2.5 A, 240V 3-phase). Accessories such as the 25A-CTM1 control module and 25A-CTMFC1 front cover are also available. See the PowerFlex 520-Series Technical Data Sheet (520-TD001) for complete ratings and wiring details.
