Overview
The Allen-Bradley 25B-B032N104 is a PowerFlex 525 AC drive delivering robust variable frequency drive (VFD) control for motors up to 10 HP (7.5 kW). Designed for 200–240 VAC three-phase input with 32.2 A output current, this Frame D drive combines flexible motor control with modern industrial communication protocols. Built-in EtherNet/IP and embedded safety features make it suitable for facility-wide automation networks and SIL 2 / PL d applications.
