Allen Bradley PowerFlex VSD 18.5kw ND, 15kw HD, 37amp

Rockwell Automation’s PowerFlex 525 variable speed drive in 18.5kW / 37A configuration (part 25B-D037N114) sets a new benchmark for compact drives in Australian industrial applications. Dual-port EtherNet/IP enables linear and Device Level Ring (DLR) topologies without an unmanaged switch, while on-board Safe Torque Off satisfies SIL 2 / PLe safety requirements without additional hardware.

Safe Torque Off (STO) to SIL 2 / PLe is provided as a standard hardware feature, with no software configuration required. The STO function prevents torque generation in the motor without removing main power from the drive, enabling faster restart after a safety event compared to traditional contactor-based isolation methods.

• Power: 18.5kW, current: 37A at 415V AC input
• Studio 5000 Add-On Profile (AOP) — native Logix integration
• Removable I/O terminal block for fast field drive replacement
• Linear EtherNet/IP daisy-chain — no switch required
• IP20 enclosure; optional DIN-rail or panel-mount
• Rockwell Automation part: 25B-D037N114

The 18.5kW PowerFlex 525 is a cost-effective option for industrial pump and fan applications where full EtherNet/IP connectivity is required but the additional option-slot flexibility of the 753 or 755 is not justified. InstroDirect’s parallel-import pricing makes this an even more attractive proposition for budget-conscious projects with Logix-based control architecture.

As a parallel importer, InstroDirect provides the PowerFlex 525 at prices well below the authorised distributor channel — same genuine Rockwell Automation product, lower cost. Australian stock, fast freight nationwide. Request a quote today.
