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

Rated at 18.5kW / 37A (part number 25A-D037N114), the PowerFlex 523 from Allen-Bradley delivers reliable variable speed motor control for general-purpose applications across Australia. Its straightforward commissioning, proven Rockwell Automation reliability, and competitive price point make it the natural starting point for new drives installations and like-for-like replacements.

Standard I/O includes analogue speed reference input (0–10V or 4–20mA), digital inputs for run/direction/speed preset commands, and a relay output for run/fault indication. This covers the majority of simple drive applications without requiring additional I/O hardware, simplifying panel design and reducing wiring labour.

• Power: 18.5kW, current: 37A at 415V AC input
• Single option slot: EtherNet/IP, DeviceNet, or PROFIBUS adapters available
• Removable I/O terminal block for simplified drive replacement
• Digital inputs for run, direction, and preset speed selection
• Relay output for run/fault status indication
• Rockwell Automation part: 25A-D037N114

At 18.5kW, the PowerFlex 523 provides cost-effective variable speed control for pumping stations, ventilation systems, and material handling equipment. The drive’s built-in PID controller handles pressure-controlled pump applications, and its seven digital preset speeds support multi-stage process requirements without requiring an external controller for speed reference generation.
