📦 Product Overview

The INOVANCE MD520-4T18.5B is a high-power compact variable frequency drive delivering 18.5 kW (25 HP) for heavy-duty three-phase AC motor control. As the top-tier model in the MD520 series, it combines advanced sensorless vector control (SVC) with a built-in braking unit and PID process control. Engineered for large industrial pumps, high-capacity fans, heavy-duty conveyors, compressors, and demanding OEM machinery, the MD520-4T18.5B delivers exceptional torque, efficiency, and connectivity for the most challenging industrial environments at an outstanding value proposition.

✨ Product Advantages
  • Compact Vector Drive — Advanced SVC delivers 150% starting torque at 0.5 Hz with ±0.5% speed accuracy for precision motor regulation under the heaviest loads
  • High Torque Inverter — Exceptional low-speed torque performance ensures smooth, stall-free startup of large machinery and high-inertia industrial loads
  • Built-in PID Process Control — Integrated closed-loop controller for precise flow, pressure, level, and temperature regulation without external PLC or PID modules
  • Built-in Braking Chopper — Integrated dynamic braking unit supports fast, controlled deceleration and precise stopping for rapid-cycle industrial applications
  • Industrial-grade Protection — Multi-layer safeguards including overcurrent, overvoltage, undervoltage, overload, phase-loss, short-circuit, and overtemperature protection
  • Full Automation Integration — Rich multi-function digital/analog I/O plus onboard RS485 Modbus RTU for seamless PLC, HMI, and SCADA connectivity
  • Energy Optimization — Built-in energy-saving algorithm automatically reduces power consumption under light-load conditions for lower operating costs
  • Rugged Industrial Construction — Conformal-coated PCB, independent air duct cooling, detachable multi-language keypad, and wide -10°C to 50°C operating range
