📦 Product Overview

The INOVANCE MD520-4T22B is the most powerful model in the MD520 series, delivering 22 kW (30 HP) for the most demanding three-phase AC motor control applications. Combining advanced sensorless vector control (SVC) with a built-in braking unit and PID process control, it is purpose-built for large industrial pumps, high-capacity fans, heavy-duty conveyors, compressors, and high-power OEM machinery. With exceptional torque performance, robust protection, and seamless automation integration, the MD520-4T22B delivers uncompromising industrial drive performance at an outstanding value.

✨ Product Advantages
  • Compact Vector Drive — Advanced SVC technology with 150% starting torque at 0.5 Hz and ±0.5% speed accuracy for precision control under the most demanding loads
  • High Torque Inverter — Exceptional low-speed torque output ensures smooth, reliable startup of the heaviest machinery and highest-inertia industrial loads
  • Built-in PID Process Control — Integrated closed-loop controller enables precise flow, pressure, level, and temperature regulation without external hardware
  • Built-in Braking Chopper — Integrated dynamic braking unit supports fast, controlled deceleration and precise stopping for rapid-cycle industrial processes
  • Industrial-grade Protection — Comprehensive multi-layer safeguards including overcurrent, overvoltage, undervoltage, overload, phase-loss, short-circuit, and overtemperature protection
  • Full Automation Connectivity — Rich multi-function digital/analog I/O plus onboard RS485 Modbus RTU for seamless PLC, HMI, and SCADA system integration
  • Energy-efficient Design — Built-in energy optimization automatically reduces power consumption during partial-load operation for significant long-term savings
  • Extreme-duty Construction — Conformal-coated PCB, independent air duct cooling, detachable multi-language keypad, and -10°C to 50°C operating range
