📦 Product Overview

The INOVANCE MD520-4T15B is a high-power compact variable frequency drive delivering 15 kW (20 HP) for demanding three-phase AC motor control in heavy-duty industrial applications. As the highest-rated model in the MD520 series, it combines advanced sensorless vector control (SVC) with a built-in braking unit and PID process control. Designed for large pumps, industrial fans, heavy conveyors, compressors, and high-power OEM machinery, the MD520-4T15B delivers exceptional torque performance, energy efficiency, and system connectivity in a space-optimized package at an outstanding price-performance ratio.

✨ Product Advantages
  • Compact Vector Drive — Advanced SVC with 150% starting torque at 0.5 Hz and ±0.5% speed accuracy ensures reliable performance for the most demanding loads
  • High Torque Inverter — Exceptional low-speed torque output guarantees smooth, stall-free startup of heavy-duty machinery and high-inertia loads
  • Built-in PID Process Control — Integrated closed-loop controller for flow, pressure, level, and temperature regulation eliminates external controller costs
  • Built-in Braking Chopper — Integrated dynamic braking unit enables fast deceleration and precise stopping for rapid-cycle applications without external hardware
  • Industrial-grade Protection — Multi-layer safeguards including overcurrent, overvoltage, undervoltage, overload, phase-loss, short-circuit, and overtemperature protection
  • Seamless Network Integration — Multi-function digital/analog I/O plus RS485 Modbus RTU for effortless PLC, HMI, and SCADA connectivity
  • Energy-efficient Operation — Auto energy optimization reduces power consumption during partial-load conditions, lowering lifetime operating costs
  • Rugged & Reliable Design — Conformal-coated PCB, independent air duct cooling, and detachable multi-language keypad for demanding industrial environments
