📦 Product Overview

The INOVANCE MD520-4T3.7B is a compact mid-power variable frequency drive delivering 3.7 kW (5 HP) for precision speed control of three-phase asynchronous AC motors. As part of the MD520 series, it combines sensorless vector control (SVC), a built-in braking unit, and PID process control in a space-saving design. Bridging the gap between micro and general-purpose drives, the MD520-4T3.7B is ideal for OEM machinery, pump and fan systems, conveyors, and light industrial automation applications demanding reliable performance with an excellent cost-performance ratio.

✨ Product Advantages
  • Compact Vector Drive — Sensorless vector control delivers 150% starting torque at 0.5 Hz with ±0.5% speed accuracy in a compact footprint
  • Precision Motor Control — 1:100 speed regulation range with auto-tuning ensures optimal performance across diverse pump, fan, conveyor, and machinery loads
  • Built-in PID Process Control — Integrated closed-loop controller for flow, pressure, and temperature regulation without external PLC programming
  • Built-in Braking Unit — Integrated braking chopper enables fast, controlled deceleration for rapid-stop applications without external hardware
  • Flexible I/O Configuration — Multi-function digital inputs, analog I/O, and relay outputs support diverse machine control architectures
  • RS485 Modbus Connectivity — Built-in Modbus RTU interface for seamless integration with PLCs, HMIs, and industrial automation networks
  • Comprehensive Protection — Overcurrent, overvoltage, undervoltage, overload, phase-loss, and short-circuit safeguards ensure long service life
  • User-friendly Operation — Intuitive detachable keypad with multi-language display and quick-start commissioning minimizes setup time
