📦 Product Overview

The INOVANCE MD520-4T5.5B is a high-power compact variable frequency drive delivering 5.5 kW (7.5 HP) for reliable speed control of three-phase asynchronous AC motors. Positioned at the upper end of the MD520 series, it combines sensorless vector control (SVC) with a built-in braking unit and PID process control in a space-efficient design. Purpose-built for OEM machine builders, pump systems, fans, and general industrial automation, the MD520-4T5.5B offers professional-grade motor control with exceptional ease of use and outstanding 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 form factor
  • Precision Motor Control — 1:100 speed regulation range with auto-tuning ensures optimal performance across pumps, fans, conveyors, and machinery
  • Built-in PID Process Control — Integrated closed-loop controller regulates flow, pressure, and temperature without external PLC programming or hardware
  • Built-in Braking Unit — Integrated braking chopper enables fast, controlled deceleration for applications requiring rapid stops without external resistors
  • Flexible I/O Configuration — Multi-function digital inputs, analog I/O, and relay outputs accommodate diverse machine control architectures
  • RS485 Modbus Connectivity — Built-in Modbus RTU interface for seamless integration with PLCs, HMIs, and factory automation networks
  • Comprehensive Protection — Overcurrent, overvoltage, undervoltage, overload, phase-loss, and short-circuit safeguards ensure maximum uptime
  • User-friendly Operation — Intuitive detachable keypad with multi-language display and quick-start commissioning for minimal setup time
