📦 Product Overview

The INOVANCE MD520-4T0.7B is an ultra-compact micro variable frequency drive delivering 0.75 kW (1 HP) for precision speed control of small three-phase asynchronous AC motors. As part of Inovance's entry-level MD520 series, it brings sensorless vector control (SVC) to space-constrained applications with a remarkably small form factor. The built-in braking unit, silent fanless operation, and plug-and-play simplicity make it the perfect choice for OEM machine builders and light industrial applications where compact size, reliability, and cost-effectiveness are essential.

✨ Product Advantages
  • Compact Vector Drive — Full sensorless vector control packed into an ultra-small footprint, enabling high-precision motor regulation in tight spaces
  • Precision Motor Control — ±0.5% steady-speed accuracy with 1:100 speed regulation range delivers consistent, reliable motor performance
  • Built-in Braking Unit — Integrated braking chopper enables fast, controlled deceleration for applications requiring rapid stops without external hardware
  • Silent Fanless Operation — Natural cooling design eliminates fan noise, making it ideal for noise-sensitive environments such as laboratories and clean rooms
  • Quick & Easy Setup — Intuitive keypad with multi-language display and auto-tuning function minimizes commissioning time and complexity
  • Flexible Control I/O — Multi-function digital inputs and analog I/O accommodate diverse small-machine control needs without expansion modules
  • Energy-saving Optimization — Automatic energy-saving mode reduces power consumption during partial-load operation, lowering lifetime operating costs
  • Reliable Protection — Overcurrent, overvoltage, overload, and short-circuit protection safeguard both drive and motor for trouble-free operation
