Mitsubishi Electric FR-D720S-0.4K-CHT Frequency Inverter

The Mitsubishi Electric FR-D720S-0.4K-CHT is a compact 3‑phase frequency inverter designed for variable-speed control of AC motors in industrial and light‑duty automation systems. Commonly installed on small conveyors, HVAC fans, pumps, mixers, packaging lines, material handling systems, and general‑purpose automated machinery, it delivers smooth speed regulation, improved process control, and energy efficiency in a space‑saving module. This 0.4 kW (400 W) drive accepts 3‑phase input of 200–240 VAC (model dependent) and provides an output frequency range of 0.1–400 Hz. It uses V/f control with built‑in advanced functions, including PID control, DC braking, and torque boost, and supports an overload capacity of 150% for 1 minute. The unit includes built‑in fan cooling, IP20 protection, and panel‑mount installation with operating temperatures from −10 °C to 50 °C (storage −20 °C to 65 °C). Safety features cover overcurrent, overvoltage, and overheat protection, while optional RS‑485/Modbus communication enables integration with control networks.
