The Mitsubishi Electric FR-D820-3.7K-165-60 is a compact 200 V class variable frequency drive designed for precise and energy-efficient motor control in industrial applications. Part of the proven FR-D800 Series, this 3.7 kW inverter delivers reliable speed and torque regulation for induction and PM motors, making it a solid choice for OEMs, panel builders, and MRO teams across conveyors, pumps, fans, and packaging lines.

Engineered for productivity, it combines advanced magnetic flux vector control, PM sensorless vector, and V/F control to maintain stable performance from 0.2 to 590 Hz. The unit provides a rated output current of 16.5 A (ND) with a wide 170–264 V permissible input range on a 200–240 V 3-phase supply. Connectivity is built in: RS-485 for Modbus RTU and support for CC-Link IE Field Network Basic and CC-Link IE TSN streamline integration with PLCs and SCADA. Five digital inputs, two analog inputs, and both transistor and relay outputs enable flexible I/O, while a 4-digit LED display, USB Type-C port, and spring clamp terminals simplify setup and maintenance. Safe Torque Off (STO) and IP20 protection support machine safety and panel-level protection.

Whether for new builds or retrofit projects, the FR-D820 reduces commissioning time and ensures consistent, low-maintenance operation, helping you optimize energy use and uptime, with added peace of mind as it is supplied with a 1-year warranty for dependable coverage throughout the first year in service.
