Mitsubishi FR-D740-120-NA Inverter

Core Performance & Industrial Application

The Mitsubishi Electric FR-D740-120-NA is a FREQROL D700 series general-purpose variable frequency drive for three-phase 380-480V supply.

It delivers 150%/1Hz high starting torque under magnetic flux vector control for fan, pump and conveyor motor speed control.

It supports 0.2~400 Hz output frequency range with analog 0-10V / 4-20mA speed reference and built-in PID function.

It provides overload current rating 150% for 60 s (inverse-time) and built-in EMC and surge protection circuits.

The NA suffix denotes the North American specification version with terminal naming L1/L2/L3.

It is widely used as spare replacement for legacy D700 VFDs in machine and fan-pump control.
