FR-D740-1.5K FREQROL-D700 1.5kW 3-Phase Inverter 400V | Mitsubishi Electric

The Original New Mitsubishi Electric FR-D740-1.5K is a compact, high-performance inverter from the FREQROL-D700 series, designed for precise speed control of three-phase induction motors. Rated at 1.5 kW (2 HP) with a 380–480 V AC three-phase input, it delivers 3.6 A rated output current and a 0.2–400 Hz output frequency range. The drive features general-purpose magnetic flux vector control for high starting torque (150% at 1 Hz), built-in Modbus RTU and RS-485 communication, and a Safe Torque Off (STO) function compliant with SIL2/PLd. The spring-clamp control terminals enable tool-free wiring, reducing installation time. IP20 protection, built-in 4-digit LED display, and compact dimensions make it suitable for space-constrained control panels in packaging, material handling, and general industrial automation.
