Mitsubishi FR‑A842‑12120‑F Brand New FR‑A842 VFD

Product Overview

The Mitsubishi FR‑A842‑12120‑F is a Brand New, high-capacity Variable Frequency Drive (VFD) from the flagship FR-A800 Series. This 400V class inverter is a powerhouse designed for massive industrial loads, offering unparalleled motor control and reliability for large-scale applications. The "F" designation indicates a specialized configuration (often related to mounting or cooling fan specifications), while the drive itself utilizes Mitsubishi's "Real Sensorless Vector Control" to achieve high torque and precision without requiring an encoder. As a Brand New unit, it represents the pinnacle of Mitsubishi's power electronics, featuring advanced predictive maintenance, integrated safety, and massive scalability for heavy industry.

Key Features

• High-Power 400V Control: Optimized for large 3-phase 380-500V industrial motors, providing massive current output for heavy-duty (HD) and normal-duty (ND) cycles.
• Real Sensorless Vector Control (RSVC): Achieves exceptional speed and torque accuracy (200% starting torque at 0.3Hz) without the need for an external encoder.
• Advanced Safety Integration: Built-in Dual-channel Safe Torque Off (STO) functionality meets SIL3 and PLe standards, ensuring the highest level of operator and machine safety.
• Intelligent Energy Management: Features energy-saving monitors and algorithms that optimize excitation current to reduce electrical consumption by up to 10% under partial loads.
• Predictive Maintenance: Monitors the health of internal power components (capacitors and fans) and the motor's load characteristics to prevent unplanned downtime.
• Built-in PLC: Features a high-capacity 6k-step PLC for managing complex system logic, I/O coordination, and communication protocols directly at the drive level.
