Mitsubishi FR‑A842‑10940‑F Brand New FR‑A842 VFD

Product Overview

The Mitsubishi FR‑A842‑10940‑F is a Brand New, high-capacity Variable Frequency Drive (VFD) from the premier FR-A800 Series. This 400V class industrial inverter is designed to drive massive motor loads with extreme precision and reliability. The "F" designation signifies a specialized configuration (typically referring to specific cooling or mounting specifications for large-frame units), while the drive itself utilizes Mitsubishi's flagship "Real Sensorless Vector Control." As a Brand New unit, it offers the sophisticated motor control, integrated safety (SIL3/PLe), and predictive maintenance capabilities required for heavy-duty industrial infrastructure, mining, and large-scale manufacturing.

Key Features

• Massive 400V Power Control: Engineered for large 3-phase 380-500V systems, providing consistent high-current output for the most demanding industrial motors.
• Real Sensorless Vector Control (RSVC): Delivers superior speed and torque accuracy, including 200% starting torque at 0.3Hz, ensuring stable control without an encoder.
• High-Level Safety Integration: Features built-in Dual-channel Safe Torque Off (STO) meeting SIL3 and PLe standards, eliminating the need for complex external safety circuits.
• Intelligent Maintenance: Equipped with life-diagnosis functions that monitor the health of main circuit capacitors and cooling fans, notifying users before failure occurs.
• Advanced PLC Functionality: Includes a built-in 6k-step PLC, allowing the drive to execute custom automation logic and manage complex I/O without an external controller.
• Energy Optimization: Uses Advanced Optimum Excitation Control to minimize energy consumption, even in heavy-duty applications, by optimizing motor flux based on real-time load.

Item Condition (Brand New)

• Functional Status: Brand New. Factory-fresh unit that has never been installed, wired, or energized.
• Physical State: Pristine. The high-current busbars, heavy-duty housing, and internal cooling architecture are in perfect, original condition.
• Packaging: Shipped in original Mitsubishi Electric industrial-grade packaging (often crated due to size) with all factory seals and documentation included.
• Visual Reference: Please refer to the high-resolution images to verify the specific nameplate ratings and configuration; the unit pictured is the exact high-capacity VFD you will receive.
