Mitsubishi FR‑A820‑0.4K‑1‑60CRN Brand New FR‑A800‑CRN VFD

Product Overview

The Mitsubishi FR‑A820‑0.4K‑1‑60CRN is a Brand New, high-performance Variable Frequency Drive (VFD) from the specialized FR-A800-CRN series. As the most compact entry in the CRN lineup, this 200V class inverter is precision-engineered for small-scale Crane and Hoist applications. Despite its 0.4kW power rating, it is equipped with the same sophisticated crane firmware as the larger models, featuring advanced anti-sway control, mechanical brake sequencing, and high-torque performance. This Brand New unit is the premier choice for localized lifting tasks, high-precision positioning, and small material handling systems where safety and torque stability are paramount.

Key Features

• Crane-Dedicated Firmware (-CRN): Features specialized algorithms for mechanical brake sequence control, anti-sway logic, and automatic speed optimization based on load weight.
• Exceptional Starting Torque: Delivers 200% torque even at ultra-low speeds (0.3Hz) using Real Sensorless Vector Control, providing the necessary power to lift loads without roll-back.
• Integrated Anti-Sway Control: Automatically suppresses load swinging during trolley or bridge movement, significantly improving operator safety and reducing cycle times.
• Highest Safety Standards: Built-in Dual-channel Safe Torque Off (STO) meets SIL3 and PLe standards, ensuring the highest level of protection for lifting machinery.
• Precision Brake Logic: Dedicated parameters ensure seamless coordination between the drive’s torque delivery and the mechanical brake’s operation, reducing mechanical wear.
• Built-in PLC Functionality: Features a 6k-step PLC as standard, allowing for complex localized control of limit switches and hoist sensors without an external controller.

Item Condition (Brand New)

• Functional Status: Brand New. Factory-fresh unit that has never been mounted, wired, or energized.
• Physical State: Pristine condition. The compact chassis, terminal blocks, and internal cooling components are in perfect, original condition.
• Packaging: Shipped in the original Mitsubishi Electric factory box with all factory seals, internal protective materials, and crane-specific documentation.
• Visual Reference: Please refer to the high-resolution images to verify the specific CRN designation on the nameplate; the unit pictured is the exact VFD you will receive.
