Mitsubishi Electric FR-A720-18.5K Inverter

Description

Engineered for highly precise motor speed and torque regulation, the FR-A720-18.5K variable frequency drive (VFD) delivers robust control performance across demanding industrial environments. This three-phase power inverter module features advanced vector control technology, making it well-suited for heavy-duty machinery, material handling systems, and fluid control operations. As a legacy component of the Mitsubishi Electric automation ecosystem, this unit has been officially succeeded by the FR-A820-18.5K inverter, yet it remains a critical spare part for plants requiring direct mechanical and electrical interchangeability without system redesign.

Features

• High-torque performance across the entire speed range with integrated vector control capabilities.
• Efficient forced air cooling design to maintain optimal thermal conditions inside control panels.
• Rugged construction and components designed to endure continuous industrial service.
• Direct compatibility with standard legacy factory automation networks and motor setups.

Applications

• Heavy industrial machinery and process control lines
• Water and wastewater pump stations
• Factory conveyor systems and automated material handling
• Legacy machine retrofits and industrial plant maintenance

Installation Guidelines

• Mounting: Install the inverter vertically on a flat, non-flammable vertical surface to ensure efficient natural upward air circulation.
• Clearance: Maintain the manufacturer-recommended clearances on all sides of the housing to prevent thermal buildup within the enclosure.
• Grounding: Ensure the drive is securely connected to the plant ground system to protect personnel and reduce electromagnetic noise.
• Wiring: Route control signal cables and high-power motor cables through separate conduits to prevent cross-talk and signal distortion.
