Mitsubishi Electric FR-A840-00470-2-60 FR-A800 Series Inverter

Description

Engineered for precise speed and torque regulation of three-phase AC motors, the FR-A840-00470-2-60 variable frequency drive represents the standard design configuration within the Mitsubishi Electric FR-A800 Series. Operating within the 400V voltage class, this inverter is configured as a standard CA-type model, optimized for reliable performance in demanding industrial environments. The unit features an integrated circuit board coating compliant with IEC 60721-3-3 Class 3C2 specifications to safeguard sensitive electronics against corrosive gases and moisture, while utilizing non-plated conductors to align with specific environmental and technical requirements.

With a Super Light Duty (SLD) rated current of 47 A, this drive provides efficient motor control for applications requiring high-capacity current output under variable loads. Its modular construction and robust cooling design ensure long-term operational stability in centralized control cabinets and heavy-duty machinery systems.

Features

• Standard CA-Type Architecture: Designed for seamless integration into global industrial power systems and control layouts.
• 3C2 Circuit Board Coating: Enhanced protection against aggressive chemical and environmental substances under IEC 60721-3-3 guidelines.
• Optimized Duty Rating: Delivers a Super Light Duty (SLD) rated inverter current of 47 A for fluid-handling and mechanical transmission tasks.
• Non-Plated Conductors: Specific structural configuration designed to meet mechanical longevity and connection standards without standard plating.

Applications

• Pumping stations and industrial wastewater treatment facilities.
• Ventilation systems, industrial blowers, and large-scale HVAC air handlers.
• Conveyor systems and material handling machinery.
• Compressor control and general factory automation processes.

Technical Specifications

Installation Guidelines

• Mounting Location: Install the inverter vertically on a flat, heat-resistant surface inside a control panel to ensure unrestricted airflow through the cooling heatsinks.
• Clearance Requirements: Maintain specified clearance distances at the top, bottom, and sides of the unit for optimal thermal dissipation.
• Grounding: Ensure a low-impedance safety ground (PE) connection is established to the designated grounding terminals before applying utility power.
• Environmental Protection: Although equipped with 3C2-rated board coatings, avoid direct exposure to moisture, conductive dust, and explosive gas mixtures.

Compliance and Certifications

• IEC 60721-3-3 Class 3C2 (Chemical and environmental resistance for circuit boards)
