Variateur de fréquence série FR-F800 FR-F840-00770-2-60 de Mitsubishi Electric

Description

Designed for optimized motor control in pump, fan, and industrial HVAC applications, the FR-F840-00770-2-60 variable frequency drive delivers advanced energy-saving capabilities and precise velocity regulation. This Mitsubishi Electric high-performance inverter operates on a three-phase AC input supply, outputting a rated current of 77 A to drive high-inertia industrial loads efficiently.

The system features integrated cooling and filtration components designed to maintain operational stability within standard electrical panels. By utilizing intelligent optimum excitation control, the unit continuously adjusts the excitation current to match the motor load, minimizing energy consumption while maintaining peak torque delivery during variable torque operations.

Features

• Three-phase input configuration optimized for standard 380V to 500V AC power grids.
• Optimum excitation control algorithm for maximum energy efficiency in fan and pump systems.
• Integrated EMC filter to mitigate electromagnetic interference in sensitive industrial environments.
• Built-in forced air cooling system to maintain safe thermal thresholds during continuous high-load operations.
• IP00 open chassis protective rating designed for secure integration into customized control enclosures.

Applications

• Industrial heating, ventilation, and air conditioning (HVAC) systems.
• Water treatment facilities and municipal pump networks.
• Cooling tower fan speed regulation.
• Air handling units and exhaust extraction blowers.

Technical Specifications

Installation Guidelines

• Mount the inverter vertically on a flat, non-combustible surface to facilitate proper airflow through the forced air cooling channels.
• Ensure the protective earth (PE) terminal is connected directly to a dedicated low-impedance grounding point.
• Maintain the manufacturer's recommended clearance distances at the top, bottom, and sides of the unit to prevent thermal recirculation inside the enclosure.
• Select branch circuit protection and conductor sizing that correspond to the rated input current in accordance with local electrical codes.
