Mitsubishi Electric FR-F840-00250-2-60 FR-F800 Energy-Saving Inverter

Description

Optimizing motor control in HVAC, ventilation, and pumping applications, the FR-F840-00250-2-60 frequency inverter belongs to the renowned Mitsubishi Electric FR-F800 series of energy-saving variable speed drives. This high-efficiency unit is specifically engineered to control variable torque loads, utilizing advanced excitation control algorithms to minimize energy consumption in industrial systems.

The FR-F840-00250-2-60 operates on a three-phase supply voltage ranging from 380 to 500 V AC. It features dual rating capability, allowing operators to choose between Super Light Duty (SLD) and Light Duty (LD) profiles based on thermal and overload requirements. Designed for seamless integration into modern industrial control architectures, it offers reliable speed control, robust protective mechanisms, and high durability under demanding ambient conditions.

Features

• Dual-rating operational profiles (Super Light Duty and Light Duty) for optimized motor sizing.
• Advanced energy-saving algorithms that dynamically adjust motor excitation according to the current load.
• High tolerance for line voltage fluctuations, accepting a wide input range from 323 to 550 V AC.
• Integrated PID controllers for direct pressure, flow, and temperature process control loops.
• Integrated cooling fan system with thermal management for high reliability.

Applications

• Centrifugal pumps and booster pump systems in municipal and industrial water treatment.
• Air handling units (AHUs), supply fans, and exhaust fans in commercial HVAC installations.
• Cooling towers, chillers, and secondary pump circulation loops.
• Industrial dust collection, exhaust systems, and blower applications.

Technical Specifications

Installation Guidelines

Ensure the inverter is mounted vertically on a flat, non-flammable surface to facilitate proper heat dissipation. Maintain a minimum clearance above, below, and to the sides of the drive as specified in the FR-F800 technical manual to prevent thermal choking. To minimize electromagnetic interference (EMI), utilize shielded cables for motor connections and ensure the drive chassis is securely grounded to the main system ground bus. Always isolate the input power supply before attempting any wiring modifications or terminal adjustments.
