FR-E740-3.7K Mitsubishi Variable Frequency Inverter 3AC 400V 18A 200-240 V

 

FR-E740-3.7K Description

 
The Mitsubishi FR-E740-3.7K is a high-performance, compact 3-phase variable frequency drive (VFD) from the FREQROL E700 series, designed for precise speed control of 3.7kW (5HP) induction motors. It integrates advanced sensorless vector control and V/F control technologies, delivering stable operation across a wide speed range with strong low-speed torque output. This inverter is engineered for industrial automation applications, offering reliable performance, rich control functions, and flexible communication capabilities, making it an ideal choice for various light-to-medium duty industrial equipment.
 

FR-E740-3.7K Features

 
  • High-Precision Torque & Speed Control: Adopts optimized sensorless vector control, delivering 150% rated torque at 0.5Hz for smooth heavy-load startup; supports a 1:400 wide speed regulation range (0.2–400Hz).
  • Strong Overload Capacity: Withstands 150% rated current for 60 seconds and 200% rated current for 3 seconds, ensuring stable operation under transient overloads.
  • Rich Built-in Functions: Integrates PID closed-loop control, multi-speed operation (15 steps), slip compensation, droop control, and automatic restart after instantaneous power failure.
  • Flexible Communication: Built-in RS-485 port supporting Modbus RTU protocol; compatible with optional Profibus communication modules for seamless system integration.
  • Compact & Space-Saving Design: Dimensions of 90mm (W) × 210mm (H) × 180mm (D), weighing ~3.5kg; supports side-by-side installation to save cabinet space.
  • Comprehensive Protection: Includes overcurrent, overvoltage, undervoltage, overheating, and short-circuit protection; features Safe Torque Off (STO) for enhanced operational safety.
  • User-Friendly Operation: Equipped with a 4-digit LED display and built-in operation panel; supports parameter setting via FR Configurator software through USB connection.
 

FR-E740-3.7K Materials & Applications

 

Materials

 
  • Housing: High-strength flame-retardant engineering plastic (UL94 V-0 rated) for excellent insulation and heat resistance.
  • Internal Components: High-quality IGBT modules, electrolytic capacitors, and heat sinks for reliable long-term operation; forced air cooling with a built-in fan for efficient heat dissipation.
  • Terminals: Nickel-plated copper terminals for good conductivity and corrosion resistance.
 

Applications

 
  • Pump & Fan Systems: Constant pressure water supply, exhaust fans, and air conditioning units (energy-saving operation via PID control).
  • Conveying Equipment: Belt conveyors, roller conveyors, and assembly lines (stable speed regulation and multi-speed switching).
  • Machine Tools: Small lathes, grinders, and drilling machines (high-precision speed control).
  • Food & Packaging Machinery: Mixers, filling machines, and packaging equipment (smooth operation and precise control).
  • Textile & Printing Machinery: Looms, dyeing machines, and printing presses (stable low-speed operation and tension control).
