Mitsubishi FR-E840-3.7K-1 Inverter is a high-performance, compact multi-purpose inverter belonging to the FR-E800 Series – an advanced product line from Mitsubishi Electric (Japan). The device stands out with precise control, energy-saving capabilities, support for various modern communication protocols, and stable operation in harsh industrial environments.
Specifications
- Capacity: 3.7kW
- Input Voltage: 3P 380V-480V 50/60Hz
- Output Voltage: 3P 380V-480V
Key Features
- Flexible Dual Ethernet Connectivity: Equipped with two Ethernet ports allowing connection in Line, Ring, or Star topologies without a Hub. High-speed CC-Link IE TSN network compatibility enables ultra-fast data synchronization between the inverter, PLC, and HMI.
- Advanced Vector Control Algorithms: Supports V/f control, advanced magnetic flux vector control, and real sensorless vector control. Helps the motor achieve maximum torque up to 200% even at ultra-low speeds (0.5 Hz).
- Built-in Mini PLC Function: Users can program basic control logic directly on the inverter via FR Configurator2 software without purchasing a separate PLC, significantly reducing hardware costs.
- International Safety Standards: Integrated STO (Safe Torque Off) safety function meeting SIL3/PLe standards, ensuring immediate motor power shutdown in emergencies without equipment damage.
- AI Fault Diagnosis and Predictive Maintenance: Monitors internal component degradation (capacitors, cooling fans, inrush current limit circuits) and provides early warnings.
Industrial Applications
With 3.7kW capacity and robust networking capabilities, it is optimal for automation systems:
- Conveyor systems & smart warehouses
- Mixing & centrifugal equipment
- Packaging & labeling machines
- HVAC pump & fan systems
Important Notes
- Control Panel Environment: IP20 protection degree requires protection against metal dust and high humidity. Maintain ambient temperature between -20C and +50C.
- Communication Wiring: Use industrial-grade shielded Ethernet cables (Cat5e STP or higher).
- Power Wiring: Connect 3-phase power to R/L1, S/L2, T/L3 terminals. Motor output goes to U, V, W terminals.
