FR-E520-2.2K MITSUBISHI Variable Frequency Inverter 0.5kW To 500kW 0-400Hz 380V

1. Compact and Space-Saving Design:​ The slim, low-profile design allows for high-density mounting, significantly saving panel space and simplifying installation.
2. Easy Setup and Operation:​ Features a straightforward keypad with basic parameter settings and a simple frequency setting dial, enabling quick commissioning without complex programming.
3. Enhanced Energy Saving:​ Built-in energy-saving algorithm automatically optimizes voltage according to the motor load, reducing power consumption in light-load conditions (ideal for fan and pump applications).
4. Robust Protection Functions:​ Includes comprehensive protection features such as electronic thermal overload protection for the motor, overcurrent protection, and undervoltage protection to ensure system safety and longevity.
5. Flexible Control Options:​ Provides multiple control inputs including analog voltage (0-5V/0-10V), analog current (4-20mA), and multi-step speed selection via digital inputs.
6. Durable Construction:​ Designed with a high-strength resin case and conformal coating on the PCB to withstand dust, moisture, and corrosive gases in typical industrial environments.

• Enclosure:​ High-impact resistant, flame-retardant resin (UL94V-0) with a cooling fin design.
• Internal Components:​ PCB with protective conformal coating, aluminum heat sink, and long-life electrolytic capacitors.
• Cooling:​ Natural convection cooling (fanless) for quiet operation and reduced maintenance.
• Terminals:​ Screw-clamp terminals for secure power and control wiring.
• Applications:​ Ideal for variable speed control of fans, centrifugal pumps, conveyors, mixers, packaging machines, ventilation systems, and other general-purpose machinery using 3-phase induction motors.
