Omron's CIMR-E7C4018 is a robust 400 V class inverter that effectively serves industrial applications. This inverter supports a maximum motor output of 18.5 kilowatts and has a rated output capacity of 30 kilovolt-amperes. The rated output current stands at 39 amperes, ensuring compatibility with various motors.

The inverter is designed to deliver a maximum output voltage of 380 to 480 volts AC, matching the input specifications. It can handle output frequencies up to 120 hertz, suitable for dynamic applications requiring variable speed control. Users can choose between rated frequencies of 50 or 60 hertz based on their specific needs.

Voltage fluctuation capabilities range from 10% to -15%, while frequency fluctuations are manageable within ±5%. Optional components include a DC reactor, enhancing flexibility for specific applications. However, this unit does not support 12-phase rectification.

The CIMR-E7C4018 employs a V/f control method, which regulates the voltage-to-frequency ratio to maintain optimal motor performance. For overload conditions, it can sustain 150% of its rated capacity for up to 60 seconds, offering robustness during peak loads. The inverter utilizes air cooling combined with forced ventilation to ensure effective heat management, promoting reliable operation in demanding environments.
