The MR-J4-DU55KA4-RJ model from Mitsubishi's MELSERVO MR-J4 series serves as a high-capacity AC servo drive. It is designed to work within a wide supply voltage range of 380 Vac to 480 Vac. Operating with a significant rated current of 143 A, this device is capable of delivering a substantial active power output of 55 kW for various applications while maintaining a low power consumption of 45 W.

The control mechanism employed by this servo drive is based on sine wave PWM control, which facilitates smooth and efficient motor operation. Equipped with the SSCNETâ…¢/H command interface, the MR-J4-DU55KA4-RJ ensures fast communication between the drive and the controller. Additionally, the drive supports dynamic braking functionality, though this feature requires external options to be in place.

Protection features integrated within the design include safeguards against common risks such as overcurrent, overload, and undervoltage conditions, enhancing safety and operational integrity. Enclosed in an IP20-rated structure, this drive is suitable for environments where it will not be directly exposed to harsh conditions. Its operational range for ambient temperature is between 0 °C and 55 °C, making it adaptable for various industrial settings.
