The Mitsubishi MR-J4-DU37KB4-RJ is designed as a robust servo drive, accommodating a voltage range of 380V through 480V and a capacity rated at 37 kW. Communication with this unit occurs through the SSCNETâ…¢/H command interface, which delivers superior connectivity for control applications.

With a rated current of 53 A, the MR-J4-DU37KB4-RJ is engineered to utilize three-phase power input efficiently. It requires a primary circuit power input of AC380V-480V. Besides, the control circuit is powered via a single-phase input of 200V to 240V at a frequency of 50/60 Hz, drawing a minimal current of 0.3 A.

This drive can tolerate voltage fluctuations of up to ±10% and frequency variations of ±5%. Additionally, the drive’s encoder emits incremental ABZ phase pulses for precise feedback on position and speed. External dynamic brake options can be integrated as needed for added functionality.

The built-in safety features protect against overcurrent, overload, and undervoltage conditions, ensuring reliable operation. Its construction conforms to an IP20 protection class, indicating adequate protection against solid objects while not water-resistant. This drive is a solid choice for demanding industrial motion control tasks.
