The Mitsubishi MR-J3-DU37KB4 is a well-constructed servo amplifier equipped to handle demanding applications. Weighing 18 kg, it is tailored for efficient operation within the MELSERVO MR-J3 series. This unit has an output-rated voltage of 3-phase 323VAC and delivers an output current of 102A, making it suitable for high-performance requirements.

The drive's converter unit supplies the power necessary for the main circuit. The control power supply effectively operates between 1-phase 380 to 480VAC with a frequency of 50/60Hz and maintains a rated current of 0.2A. This model is flexible, as it can handle permissible voltage fluctuations ranging from 323 to 528VAC. Frequency fluctuations are acceptable within a deviation of +/-5%.

With a total power consumption of 45W, the amplifier integrates an interface power supply of 24VDC ±10% with a current capacity requirement of 0.3A. It employs a control system based on sine-wave PWM and current control, ensuring precise motor performance. The amplifier's structure is designated as IP00, which indicates fan cooling in an open design, suitable for environments with controlled conditions.
