The MR-J4-350B4-RJ amplifier by Mitsubishi is tailored for high-performance applications. It relies on absolute encoder feedback for precise positioning, achieving an accuracy of ±0.01 arc-min. The unit is designed to operate effectively within an ambient temperature range of 0°C to 55°C. In terms of safety, it includes functions such as Safe Torque Off (STO) and Safe Stop 1, enhancing system security.

With a rated output power of 3.5 kW and a current capacity of 16.0 A, the device delivers reliable performance for demanding industrial tasks. For power supply, it requires a 3-phase AC voltage within the range of 200 to 230 volts, with a tolerance of ±10%. The output voltage is consistently maintained at 200 V to 230 V.

Designed for efficient thermal management, it incorporates forced air cooling. The control capabilities of this amplifier facilitate vector control and position control. Communication is supported through RS-422/485 and SSCNET III ports, ensuring robust integration with other devices. The maximum speed achievable by the system may reach 3000 RPM, contingent upon the specific motor used.
