Specification

The MITSUBISHI MELSERVO-J4 Series Servo Amplifier 2KW MR-J4-200A represents the pinnacle of industrial servo drive technology, engineered for precision, efficiency, and scalability. This model delivers robust 2 kW rated output with a rated current of 11 A at 3-phase 170 V AC input, making it ideal for high-torque applications in automation lines, robotics, and CNC machinery. Its advanced sine-wave PWM control ensures minimal torque ripple and superior speed regulation, while the built-in dynamic brake guarantees safe stopping in emergencies. The amplifier’s interface power supply operates at 24 V DC ±10% with a current capacity of 0.5 A (including CN8 connector signals), and it supports both USB and RS-422/RS-485 communication for flexible integration into existing systems. For higher power models (e.g., 11KA, 15KA, 22KA), an external dynamic brake option is available. Below are the comprehensive specifications for the MR-J4-200A and related models.
