The Mitsubishi MR-J4-70B is classified as a servo amplifier intended for high-performance applications. This device operates on a main circuit voltage of 170-264 V AC, which can accept both single-phase and three-phase configurations. The amplifier maintains a rated current output of 5.8 A and requires a main circuit input current of 3.8 A.

The control circuit operates within a voltage range of 200 to 240 V AC and functions within a frequency range of 50/60 Hz. It reflects a low input current requirement of just 0.2 A, in combination with a control circuit consumption rating of 30 W, ensuring efficient operation. Notably, the control circuit voltage can also accept input from 170-264 V AC.

Additionally, the interface supply voltage integrates a specification of 24 V DC ±10%. The MR-J4-70B employs a sine-wave PWM control method to enhance performance fidelity. Included in the design is a built-in dynamic brake feature, which aids in providing high-speed deceleration and precise control during operation. The main circuit frequency tolerance is rated at ±5%, reflecting the device's capability to handle slight variations effectively.
