MR-J3-DU55KB4

The Mitsubishi MR-J3-DU55KB4 functions as a servo amplifier with high performance in control systems. It requires a control power supply that operates on a 1-phase voltage of 380 to 480 VAC, adhering to either a 50 Hz or 60 Hz frequency. With strict permissible voltage fluctuations of 323 to 528 VAC and frequency variations within ±5%, this unit ensures system stability.

The power consumption of the device is rated at 45 watts. It receives its main circuit power from the converter unit, integrating with the drive effectively. Offering an interface power supply of 24VDC, it has a capacity of 150 mA to support necessary interfaces and communication.

In terms of control mechanisms, this servo amplifier employs sine-wave PWM along with a current control system to provide precise control over connected servo motors. The design incorporates multiple protective functions, such as overcurrent and overload shut-offs, electronic thermal protection, and safeguards against servo motor overheating. Additional protections include encoder error detection, undervoltage, normal instantaneous power failure situations, overspeed conditions, and excessive error detection.

With a structure that features force-cooling and an open design, this model carries an IP00 rating, indicating that it should be installed in controlled environments free from moisture or dust exposure. Operating under a 400V voltage class, the inverse efficiency stands at 90%, ensuring effective energy use. The capacitor charging capacity is noted at 450 joules with a discharge time limit of 20 minutes, showcasing its readiness for immediate operation following charging.
