MR-J4-500A

The MR-J4-500A model, classified as a servo amplifier in Mitsubishi's MELSERVO MR-J4 lineup, is built for demanding automation environments. This unit provides a rated output voltage of 170 VAC and is configured to handle three-phase operations. With an output current capability of 28 Amps, the amplifier ensures precise and effective control of servomotors.

Powering this device requires a main circuit input voltage of 200 to 240 VAC, accommodating standard industrial power supplies running at 50 or 60 Hz. The current rating for the main circuit is set at 21.7 Amps, ensuring robust power delivery for heavy-duty applications. Control circuits within this model are powered through a 1-phase supply, also rated between 200 and 240 VAC, consuming a current of 0.3 Amps while requiring 45 Watts of power. Notably, there is an inrush current of 30 Amps at startup, which may be important for circuit protection considerations.

Additionally, the 24 VDC interface power supply simplifies integration with various control systems, facilitating communication between the amplifier and other components. The control approach utilizes sine-wave PWM alongside a current control method to achieve high efficiency and performance during operation.

This unit incorporates a built-in dynamic brake, enhancing safety and responsiveness during operation. It features an open structure with an IP20 rating, which, while offering basic protection from objects, requires installation in a controlled environment. For operational reliability, the MR-J4-500A is rated for ambient temperature conditions ranging from 0 to 55°C, ensuring it functions effectively across diverse industrial scenarios.
