MR-J3-22KA4-LC078

The Mitsubishi MR-J3-22KA4-LC078 is an AC servo amplifier engineered to precisely control demanding motor applications. Designed for 3-phase input, this amplifier requires a voltage supply between 380 and 480 volts AC. It provides a remarkably rated output of 22 kilowatts, making it suitable for high-power machinery. This unit employs sine wave pulse width modulation (PWM) and current control methods to ensure smooth and efficient operation.

An external dynamic brake enhances braking capabilities, further improving performance efficiency. With a current rating of 63 Amperes, the amplifier operates effectively within its limits while drawing a typical input current of 47.6 Amperes. Cooling is achieved through a forced ventilation method, which is critical for maintaining optimal operational temperatures.

Regarding power consumption, this unit operates at just 45 Watts, enabling energy-efficient performance. The input frequency compatibility ranges from 50 to 60 Hertz, offering flexibility across different electrical systems. The amplifier utilizes a 24 Volts DC power supply with a capacity of 0.3 Amperes for the interface, optimizing its communication functionality. The RS-422 protocol facilitates the communication between devices. It's essential to note that the enclosure rating is IP00, indicating that it has an open design and is not protected against environmental factors.
