MR-J3-20T

The MR-J3-20T, designed by Mitsubishi, is an AC servo amplifier specifically employed for turret indexing applications. This unit is capable of operating at a supply voltage rating between 200 and 230 Volts AC, ensuring compatibility with various industrial power systems. The rated output voltage is specified at 170 Volts AC, which supports efficient motor control operations.

This particular amplifier employs a control methodology that integrates sine wave pulse width modulation (PWM) alongside current control techniques, enabling precise motion control throughout its operational parameters. The rated current is set at 1.5 Amperes, while the input current consumption mirrors this rating.

For cooling, the MR-J3-20T relies on natural cooling, eliminating the need for additional cooling equipment. It can function with either a 3-phase or 1-phase input phase type based on the installation requirements. Enhancing its utility, the unit incorporates a built-in dynamic brake to facilitate quick stops when necessary.

In terms of power metrics, it maintains a rated active power output of 200 Watts while drawing only 30 Watts during operation. Communication capabilities include compatibility with RS-422 and CC-Link protocols, making it suitable for integration into more extensive control systems. The amplifier is classified with an IP00 rating, indicating it has an open enclosure.

At a weight of 1.76 pounds (0.8 kilograms), the MR-J3-20T offers a lightweight option for various applications. This servo amplifier stands out as a functional and robust choice for precise turret indexing control in automation systems.
