MR-J4-350B

The MR-J4-350B is an AC servo amplifier designed for servo motor control applications. It was manufactured by Mitsubishi in the MELSERVO-J4 series, and it comes with an SSCNET III/H interface option. The MR-J4-350B servo amplifier has an STO (IEC/EN 61800-5-2) function that enhances system safety during operation. This servo amplifier also has several protective functions, including protective functions that can shut the system down to protect it from overvoltage errors, overcurrent errors, and servo motor overheating errors. The main circuit power supply input voltage requirements for the MR-J4-350B servo amplifier are 200 to 240 Volts AC of 3-phase power supply voltage with 50/60 Hertz of frequency and 170 to 264 Volts AC (3-phase) of permissible voltage fluctuation. This servo amplifier also operates with 200 to 240 Volts AC of 1-phase control circuit power supply voltage and a permissible control circuit power supply voltage fluctuation rating of 170 to 264 Volts AC (1-phase). The MR-J4-350B servo amplifier has a current control method and a sine-wave PWM control method. Additionally, the MR-J4-350B servo amplifier features a built-in dynamic brake for stable and efficient motor control. The servo amplifier's compact design is optimized for easy installation and to save installation space. The dimensions of the MR-J4-350B servo amplifier are 90 mm in width, 168 mm in height, and 195 mm in depth, and it weighs 2.3 kg, it is ideal for applications where installation space is limited. Furthermore, the MR-J4-350B servo amplifier complies with several international industrial standards, including the CE and UL standards. Its rated output voltage is 170 Volts AC (3-phase), and its rated output current is 17 Amps.
