MR-J3-350B

|

Mitsubishi Electric created the MR-J3-350B, an AC motion servo drive/amplifier developed for applications requiring high control accuracy. This MELSERVO-J3 sequencing servo generates a 3.5kW rated output and a rated current of 17 amps, and it uses sine-wave PWM control and a current control type control mechanism. It has high output power, a wide input voltage range, and support for several communication protocols. It is also small and light, making it simple to install and use. Its operating ambient air temperature ranges from 0 to 55 degrees.
