Product Details

  • Melservo MR-J2 Servo Amplifier 3.5kW (MRJ2S350B)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO MR-J2

Product Description

The Mitsubishi MR-J2S-350B (MRJ2S350B) is a Melservo MR-J2 series servo amplifier that generates 3.5kW of output wattage. This servo amplifier has a main circuit power supply that is 3 phase with a frequency that spans from 170VAC to 264VAC and a frequency of 50/60Hz. The circuit power supply’s rated current is 16.0A. The authorized voltage fluctuation has a gamut of 170 to 264VAC while the frequency can flux within -5% and +5%. The rated output for the MR-J2S-350B is also a 3-phased and generates 170VAC and has a corresponding rated current 17.0A.

The MR-J2S-350B servo amplifier has multiple ports in which allows for many different connections. The CN5 port permits a USB (MR-J3USBCBL3M ) cable connection. This connection sanctions personal computer communication with the servo amplifier and whatever appendage there is to this product. Another important connection is to the SSCNET III/H. This network can connect the MR-J2S-350B amplifier to other amplifiers and system controllers like the Q173DSCPU, the Q170MSCPU, etc. This connection can be made by a SSCNET cable to either the CN1A or CN1B port.

There are multitudes of servo or drive motors which the MR-J2S-350B servo amplifier. There are seven rotary servo motors, four linear servo motors, and three direct drive motors that can be concatenated to this amplifier. These servo motors can be connected to the MR-J2S-350B amplifier by two appending cables. The servo motor power cable can connect to a junction terminal block and the encoder cable is able to connect to the CN2 port that is directly below the junctional terminal.
