The Mitsubishi SC-J2SJ4KT1K (SC-J2SJ4KT1K) is a servo amplifier renewal kit for converting MELSERVO MR-J2S-A installations to the MR-J4-A series. It is intended for MR-J4-A-RJ servo amplifiers with 700 W and 1 kW capacities and supports individual replacement as well as collective replacement work during a drive renewal. The kit carries Mitsubishi material number 271193 and is classified as standard material with logistic class C. The kit measures approximately 70 mm in width, 168 mm in height, and 190 mm in depth, and it weighs about 1.6 kg. It is used in maintenance and modernization projects where existing MR-J2S-A drives are replaced by MR-J4-A units, helping keep MELSERVO-based machinery in service. The renewal kit is suitable for production equipment that uses these servo drive series and requires the matched kit for the 700 W to 1 kW amplifier range.
