Mitsubishi MR-J4-15KA Servo Amplifier for MELSERVO-J4 Series

The Mitsubishi MR-J4-15KA (MR-J4-15KA) is an AC motion servo amplifier developed for the MELSERVO J4 series to deliver precise velocity, position, and torque control in demanding automated systems. This compact drive unit integrates dynamic braking functionality along with a built-in regenerative braking resistor, ensuring dependable energy dissipation and swift deceleration during machine cycling. Featuring multi-network interface compatibility including EtherCAT communication capability, the unit facilitates seamless integration into industrial network architectures. Operating on a 200 to 240 V AC supply voltage across 200 V class power systems, the amplifier accommodates both single-phase two-wire and three-phase three-wire electrical inputs. It is rated for an output of 100 W (0.1 kW) with a nominal current of 1.1 A, and it maintains reliable operation in ambient working temperatures ranging from 0 to +55 degrees Celsius. Built with an IP20 degree of protection, this servo drive is suitable for installation in protected electrical control cabinets. Equivalent to the MRJ410TMECT configuration, it is widely utilized across factory automation equipment, multi-axis machinery, packaging systems, and material handling lines requiring synchronized AC servo performance.
