Mitsubishi MR-J4W03PWCBL30M-H Servo Drive for MELSERVO MR-J4

The Mitsubishi MR-J4W03PWCBL30M-H (MR-J4W03PWCBL30M-H) is an AC motion servo drive and amplifier designed for the MELSERVO MR-J4 series. Engineered for high-precision motion control applications, this unit provides motion regulation and reliable motor control across automated industrial machinery and production systems. It features SSCNET III/H communication capability for high-speed, synchronized optical network operation and offers compatibility with external safety units to support machine safety integration. This drive operates with an input supply voltage of 200 to 240 V AC (200 V class, 220/230 V AC) or 283 to 340 V DC, accommodating single-phase two-pole, three-phase three-pole, or direct-current power inputs. It delivers a rated output of 5,000 W (5 kW) with a rated operating current of 28 A. Key internal hardware includes an integrated dynamic brake and a built-in regenerative braking resistor to manage kinetic energy dissipation during deceleration. Built with an IP20 degree of protection, the servo amplifier is rated for reliable performance within ambient operating temperatures ranging from 0 to +55 degrees Celsius. This unit is also designated as equivalent to MRJ4500BRJJ001.
