MR-J3-100B4

Mitsubishi's MR-J3-100B4 AC servo amplifier is engineered for precision and reliability in demanding control applications. It provides continuous output power rated at 1 kW and operates effectively with an output voltage of 3-phase 323 VAC. Capable of handling output frequencies from 0 to 360 Hz, this amplifier is suitable for a broad spectrum of scenarios.

Power is supplied through a three-phase input of 380-480 VAC at 50/60 Hz, with a main circuit current rating of 2.5 A. It supports a supply range that allows for voltages between 323 and 528 VAC, providing flexibility in installation. The unit utilizes sine-wave PWM current control for optimal performance across various loads.

The interface supply operates at 24 V DC with a capacity of 0.2 A, facilitating straightforward system integration. The amplifier exhibits a rapid response time of 8 ms when the STO (Safe Torque Off) is disabled, enabling prompt reaction to control commands. Additionally, it incorporates a built-in brake transistor and resistor for effective braking and regenerative capabilities, enhancing system efficiency.

Cooling is achieved through natural air convection in an IP00 enclosure, which does not provide ingress protection. The operating temperature range for this unit is between 0 and 55 °C without condensing moisture, making it well-suited for various environments where temperature control is feasible. Overall, the MR-J3-100B4 is designed to fulfill the demands of advanced servo-driven applications, assuring reliable performance in a compact form.
