The Mitsubishi MR-J2S-10B is a 100W AC servo amplifier engineered for high-precision motor control in industrial automation. Part of the MELSERVO-J2-Super series, this compact amplifier delivers sinusoidal PWM and current control with a speed frequency response exceeding 550 Hz. Real-time adaptive autotuning continuously optimizes control parameters, while active vibration suppression reduces mechanical noise. A built-in dynamic brake provides secure load holding.
Technical Specifications
Output power reaches 100W at 170 V and 1.1 A maximum output current. The amplifier accepts 3-phase 200–230 VAC or single-phase 230 VAC input (50/60 Hz) and accommodates supply voltage fluctuation from 170 to 253 VAC and frequency variation of ±5%. Output frequency ranges from 0 to 360 Hz. Control circuit power consumption is 50W, with input current between 0.9 and 1.3 A.
