Control is sinusoidal wave PWM, yielding smooth torque at low speeds. Power consumption runs 45 W during operation. The main circuit accepts 3-phase 200–240 VAC 50/60 Hz; a single-phase AC200–240 V supply is also permitted for the control circuit via a 24 VDC interface drawing 0.3 A. Lead time typically runs 1–10 working days.","metaTitle":"Mitsubishi MR-J4-500B 1-Axis Servo Amplifier, 28 A","metaDescription":"Mitsubishi MR-J4-500B 1-Axis Servo Amplifier, rated 28 A main circuit, 45 W power consumption, sinusoidal PWM control.
