Product details

MR-J4-500B at a glance

The MR-J4-500B is Mitsubishi's 1-axis servo amplifier, delivering a main circuit rated current of 28 A and outputting 3-phase 170 VAC to drive servo motors. 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.
