It accepts single- or three-phase 200–240 VAC at 50/60 Hz and includes a built-in dynamic brake, which means it can stop the motor quickly without an external braking resistor for most loads — a real space saver in a tight cabinet. Control is sine-wave PWM with current control, giving smooth torque at low speeds and decent efficiency across the speed range. The IP20 open-frame construction is natural convection cooled, so it expects to be mounted in a clean, ventilated enclosure — no washdown or dust here. The built-in dynamic brake and single/three-phase input flexibility make it a drop-in replacement for existing MR-JE-40A installations without rewiring the power stage. The 2.8 A rated current is the continuous output at the drive's rated load. That 400 W rating governs the motor frame size it can drive — typically a 400 W Mitsubishi HG-KN or HG-SN servo motor. The 200–240 VAC input range means it works on common global line voltages; just watch that single-phase input derates the available current slightly compared to three-phase. The built-in dynamic brake is a practical feature: it shunts motor regeneration into an internal resistor during a fast stop or E-stop, so you don't need to add an external braking unit for most point-to-point moves. For vertical loads or high-inertia applications, verify the stop time against the internal resistor's energy rating — but for typical rotary tables or conveyors, it's sufficient.","metaTitle":"Mitsubishi MR-JE-40A Servo Amplifier, 400W, 2.8A, IP20","metaDescription":"Mitsubishi MR-JE-40A servo amplifier, 400W, 2.8A rated current, 200-240VAC 1/3-phase, built-in dynamic brake, IP20, current production.
