The MR-JE-300C is a single-axis digital AC servo amplifier rated for 3 kW continuous output, fed from a 200-240 VAC three-phase supply. That 3 kW figure is the mechanical shaft power it can deliver to a matched servo motor — not the electrical input draw, which will run higher due to drive losses and motor efficiency. For a 3 kW motor on a conveyor or positioning axis, this is the correct frame size; undersizing by one step risks nuisance overcurrent trips during acceleration.
