Mitsubishi HK-KT43UWBKWS Regenerative Converter Unit for MELSERVO MR-J4 Series

The Mitsubishi HK-KT43UWBKWS is a regenerative converter unit designed for use with the MELSERVO MR-J4 series servo drive systems. It provides efficient energy recovery during motor deceleration by dissipating excess regenerative energy through its built-in resistor. The unit is rated at 850 W (0.85 kW) with a resistance value of 10 Ohm and operates on a 400 VAC supply voltage. It serves as an equivalent replacement for the MRRB6K4 regenerative unit. Regenerative converter units like the HK-KT43UWBKWS are essential in servo drive applications where frequent acceleration and deceleration cycles generate significant regenerative energy. By safely absorbing this energy, the unit protects the servo amplifier from overvoltage conditions and ensures stable system operation. The HK-KT43UWBKWS is suitable for integration into automated manufacturing lines, CNC machinery, and other motion control applications powered by Mitsubishi MELSERVO MR-J4 series servo amplifiers operating on a three-phase 400 VAC power supply. It is a reliable component for maintaining continuous and safe operation in demanding servo-driven environments.
