Mitsubishi HK-KT43G5-1-5 Regenerative Resistor Unit for MELSERVO J4 Series

The Mitsubishi HK-KT43G5-1-5 is a regenerative resistor converter unit designed for use with the MELSERVO J4 servo drive series. It provides controlled dissipation of regenerative energy produced during motor deceleration or braking, protecting the servo amplifier from overvoltage conditions and ensuring smooth, reliable operation of the drive system. This unit features a rated output of 500 W (0.5 kW) and a resistance value of 6.7 Ohm. It is compatible with AC supply voltages of 100 V or 200 V, allowing integration into a variety of machine configurations. The HK-KT43G5-1-5 is functionally equivalent to the Mitsubishi MR-RB51 regenerative braking resistor unit. It is suited for applications where servo-driven axes require frequent deceleration or positioning stops, such as CNC machinery, packaging equipment, and automated assembly systems using Mitsubishi MELSERVO J4 servo amplifiers.
