FR-BU2-H30K_Mitsubishi_PRODUCT_吉林易择科技技术发展有限公司

The FR-BU2-H30K is a braking unit designed for Mitsubishi FR series inverters, used to safely dissipate regenerative energy from motors during deceleration or load braking. It helps protect the inverter from overvoltage faults by directing excess energy to an external braking resistor.
