Mitsubishi FR-XC-H37K Regenerative Converter for FREQROL FR Series

The Mitsubishi FR-XC-H37K (FR-XC-H37K) is a power regeneration common converter designed for use with Mitsubishi Electric FREQROL FR series variable frequency drives. This converter functions as a shared energy recovery unit, returning regenerative braking energy produced during motor deceleration back to the electrical power supply rather than dissipating it as waste heat through external braking resistors. By efficiently feeding surplus energy into the power line, the unit significantly enhances system energy efficiency, lowers operating expenses, and minimizes heat dissipation within electrical control enclosures. Engineered for seamless integration within common DC bus architectures, the FR-XC-H37K coordinates with multiple FREQROL drive units in continuous and cyclic duty cycles. The converter is widely deployed in high-inertia machinery and heavy-duty industrial equipment requiring frequent deceleration and rapid braking, including cranes, hoists, elevators, centrifuges, tension-controlled winders, and automated conveyor systems. Operating within the FREQROL ecosystem, this regeneration module delivers dependable thermal management, reduces power consumption, and maintains stable operational performance across demanding manufacturing facilities.
