Mitsubishi FR-HEL-H315K DC Reactor for FREQROL FR Inverters

The Mitsubishi FR-HEL-H315K (FR-HEL-H315K) is a high-capacity DC reactor designed for integration with Mitsubishi Electric FREQROL FR series variable frequency drives. Engineered specifically for demanding industrial drive installations, this DC link choke connects between the rectifier and inverter stages to suppress harmonic currents, reduce electrical noise, and improve the overall input power factor. By mitigating current ripple and smoothing the direct current supply, the unit helps protect the internal converter components against line surges and prolongs the service life of connected motor control equipment. This DC reactor is utilized in heavy-duty industrial automation applications, including manufacturing lines, material handling systems, pumps, fans, and process automation machinery powered by FREQROL FR series inverter drives. It serves as a vital component during routine maintenance, system upgrades, or drive repairs to ensure stable operation and compliance with plant power quality standards. The unit integrates seamlessly into industrial control cabinets and drive panels alongside compatible Mitsubishi motor controllers.
