Mitsubishi FR-HEL-1.5K DC Reactor for FREQROL Inverters

The Mitsubishi FR-HEL-1.5K (FR-HEL-1.5K) is a DC reactor designed for use with Mitsubishi Electric FREQROL series variable frequency drives. Engineered specifically for 1.5 kW inverter systems, this power factor improving direct current reactor suppresses harmonic currents generated by the drive rectifier, protects internal drive components, and significantly improves overall power efficiency. Integrating a dedicated DC reactor like the FR-HEL-1.5K between the inverter's converter and inverter sections reduces input AC line harmonics, decreases thermal stress on upstream power supply equipment, and enhances drive reliability across demanding industrial automation systems. This component is commonly deployed with FREQROL FR variable speed drives in automated machinery, conveyor systems, pump and fan controls, packaging equipment, and manufacturing plant installations where power quality standards and clean electrical distribution are critical. With its robust industrial construction, the unit connects directly to the drive DC link terminals to ensure stable operation and extended service life for both the motor controller and connected equipment.
