Mitsubishi FFR-HEL-H7.5K-E DC Reactor for FREQROL FR Series

The Mitsubishi FFR-HEL-H7.5K-E is a DC link reactor engineered for use with Mitsubishi FREQROL FR series variable frequency drives and inverter systems. Designed to improve the overall power factor of the drive system, this DC reactor connects into the direct current intermediate link of compatible FREQROL inverters rated for 7.5 kW in 400 V class installations. By attenuating harmonic distortion and smoothing current ripple between the rectifier and inverter stages, the unit reduces stress on electrical distribution networks and protects upstream equipment from excessive electromagnetic interference. Installed in industrial control cabinets alongside FREQROL FR drives, the FFR-HEL-H7.5K-E operates in continuous motor control and automation environments. Typical industrial applications include pump stations, ventilation fans, material handling conveyors, machine tools, and process automation lines where power quality and equipment longevity are critical. The robust construction and dedicated terminal layout facilitate straightforward wiring into the inverter power circuit, ensuring dependable operational stability across varied manufacturing and industrial automation installations.
