Mitsubishi FR-HEL-H280K DC Reactor for FREQROL FR Series

The Mitsubishi FR-HEL-H280K (FR-HEL-H280K) is a DC reactor engineered for use with FREQROL FR series variable frequency drives and inverter systems. Designed to enhance system efficiency, this DC reactor connects into the direct current intermediate link of compatible drives to improve power factor and effectively suppress power supply harmonics generated during operation. By smoothing current ripple and attenuating electrical noise, the unit protects the drive input circuitry and extends the operating life of connected components. Built for heavy-duty industrial manufacturing environments, the FR-HEL-H280K supports high-capacity inverter installations across continuous process lines, manufacturing plants, and motor control centers. It is commonly implemented in demanding pump, fan, conveyor, and automated machinery drives where clean power and adherence to harmonic distortion standards are essential. Serving as a critical power-conditioning component, the Mitsubishi FR-HEL-H280K DC reactor ensures reliable operation, reduced thermal stress on upstream power equipment, and stable performance throughout demanding motor control applications.
