Mitsubishi FR-HEL-2.2K DC Reactor for FREQROL Inverters

The Mitsubishi FR-HEL-2.2K (FR-HEL-2.2K) is a DC reactor designed for use with Mitsubishi FREQROL series variable frequency drives. Installed in the direct current link circuit of compatible FR inverter drives rated for 2.2 kW motors, this choke suppresses power line harmonics, reduces peak ripple currents, and significantly improves the overall input power factor. By smoothing the DC bus current, the reactor also reduces electrical stress on the inverter input rectifier stage and internal smoothing capacitors, extending the operating lifespan of the drive system. Engineered for seamless integration into industrial control panels and drive cabinets, the FR-HEL-2.2K provides robust protection against line voltage fluctuations and power supply transients. It is typically deployed across factory automation environments, including material handling lines, pump and fan controls, packaging machinery, and machining equipment operating with Mitsubishi FREQROL inverters. Integrating this component ensures stable electrical operation and compliance with plant harmonic distortion standards.
