Mitsubishi FR-HEL-H132K DC Reactor for FREQROL FR Inverters

The Mitsubishi FR-HEL-H132K (FR-HEL-H132K) is a DC reactor designed for use with Mitsubishi Electric FREQROL FR series variable frequency drives. Installed in the intermediate direct current circuit of the inverter system, this DC link choke functions primarily to suppress harmonics on the power supply side and significantly improve the input power factor of the drive. It helps reduce line distortion, minimizes electrical stress on upstream electrical distribution components, and protects the connected drive from supply side voltage transients and surges. The FR-HEL-H132K is configured for high-capacity FREQROL inverter applications, facilitating stable power conversion in demanding industrial environments. Operating within factory automation and motor control setups, this DC reactor is typically utilized alongside FREQROL drive installations powering large pumps, compressors, fans, extruders, material handling systems, and heavy industrial machinery. Integrating the Mitsubishi FR-HEL-H132K into the drive system enhances overall electrical reliability, supports smoother system operation, and extends the operational lifespan of the associated frequency inverter equipment.
