Mitsubishi FR-HEL-15K DC Reactor for FREQROL Inverters

The Mitsubishi FR-HEL-15K (FR-HEL-15K) is a high-performance DC reactor engineered for use with Mitsubishi Electric FREQROL FR series variable frequency drives and inverters. Operating within the DC link circuit of compatible drive units, this power factor improving reactor suppresses harmonic currents and helps minimize power supply line distortion caused by inverter operation. By reducing harmonic distortion, it prevents nuisance tripping and improves overall energy efficiency and power factor across industrial power distribution networks. The FR-HEL-15K DC choke is matched to 15 kW inverter configurations in the FREQROL drive family. It connects directly to the drive DC bus terminals, offering vital electrical protection and system stabilization in motor control centers, pump and fan installations, conveyor systems, and automated production machinery. Engineered for dependable continuous operation in harsh industrial environments, this genuine Mitsubishi drive accessory ensures stable performance and compliance with power quality standards.
