Mitsubishi FR-HEL-H90K DC Reactor for FREQROL Inverters

The Mitsubishi FR-HEL-H90K (FR-HEL-H90K) is a DC reactor engineered for use with Mitsubishi FREQROL series variable frequency drives. Installed in the DC link circuit of compatible drive systems, this component functions to improve the overall input power factor, suppress harmonic currents, and protect internal inverter circuitry from power supply irregularities and transient electrical surges. It is commonly utilized across automated manufacturing facilities, processing plants, and motor control centers operating variable speed motor drives. Weighing approximately 10 kg, the reactor provides robust inductive filtering and smooths direct current ripple to promote steady drive operation and extend the service life of connected drive components. Integrating the FR-HEL-H90K into compatible FREQROL inverter installations helps ensure efficient operation in demanding continuous-duty applications while reducing harmonic interference across the facility power distribution network.
