Mitsubishi FFR-HEL-H30K-E1 DC Reactor for FREQROL Inverters

The Mitsubishi FFR-HEL-H30K-E1 (FFR-HEL-H30K-E1) is a high-performance DC reactor designed for use with Mitsubishi FREQROL series variable frequency drives. Engineered for 400 V class inverter installations rated at 30 kW, this DC link choke connects between the internal rectifier and inverter stages to suppress harmonic currents on the power distribution network and significantly improve the input power factor. By attenuating harmonic distortion and smoothing current ripple in the DC intermediate circuit, the unit protects drive electronics, extends the operational life of DC bus capacitors, and enhances overall power supply stability. This reactor is engineered for industrial motor control environments, including manufacturing lines, pump and fan systems, conveyors, and automated machinery powered by FREQROL frequency inverters. Its robust terminal construction ensures dependable electrical connectivity and heat dissipation under demanding continuous-duty industrial conditions. The component is essential for installations requiring compliance with harmonic mitigation standards and power quality regulations. Integrating the FFR-HEL-H30K-E1 into drive panels reduces system heat losses, minimizes electromagnetic interference, and supports the efficient and reliable performance of high-power Mitsubishi drive architectures.
