Inverters-FREQROL Multi-Functional Regenerative Converter

The FR-XC Series converter is a standalone addition to enhance the efficiency of general purpose Variable Frequency Drives (VFDs). It offers harmonic suppression and power regeneration in a single solution, using cutting-edge technology. This allows the FR-XC Series to bring significant cost reduction to systems such as those used in crane, roll-to-roll, and material handling applications.

• Dynamic braking regeneration – For power driving, the converter section of the VFD unit supplies power, and for regenerative driving, the FR-XC Series converter returns power to the power supply. (The FR-XC Series is not for use as a common converter while performing this function.) When the regenerative power is smaller than the VFD capacity, the more compact FR-XC power regeneration converter is the superior option.

• DC common bus regeneration – This function enables continuous regenerative operation at 100% torque. When the converter is connected to multiple inverters, regeneration energy from one inverter is shared among the others. Excessive energy is returned to the power supply, reducing energy consumption.

• Harmonic mitigation (18.5kW to 55kW) – Installing the FR-XC Series converter facilitates compliance with overseas standards related to harmonic suppression (5% or less).
