The FR-XC Series offers a regenerative alternative to dynamic brakingMitsubishi Electric Automation, Inc. announces the release of the FR-XC Series Multi-functional Regenerative Converter, offering considerable energy savings and system cost reductions as supplemental hardware for Mitsubishi Electric´s FR Series of Variable Frequency Drives (VFDs). Geared towards end users in crane and material handling applications, the regenerated energy from one VFD in a lift application is used by another VFD to drive other motors in the system.


The energy saving effect presented by the FR-XC Series results in less wiring, smaller enclosures, reduction in power supply capacity, and reduction in facility size by power factor improvements. Used as a replacement to the network of transistors and resistors used in dynamic braking, the FR-XC Series can be used in three different modes of regeneration: dynamic braking regeneration, DC common bus regeneration, and harmonic mitigation (in DC common bus mode only). These modes can be further combined with the FR-XCL, FR-XCB or FR-HAL Series stand-alone reactors, and have different restrictions and applications.
