Rex Power Magnetics - Drive Isolation Transformers Rex Power Magnetics Drive Isolation Transformers are engineered to provide electrical isolation, harmonic mitigation, and transient protection for variable frequency drive (VFD) applications. These transformers supply clean and balanced power to the drive while protecting both upstream and downstream equipment from voltage disturbances, system transients, and harmonic distortion.

Rex Power Magnetics: How to Size and Select a Transformer Transformer design is a foundational step in building reliable electrical power systems. Choosing the correct transformer size and configuration directly influences system performance, efficiency, safety, and long-term operating cost. While it may be tempting to focus only on voltage ratings and kVA, proper transformer design requires a broader understanding of how the transformer will be used, where it will be instal
