Feature → Business Impact → Application. The K-Factor 13 nonlinear design mitigates harmonic distortion, reducing overheating and improving voltage regulation, which lowers energy losses and extends transformer life in harmonic-rich automation environments. This supports reliable operation on manufacturing floors and in drives-heavy facilities, enabling safer, more predictable power delivery to automated panels. DOE2016 Efficient compliance delivers measurable energy savings, decreasing operating costs and cooling loads in continuous-process plants and data centers. The UL Listed safety certification provides confidence for code-compliant installations, streamlining procurement, installation, and maintenance in industrial settings. The 75 kVA three-phase rating with 480 V input and 208Y/120 V output suits scalable panel boards and modular automation racks, while the FR942 frame offers robust cooling and straightforward mounting in constrained electrical rooms. K-Factor 13 capability and compact ventilated design reduce downtime and support long-term reliability in demanding environments.
