DOE2016 Efficient compliance is built into the N48M28F1221SR, delivering measurable energy savings in continuous industrial service. This translates to lower utility bills and reduced cooling demand in plant spaces, supporting a smaller energy footprint across automation lines. In manufacturing and data-center environments, these efficiency gains improve overall uptime and lower total cost of ownership without sacrificing performance. K13 XFMR K-Factor nonlinear ventilated design handles harmonics from variable-frequency drives and other nonlinear loads. The business impact is steadier voltages, reduced thermal stress, and longer transformer life. This capability is particularly valuable in facilities with variable-speed drives, robotics, and control panels where demanding loads fluctuate. 112.5 kVA three-phase rating supports mid-to-large automation loads while allowing simpler distribution planning. The business impact is fewer transformers to manage and improved load balancing, which boosts overall system reliability. Applications span manufacturing floors, packaging lines, and power-critical automation zones. 480 V primary to 208Y/120 V secondary compatibility supports common plant distribution schemes. The business impact is streamlined panel wiring, faster installation, and fewer custom interfaces. Applications include machine infeed sections and control panels requiring standard industry voltages. Ventilated frame with 115 °C rise provides effective cooling in dense enclosures. The business impact is lower thermal stack, extended service intervals, and better protection for connected equipment. Applications are in switchgear cabinets and power distribution units within harsh industrial environments. Robust dimensions and standard wiring connection 283B, frame 943, and a 31.5 in × 34.5 in × 51 in footprint with 1200 lb weight simplify mounting and retrofit projects. The business impact is predictable installation costs and compatibility with existing racks and supports. Applications include data centers, automotive plants, and process facilities where space planning matters. UL Listed certification and DOE2016 efficiency compliance provide safety and regulatory alignment. The business impact is reduced risk, faster approvals, and long-term operating savings across general power management and distribution tasks in industrial settings.
