Feature → Harmonic mitigating design with a dry-type distribution transformer and aluminum coils improves efficiency and reduces harmonic distortion. Business impact → Lower copper losses, decreased thermal stress on windings, and longer equipment life translate to lower maintenance and energy costs. Application → Particularly valuable in data centers, high-bay manufacturing lines, and solar PV installations where precise voltage and clean power are critical. Feature → Voltage regulation is achieved with taps at +2.5% and -2.5% to match system swings. Business impact → This reduces voltage flicker, protects sensitive equipment, and minimizes nuisance tripping. Application → Useful for campuses with varying feeder voltages or retrofit projects where exact voltage correction is needed. Feature → Primary 480 V with secondary 480Y/277 V and -30° phase shift supports standard Wye-Delta configurations. Business impact → Enables seamless integration with existing switchgear and neutral-based loads, improving fault protection coordination. Application → Common in industrial plants, data centers, and commercial facilities requiring consistent three-phase distribution. Feature → 75 kVA rating with 150 °C rise and 200 °C insulation enables robust performance in warm environments. Business impact → Higher short-term overload tolerance and reduced temperature-related derating translate to smaller footprints and lower total cost of ownership. Application → Suitable for harsh shop floors, outdoor enclosures, and retrofit projects where ambient temperatures vary. Feature → Electrostatically shielded construction and WS19 weather shield provide EMI protection and outdoor reliability. Business impact → Enhanced durability reduces downtime, supports compliance with outdoor standards, and extends service life. Application → Ideal for exterior installations and near high-EMI equipment. Feature → UL Listed and NEMA TP-1 compliant with a one-year warranty (or 18 months from shipment). Business impact → Simplifies procurement, accelerates approvals, and minimizes risk in regulated environments. Application → Fits industrial procurement across manufacturing, healthcare, and data center projects.
