Feature: K-Factor 13 nonlinear design with copper windings and a FR942 frame delivers improved harmonic mitigation and thermal performance. Business Impact: lower copper losses and reduced ambient temperature rise translate to energy savings and longer transformer life in challenging installations. Application: ideal for industrial power distribution where non-linear loads—such as drives and rectifiers—are common, including manufacturing lines and data-center infrastructure. Feature: NEMA 2 enclosure with air-cooled, shielded construction provides rugged protection. Business Impact: UL Listed status and DOE 2016 Efficient rating support safer, compliant installations and easier procurement. Application: suitable for floor or wall mounting in electrical rooms, switchgear housings, and plant floors where space is constrained. Feature: Tap settings of 2 at +2.5% and 4 at -2.5% enable precise voltage regulation. Business Impact: reduces voltage stress on downstream equipment and improves system stability. Application: works with 380 V primary and 208Y/120 V secondary to accommodate modest supply variations across plant sites. Feature: 60 Hz performance with a 45 kVA three-phase configuration supports scalable power distribution. The design yields predictable capacity planning, reduces transformer count, and aligns with DOE 2016 efficiency targets. It suits medium-size industrial loads, data-processing racks, and control panel assemblies. In addition, copper windings and an electrostatic shield minimize stray losses and EMI, improving overall plant reliability. Feature: Copper windings, 150 °C rise insulation, 220 °C insulation rating, and 283M wiring connection. These specifications support continuous operation under peak loads and provide compatibility with standard cabinet interconnections. Feature: Weathershield WS59 enhances outdoor or dusty environments; electrostatic shield reduces EMI. Together they deliver robust protection for exposed installations, while maintaining performance in harsh conditions.
