K-Factor 13 nonlinear design reduces voltage distortion under non-linear loads, improving load regulation and extending transformer life in drives and rectifier-heavy systems. Copper windings deliver lower I2R losses and superior thermal performance, supporting aggressive duty cycles and a 150 °C rise rating for reliable operation in demanding environments. DOE 2016 Efficient and UL Listed certification ensure compliance and lower long-term energy expenses, helping facilities meet evolving regulatory requirements while reducing cooling needs. The NEMA 2 enclosure provides indoor protection against dust and moisture, enabling flexible floor or wall mounting for space-constrained plants. With a 208 V primary and 208Y/120 V secondary in a three-phase, 30 kVA package, this transformer aligns with common utility voltages and equipment, simplifying system integration. Tap options at +2.5% and -2.5% offer precise voltage regulation to compensate for loading and supply variation, reducing voltage-related equipment stress. The WS58 Weathershield option expands outdoor applicability, while electrostatic shield modification improves EMI performance and safety in sensitive installations. Collectively, these features translate to measurable ROI through improved reliability, reduced energy waste, and simplified maintenance in manufacturing floors and data-intensive facilities.
