K-Factor nonlinear ventilated transformer design minimizes harmonic distortion, delivering a cleaner power profile and reducing stress on downstream equipment. Business impact includes improved equipment life and reduced maintenance costs, particularly for motor drives and sensitive loads in manufacturing and data centers. Application: ideal for three-phase distribution with heavy harmonics where reliability and efficiency matter. Aluminum windings lower material costs while maintaining conductivity and thermal performance, contributing to lower operating temperatures and longer life in continuous-duty environments. Enclosure protection is provided by a rugged NEMA 2 housing, delivering resilience in dusty or damp indoor spaces and enabling straightforward installation on durable floors. Tap size options of +5% and -5% allow voltage fine-tuning to match site conditions, reducing voltage drop and optimizing performance. The electrostatic shield option supports EMI/RFI suppression, improving power quality for control systems and PLCs. WS61 weather shield compatibility adds outdoor or semi-exposed deployment versatility without compromising NEMA protection when configured for appropriate environments. This 112.5 kVA transformer runs at 60 Hz with a 208 V primary and 208Y/120 V secondary, delivering predictable performance for critical systems such as automated lines and process equipment.
