K-Factor nonlinear design improves handling of harmonic loads, reducing overheating and extending equipment life. This translates to more stable voltage regulation for drives, controls, and sensitive electronics, lowering maintenance costs and downtime in manufacturing floors and data center rooms. The inclusion of 2 taps at +2.5% and 4 taps at -2.5% provides precise voltage adjustment to compensate for line drops and phase imbalance, ensuring consistent performance across fluctuating load conditions. With a 225 kVA three-phase rating, the transformer supports mid-to-large facilities, enabling scalable power distribution without oversizing or unnecessary capital expense. Aluminum coil construction minimizes copper loss and enhances thermal performance, while the ventilated design improves cooling in challenging electrical rooms. At 150 °C rise with 200 °C insulation, it maintains safe operation in hot environments, reducing the risk of thermal faulting. The compact footprint, combined with electrostatic shielding, helps meet space constraints and supports safer installations in restricted or retrofitted layouts. Compliance with NEMA TP-1 and UL listings, along with NEMA TP-1 efficient catalog notes, simplifies procurement, commissioning, and maintenance planning while delivering dependable long-term performance.
