Feature: The K-Factor nonlinear ventilated design minimizes harmonic currents and manages heat. Impact: Reducing harmonic stress protects downstream drives and relays, lowering maintenance costs and the risk of unexpected outages. Application: Ideal for automation panels and process lines with nonlinear loads in manufacturing facilities. Paragraph two highlights copper windings with shielded construction to improve efficiency and EMI/EMC performance, reducing stray losses and helping meet stringent plant electrical noise requirements. This feature proves valuable in dense panel assemblies and clean electrical rooms where space is at a premium. Paragraph three emphasizes DOE 2016 efficiency and 10 CFR Part 431 compliance, delivering predictable energy savings and regulatory alignment for facilities pursuing sustainability goals. Paragraph four covers the voltage regulation taps, +2.5% and -2.5%, which maintain output stability as loads shift—critical for CNC machines, robotics, and PLC-driven equipment. Paragraph five notes the rugged NEMA 2 enclosure, floor or wall mounting, and the 942 frame, which simplify installation, retrofit projects, and space planning in busy production floors. The optional electrostatic shield and WS59 weather shield (Weathershield) extend applicability to varied environments and EMI/EMC considerations, supporting long-term reliability in industrial power distribution.
