Feature → Business Impact → Application: The N48M28F2216CSCU uses K-Factor nonlinear ventilation to improve cooling under harmonic-rich loads, reducing transformer temperature rise and extending service life. This translates to lower maintenance intervals and reduced risk of thermal derating in continuous processing environments such as metal fabrication or packaging lines. Application: Use in facilities with heavy drive systems and non-linear loads to maintain voltage integrity and minimize downtime. Feature → Copper windings and copper electrostatic shield reduce I2R losses and EMI, delivering improved efficiency and cleaner power for sensitive automation equipment. Application: Ideal for control cabinets and PLC-driven lines where EMI suppression protects measurement accuracy and control reliability. Feature → Enclosure NEMA 2 and floor mounting with a 945 frame provide rugged indoor installation, enabling quick deployment on shop floors while resisting dust and moisture ingress. Application: Suitable for industrial environments requiring durable, plug-and-play integration with existing floor space. Feature → DOE 2016 Efficient and 10 CFR Part 431 compliance ensures regulatory alignment and energy savings, lowering operating costs over the life of the asset. Application: Best fit for facilities pursuing energy-performance targets and compliance-driven procurement. Feature → Tap size of 2 at +2.5% and 4 at -2.5% enables precise voltage regulation, protecting downstream equipment and reducing voltage-related wear. Application: Critical where downstream motors and controls demand stable voltage under fluctuating loads. Feature → Copper shield and WS62 weathershield enhancement improve EMI containment and environmental protection, supporting safer operation in open-plan plant spaces. Application: Essential for high-density automation lines and areas with nearby radio/EMI-sensitive devices.
