Feature → Business Impact → Application: The K-Factor nonlinear ventilated design with aluminum windings and a 220 °C insulation class delivers improved thermal management and reduced copper loss, translating to lower operating temperatures and enhanced reliability in continuous-duty applications. This supports longer component life and measurable energy savings, especially in facilities with variable loading and frequent startup sequences such as packaging lines and CNC plants. Feature → Business Impact → Application: DOE 2016 efficiency compliance and 10 CFR Part 431 alignment ensure regulatory squarely met, reducing audit risk and potential incentive eligibility for energy programs while delivering lower total cost of ownership over time. Feature → Business Impact → Application: NEMA 2 enclosure and floor-mounting provide rugged protection in industrial environments, enabling straightforward installation in production floors, switchgear rooms, or maintenance bays without additional weatherproofing. Feature → Business Impact → Application: Voltage regulation options through 2 at +2.5%, 4 at -2.5% taps enhance voltage stability on sensitive loads, minimizing equipment misoperation and burnout in critical processes like plating lines or robotics cells. Feature → Business Impact → Application: A three-phase 480 V primary and 208Y/120 V secondary with 60 Hz frequency supports standard facility power distribution, promoting compatibility with existing upstream supplies and downstream equipment such as PLCs, drives, and motors in data centers, fabrication floors, and automation centers. Feature → Business Impact → Application: The 225 kVA rating, coupled with a compact FR945 frame and configurable taping, offers scalable distribution for mid-sized plants, enabling quick migration paths as facility loads grow while keeping installation footprint manageable.

FAQs

Yes. The transformer is specified for a 480 V primary, three-phase network and delivers a 208Y/120 V secondary. This makes it suitable for facilities that run 480 V feeders and require step-down distribution to common control and instrumentation voltages. When planning, verify downstream load balance and ensure proper tap settings to optimize voltage regulation at peak loads.
The N48M28F2216 adheres to DOE 2016 efficiency standards and 10 CFR Part 431 guidelines, reflecting energy-conscious performance. It uses aluminum windings with insulation rated to 220 °C, supporting reliable operation under typical industrial temperatures. A 115 °C rise rating helps anticipate cooling requirements during high-load conditions.
This transformer fits manufacturing, processing, automation, and data-center environments where three-phase power distribution and reliable voltage regulation are essential. With a 225 kVA rating and a NEMA 2 enclosure, it supports floor installations in harsh factory floors while meeting regulatory and energy-efficiency requirements common to industrial facilities.
Key certifications include UL Listed status for safety and DOE 2016 efficiency compliance for energy performance. The unit aligns with 10 CFR Part 431 (2016) Efficient guidelines and features a NEMA 2 enclosure for rugged environments. These certifications simplify procurement and regulatory reporting for industrial operators.
Expect lower energy-related costs due to DOE 2016 efficiency and robust cooling from the ventilated design. Maintenance benefits come from aluminum windings and a compact FR945 frame that support durable operation with fewer reactive components. Plan for periodic electrical testing, voltage tap verification, and enclosure integrity checks to maximize long-term ROI in mid-size facilities.
