Eaton Specification Sheet - N48M28B2216LS53
Feature → Business Impact → Application: The N48M28B2216LS53 uses K-Factor nonlinear design to optimize losses under varied load profiles, delivering lower energy costs across large controls and motor starter groups in manufacturing lines and processing facilities. This translates to measurable annual savings and compliance with energy-efficiency mandates, reducing total cost of ownership over the transformer’s life. Application wise, it supports critical loads in data centers, machine aisles, and automation panels where consistent voltage is essential. Feature → Business Impact → Application: Aluminum windings reduce material cost and thermal mass compared with copper alternatives, while maintaining durable performance for long runtimes. This improves procurement flexibility and long-term maintenance predictability in plant floors and service bays. The transformer’s weight and mounting footprint suit retrofit projects where space and handling considerations matter for quick installation.Feature → Business Impact → Application: DOE 2016 Efficient and UL Listed certifications provide risk mitigation for compliance audits and utility incentive programs. Facilities can leverage these credentials to meet corporate sustainability goals and qualify for energy rebates while ensuring reliable operation in harsh environments. Feature → Business Impact → Application: NEMA 2 enclosure and floor mounting deliver rugged indoor protection with quiet operation (53 dB), minimizing sound impacts in control rooms and adjacent workspaces. This enables closer equipment siting to loads and simplifies regulatory room layouts without sacrificing performance. Feature → Business Impact → Application: Voltage-tap options (+2.5%, -2.5%) allow precise voltage adjustment on three-phase 480 V primary systems feeding 208Y/120 V secondary circuits. This guarantees compatibility with multi-load configurations and reduces the need for additional intermediate transformers during plant expansion. Feature → Business Impact → Application: Electrostatic shield and 80 °C rise specification support robust electrical isolation and thermal management, improving reliability in high-humidity or dusty manufacturing environments and extending service intervals for mission-critical applications.
