Eaton Specification Sheet - X48M28T2216CUNON
DOE 2016 efficiency and UL Listed safety define the core specification of this transformer. The energy-efficient design minimizes line losses, lowers operating heat, and reduces lifetime energy costs for facilities with nonlinear loads. It is ideal for floor-mounted installations in data centers and manufacturing lines where reliability and safety cannot be compromised. Selectable taps (+2.5% on two taps, and -2.5% on four taps) allow precise voltage tuning under varying load and input conditions. The result is steadier 208Y/120 V secondary output, reduced voltage stress on downstream equipment, and fewer nuisance trips during voltage sags. This is particularly valuable in multi‑supplier power environments and when feeding sensitive drives or PLCs. Three-phase 480 V primary to 208Y/120 V secondary with copper windings delivers robust electrical performance and high efficiency. The copper windings offer excellent thermal and electrical conductivity, enabling consistent voltage regulation and long service life. The FR944 frame and 200X wiring connection support straightforward mounting and connection to standard plant power rails. Rugged NEMA 2 enclosure and 60 Hz operation withstand typical indoor plant conditions. The 220 °C insulation and 150 °C rise ensure safe operation under peak loads, while floor mounting and the FR944 frame simplify site integration. Compliance and documentation streamline procurement and maintenance. DOE2016 efficient standard and UL Listing provide regulatory confidence, while catalog notes reference 10 CFR Part 431 (2016) Efficient. These factors support predictable ROI by reducing energy waste and extending equipment life in continuous-operation environments. Copper-wind coil transformers offer measurable gains in reliability when paired with modern harmonics mitigation strategies. For facilities expanding capacity or modernizing legacy systems, this model provides a straightforward upgrade path without rewiring, facilitating quick installations and consistent performance.
