FAQs
Install by connecting the primary to the 480 V supply and the secondary to 208Y/120 V loads using the 200X wiring configuration. Utilize the taps to adjust voltage: +2.5% and -2.5% as needed to maintain proper downstream voltages. Ensure proper enclosure, clearance, and adherence to UL and NEMA TP-1 guidelines during mounting and wiring.
The X48M28F15CUEETHR provides a -30° phase shift for harmonic impedance management. This offsets certain harmonic currents, reduces neutral current issues, and improves overall power quality for systems with non-linear loads such as drives and rectifiers, helping to protect downstream equipment and stabilize voltage.
Yes. It is designed for nonlinear loads common in data centers and manufacturing facilities. With UL Listed and NEMA TP-1 compliant markings, plus NEMA TP-1 efficiency notes, the unit delivers reliable power conditioning, reduces heat in cabinets, and supports lifecycle reliability for critical IT and automation infrastructure.
This transformer is UL Listed and NEMA TP-1 Compliant, with a NEMA TP-1 efficient rating noted in catalog. These certifications indicate compliance with safety, efficiency, and performance standards, reducing procurement risk, ensuring safer operation in industrial environments, and aligning with industry best practices for power distribution equipment.
Expect improved power quality with lower THD, reduced panel heating, and extended life for motors and drives due to stable voltages and controlled harmonic content. The copper wound construction and 15 kVA rating support efficient operation, while taps and phase shift enable flexible commissioning, contributing to lower maintenance costs and faster payback on new installations.
