FAQs
The transformer is designed for three-phase 480 V input and 208Y/120 V secondary distribution. Ensure adequate clearance for ventilation, confirm UL Listed compliance for wiring methods, and verify cabinet or pad mounting that matches the 31.5 in length, 34.5 in width, and 51 in height footprint.factory-specific layout should account for 1200 lb weight and required ambient conditions per DOE2016 efficiency guidelines.
K-Factor nonlinear design helps mitigate harmonics and improves fault tolerance in power feeds to sensitive equipment. This translates to reduced thermal stress on components, lower maintenance intervals, and greater uptime for automated lines and robotic cells, especially in facilities with dense electrical loads.
Yes, the N48D28F4921 is UL Listed and DOE2016 Efficient compliant. UL listing confirms safety and compatibility with industry installation standards, while DOE2016 compliance signals superior energy efficiency. Together, they reduce regulatory risk, simplify procurement criteria, and support green building or efficiency-focused programs.
Applications include data centers, manufacturing floors, and automation control rooms requiring stable voltage conversion from 480 V to 208Y/120 V. The 150 kVA rating supports scalable load growth, while its ventilated design manages heat effectively in space-constrained environments, enabling reliable operation of critical equipment.
Expect lower cooling costs due to DOE2016 efficiency and improved uptime from UL-listed safety standards. Routine checks should focus on ventilation, wiring connections (305K), and monitoring for temperature rise near 115 °C. Over time, energy savings and reduced downtime contribute to a favorable total cost of ownership, particularly in high-utilization facilities.
