FAQs
For floor-mounted, indoor use in controlled spaces, ensure adequate ventilation and clearance around the enclosure, follow manufacturer mounting guidelines, and confirm alignment with DOE efficiency requirements. Verify that the installation area supports the 480 V primary and 208Y/120 V secondary configuration, and confirm any local electrical codes or UL requirements are met.
A 750 kVA transformer provides substantial headroom for peak loads and future expansion. Design considerations include voltage regulation under load, transformer impedance, and ensuring feeder capacity aligns with the 480 V to 208Y/120 V step-down. This enables reliable service for critical equipment while maintaining efficiency and manageable distribution losses.
Yes. With a 750 kVA rating, 480 V primary, and 208Y/120 V secondary, plus UL Listed and DOE 2016 Efficient compliance, it suits data centers, manufacturing lines, and process facilities requiring dependable, energy-efficient power distribution. The NEMA 1 enclosure and copper windings support durable indoor operation and long service life in harsh environments.
The N48D28B7716QCU is UL Listed and DOE 2016 Efficient compliant, with 10 CFR Part 431 notes. These certifications ensure safety, energy efficiency, and regulatory alignment for facilities pursuing energy targets and standard-based procurement.
Copper windings, 220 °C insulation, and a robust 80 °C rise design support durable performance and lower maintenance needs.
