FAQs
The N48M47B49EE is a three-phase transformer rated for 480 V primary and 480Y/277 V secondary, designed for standard rack or pad-mounted installations. Ensure adequate space for ventilation, maintain clearance around the enclosure, and verify tap settings (+2.5% and -2.5%) are configured per site voltage conditions. Mounting hardware and enclosure compatibility should align with manufacturer guidelines to minimize heat buildup and simplify conduit routing.
Key specs include a 150 kVA three-phase rating, 60 Hz frequency, 480 V primary, 480Y/277 V secondary, and dual tap options at +2.5% and -2.5%. The windings are aluminum with an 80°C rise rating, and the unit is electrostatically shielded to reduce EMI. It is NEMA TP-1 compliant and UL Listed, ensuring compliance with typical industrial power distribution standards.
Yes. The 150 kVA rating, 480 V to 480Y/277 V output, and K-Factor nonlinear ventilated design make it robust for data centers and manufacturing lines with nonlinear loads and variable-speed drives. The adjustable taps support voltage stability, while the shielding and compliance features help meet EMI requirements and code standards, reducing risk during audits and commissioning.
The transformer carries UL Listed certification and is NEMA TP-1 compliant, with catalog notes highlighting NEMA TP-1 efficiency. These certifications facilitate code compliance in industrial installations, reduce procurement risk, and support shared responsibility in audits and vendor qualification. The electrostatic shielding further enhances EMI performance in sensitive environments.
Maintenance benefits come from its robust 80°C rise insulation, aluminum windings, and rigid compliance features that minimize failure modes in harsh environments. ROI is driven by reduced downtime from stable voltage with tap adaptability, lower energy losses due to efficient design, and longer service life from heat mitigation and EMI control, ultimately decreasing lifecycle costs.
