Feature → Business Impact → Application: The 150 kVA three-phase design supports scalable load distribution while maintaining compact footprint, enabling efficient power delivery in data centers and industrial plants. This K-Factor nonlinear transformer reduces harmonic stress on upstream equipment, improving reliability and extending component life in demanding environments. Copper windings enhance conductivity and thermal performance, resulting in lower losses and higher overall efficiency for continuous operation. With +2.5% / -2.5% taps, voltage regulation adapts to site fluctuations, minimizing equipment tripping and misoperation in facilities with variable supply. The WS34 Weathershield and electrostatic shielding provide rugged outdoor and EMI-prone installations with improved protection, reducing maintenance costs and downtime. A low sound profile of 47 dB helps facilities meet noise regulations and maintain a comfortable working environment, even in quiet data halls and control rooms. UL Listed and NEMA TP-1 compliant certifications simplify procurement and regulatory adherence, while a robust frame and weight support secure mechanical stability in rugged environments. This transformer is well-suited for critical power distribution between 480 V and 208Y/120 V systems, delivering reliable performance with reduced life-cycle costs.

FAQs
When installing the N48M28F49CUEELS47, ensure adequate clearance for cooling and access to connections, account for its 1745 lb weight, and mount using the 918A frame. Consider the WS34 weather shield if used outdoors, and plan for a 47 dB noise profile to meet plant acoustics requirements. Verify space for front-access terminals and allow for voltage taps (+2.5% and -2.5%) during commissioning to manage supply variations.
Key specs: 150 kVA, three-phase, primary 480 V, secondary 208Y/120 V, 60 Hz, copper windings, 115 °C rise. Taps are 2 at +2.5% and 4 at -2.5%, enabling voltage regulation to accommodate supply fluctuations and maintain load performance without external damping devices.
Yes. It is UL Listed and NEMA TP-1 compliant, ensuring adherence to recognized safety and efficiency standards for transformers in commercial and industrial spaces. The electrostatic shielding further protects sensitive equipment, and the low-noise output (47 dB) helps environments that require quiet operation.
Maintenance needs are typical for a 150 kVA copper-windings transformer; expect periodic inspection of connections and cooling paths. With a 115 °C rise design and robust Weathershield WS34, the unit provides extended service life in harsh environments, reducing replacement frequency. The included warranty policy (1 year from installation or 18 months from shipment) supports initial ROI as part of a wider power reliability strategy.
Best for data centers, manufacturing floors, and process facilities requiring reliable 480 V to 208Y/120 V distribution, 60 Hz operation, and harmonic control. The K-Factor nonlinear design helps mitigate harmonics, while the 150 kVA rating supports scalable loads and robust protection for critical equipment in controlled panels and outdoor sites with weather considerations.
