FAQs
The N48M28T3021CUHDI3 uses a 480 Vac primary and 208Y/120 Vac secondary configuration with a 30 kVA rating, designed for three-phase systems. When planning a panel, confirm available space for the 1093 lb unit, ensure adequate cooling around the vented enclosure, and verify mounting compatibility with standard transformer pads or racks. The UL Listed designation supports safe integration in regulated environments.
Its K-Factor nonlinear design handles non-sinusoidal loads without overheating, preserving transformer life and voltage quality in data centers and automation cabinets. The vented XFMR construction improves heat dissipation under harmonic loads from drives and controllers, while the 30 kVA rating matches medium-scale workloads. UL Listing further supports compliance in critical infrastructure environments.
Expect a substantial footprint and weight (approx. 1093 lb). Plan for floor loading, appropriate lifting equipment, and clearances for ventilation. Ensure electrical clearances for the vented enclosure and access for routine maintenance. Leverage compatible mounting accessories and consider nearby cooling provisions to maintain optimal operating temperatures and reliability.
K-Factor nonlinear transformers are engineered to tolerate harmonic currents generated by modern drives and power electronics. This reduces stray heat, limits insulation stress, and maintains better voltage regulation under non-ideal conditions, delivering more consistent performance and longer service life for critical loads in manufacturing and automation environments.
By delivering stable voltage quality with reduced thermal stress and lower maintenance needs, the N48M28T3021CUHDI3 supports higher uptime and fewer derating events. The UL Listed protection adds audit confidence, while the robust vented design enables sustained operation in demanding environments, contributing to lower lifecycle costs and improved overall equipment effectiveness (OEE).
