FAQs
Plan for mounting in a 914D frame enclosure with adequate ventilation. Connect 480 V primary to the supply and 480Y/277 V secondary to the load, verify tap settings (+2.5% FCAN, -2.5% FCBN) to match site voltage, and ensure the WS39 weather shield is used if installed outdoors. Confirm UL Listed safety compliance and allow clearances per local code.
K-13 nonlinear design provides a defined K-Factor to manage harmonic distortion, reducing winding heating and improving voltage regulation under non-linear loads. This translates to better efficiency, longer transformer life, and more stable equipment operation in drives and PLC-controlled environments.
Yes. With 45 kVA capacity, 480 V to 480Y/277 V secondary, and features like aluminum windings, electrostatic shielding, and WS39 weather shield, it is well-suited for data centers and industrial plants needing reliable power quality, effective EMI control, and robust outdoor or harsh-indoor installation options.
The N48M47F45A is UL Listed, confirming electrical safety and reliability. This certification supports regulatory compliance in North American installations and offers assurance to procurement and safety teams during audits and maintenance planning.
Low maintenance needs stem from robust aluminum windings and sealed shielding, while the ventilated design keeps operating temperatures under control, reducing energy waste. The selectable taps improve voltage regulation, minimizing wear on connected equipment and driving cost savings through improved uptime and reduced service interruptions.
