FAQs
Plan for proper ventilation and clearance around the ventilated frame, and mount the transformer in a well-ventilated cabinet or pad area. Use the 283B wiring connection and plan for M-Taps to allow voltage flexibility. Follow manufacturer torque specs, secure connections to minimize vibration, and verify UL-listed installation with local codes. Schedule routine checks for airflow and heat dissipation paths.
Its K-Factor nonlinear design helps mitigate harmonic distortion and reduces peak losses, improving efficiency under nonlinear loading. The integrated K13 feature enhances performance, while the DOE2016 Efficient rating supports sustained energy savings. This combination is particularly valuable for drives, variable speed equipment, and mixed-load automation panels where harmonics are common.
Yes. The N48M28T1221CULS50 is UL Listed, ensuring safety compliance, and carries DOE2016 Efficient designation, meeting contemporary energy performance targets. These certifications reduce compliance risk in procurement, simplify installation in regulated environments, and support long-term operating cost reductions across industrial facilities.
Absolutely. With a 112.5 kVA rating, three-phase configuration, and 480 V to 208Y/120 V outputs, it suits data center power conditioning and factory automation panels. The 50 dB sound profile facilitates quieter operation in mixed-use facilities, and M-Taps provide voltage flexibility for future-proofing and easier integration with existing switchgear.
Expect lower energy losses due to the DOE2016 Efficient design and reduced thermal stress from the ventilated construction, contributing to a shorter payback period. UL listing adds reliability and easier maintenance planning. The K-Factor approach minimizes harmonic-related wear, potentially reducing maintenance intervals and extending transformer life in high-demand automation environments.
