FAQs
Install with floor or wall mounting per the 51 in height and 34.5 in width footprint. Ensure 305K wiring connections are followed and the unit is placed on a level surface with adequate clearance for heat dissipation. Use shielded copper windings and verify the +/−2.5% tap positions are set to match system voltage. Proper securement reduces vibration and extends life.
It employs a K-Factor 13 nonlinear design and copper windings, which improve transformer efficiency under non-sinusoidal loading. DOE 2016 compliant efficiency further reduces no-load and load losses, leading to lower energy consumption over the life of the installation. This translates to measurable annual savings in facilities with variable loads and harmonic-rich environments.
Yes. The primary voltage is 480 V with a secondary of 400Y/231 V, rated at 75 kVA in a three-phase configuration. It’s designed for automation and manufacturing environments, providing stable voltage conversion and compatible grounding practices. The 150 °C rise rating supports operation under elevated ambient temperatures common in control rooms and equipment bays.
UL Listed certification confirms safety compliance for electrical equipment, while DOE 2016 Efficient endorsement ensures energy performance. The enclosure is NEMA 2 rated for indoor protection against dust and moisture, and the unit includes a shield to reduce EMI. These features help you meet regulatory audits and reduce risk in highly regulated environments.
Expect lower energy costs due to DOE 2016 efficiency and reduced heat load, leading to fewer cooling requirements and longer component life. The copper windings and robust insulation tolerate higher temperatures, while the shield and WS60 option reduce EMI-related failures. Overall, the ROI reflects energy savings, reduced downtime, and longer service intervals in demanding industrial applications.
