FAQs
Yes. This three-phase transformer is rated for a 480 V primary and 208Y/120 V secondary, designed for standard industrial distribution. It includes voltage taps (+2.5% and -2.5%) to maintain output under load or fluctuations. It operates at 60 Hz and uses copper windings to support reliable control cabinet and machine applications.
The unit incorporates K-Factor 13, indicating enhanced non-linear load handling and reduced heat under harmonic conditions. This improves overall efficiency and longevity in power-dense automation systems. When paired with DOE 2016 efficiency targets and an 80 °C insulation rating, it helps meet regulatory requirements while supporting delicate loads in manufacturing lines.
Yes. It is built with a NEMA 2 enclosure and a FR943 frame suitable for floor or wall mounting in harsh environments. With dimensions roughly 31.5 in x 34.5 in x 51 in and a 50 dB sound profile, it integrates into control rooms and equipment bays while meeting safety and installation standards.
It carries UL Listed certification and aligns with DOE 2016 efficiency requirements under 10 CFR Part 431. The product notes also reference 2016 efficient standards, providing a robust safety profile suitable for industrial power distribution in panels, cabinets, and automation systems.
Expect lower operating costs due to DOE 2016 efficiency and quiet operation at 50 dB. The electrostatic shield and WS60 weather shield reduce EMI and environmental risk, while the 75 kVA rating supports growth without additional transformers. A one year warranty (or 18 months from shipment) contributes to faster ROI and reduced downtime in production lines.
