Eaton V48M28T2216PVCU Solar duty transformer - DOE2016
Part Number: V48M28T2216PVCU
Quick Summary
The Eaton solar duty transformer is a robust, three‑phase solution designed to power solar‑ready facilities with 225 kVA capacity. Engineers often struggle to balance high efficiency, voltage stability, and rugged enclosure requirements in demanding outdoor or industrial environments. This model meets DOE 2016 Efficient standards, is UL Listed, and comes in a NEMA 2 enclosure, delivering reliable operation and safety under variable solar loading. With copper windings designed for minimal losses, it maintains transformer performance even during rapid load swings from sun‑driven generation. Its 480 V delta primary and 208Y/120 V secondary support seamless integration into existing electrical distributions, reducing retrofit risk and total cost of ownership, while WS61 weather protection adds another layer of resilience.

FAQs
Yes. The transformer is designed with a 480 V delta primary and 208Y/120 V secondary, enabling straightforward integration into existing distribution schemes. When planning installation, verify bus rating, protection coordination, and panel compatibility to ensure seamless operation and voltage accuracy under solar loading conditions.
The V48M28T2216PVCU is DOE 2016 Efficient, copper-wound, and engineered to minimize core and copper losses. This reduces idle and dynamic operating losses, lowering energy costs over the life of the installation. For solar applications, improved efficiency translates to lower heat rejection and better overall system performance during variable solar input.
Yes. The NEMA 2 enclosure with WS61 Weathershield provides robust protection suitable for indoor and semi-exposed environments. UL listed for standard electrical safety, it supports durable operation in controlled outdoor settings where moisture exposure is moderate and solar equipment requires consistent performance.
The dual tap settings allow fine voltage adjustment on the secondary side to compensate for fluctuations in solar generation and load. This improves voltage stability downstream, protects connected equipment, and reduces the risk of undervoltage or overvoltage conditions during rapid changes in sun exposure.
Key compliance points include DOE 2016 Efficient rating for energy performance, UL Listing for electrical safety, and enclosure ratings such as NEMA 2 for indoor/outdoor use. Additionally, catalog notes referencing 10 CFR Part 431 Efficient guidance help meeting federal efficiency standards in solar power installations.
