Copper windings provide superior conductivity and heat dissipation, reducing copper losses and enabling more efficient operation even under heavy load fluctuations. The business impact is lower energy waste and cooler operating temperatures, which translate to longer transformer life and reduced maintenance cycles in maritime environments. Applications include shipboard power systems and onboard distribution where reliability is critical for propulsion and hotel loads. Enclosure rating of NEMA 2 with WS19 weathershield delivers dependable protection against moisture and corrosion, enabling flexible deck or engine-room installation with fewer protective accommodations. The 112.5 kVA rating supports scalable loads while the 480 V to 240/120 V secondary configuration simplifies distribution to common marine equipment and auxiliary circuits. Taps at +2.5% and -2.5% allow on-site voltage fine-tuning to accommodate shipboard variations, improving voltage stability. Copper coil construction and 115°C rise rating contribute to rugged performance in vibration-prone environments, with a 60 Hz operating profile meeting typical maritime standards. The compact footprint and 916A frame, combined with a 945 lb weight, ease installation in constrained spaces without sacrificing robustness. Catalog notes highlight NEMA TP-1 efficiency, reinforcing energy-performance compliance alongside UL Listed and ABS Certified marks, which lowers regulatory risk and supports maintenance budgeting and long-term cost of ownership. Volume and weight considerations at 23.42 in length, 48.56 in height, and 28.22 in width ensure compatibility with common shipboard racks and mounting configurations, while the 3-phase design aligns with standard marine electrical distribution practices. Overall, this transformer delivers reliable, ship-ready power with built-in protection and efficiency features that help meet the demanding operating profiles of offshore vessels and coastal installations.

FAQs
Installers should plan for a durable, ventilated location with adequate clearance around the unit for cooling air and cable access. The transformer uses a NEMA 2 enclosure with WS19 weather shield, suitable for moisture-prone areas but not exposed deck environments without additional protection. Ensure proper mounting on a rigid base compatible with the 916A frame and verify cable sizing for 480 V primary and 240/120 V secondary circuits. Follow manufacturer torque specs and ensure compliance with UL and ABS requirements.
The unit is rated 112.5 kVA with a 480 V primary and a 240 delta/120 midtap secondary. It operates at 60 Hz and features taps at +2.5% FCAN and -2.5% FCBN to accommodate voltage variations in marine networks. Copper windings and a 115°C rise enable robust, efficient performance under variable load while maintaining regulatory compliance and safe operating temperatures in shipboard systems.
Yes. Designed for marine duty, this transformer provides reliable power conversion for propulsion and auxiliary loads. Its 112.5 kVA rating supports a range of onboard circuits, while the copper windings and 60 Hz operation ensure efficient energy transfer. The NEMA 2 enclosure and WS19 shield protect against marine contaminants, reducing maintenance needs and enhancing uptime on vessels and offshore platforms.
The MV48M22F12CUEE carries UL Listed and ABS Certified marks, signaling compliance with global electrical safety and marine industry standards. It is marketed as NEMA TP-1 efficient, which indicates energy efficiency standards for transformers under continuous duty. These certifications help satisfy regulatory requirements for shipboard equipment and facilitate procurement decisions in regulated maritime environments.
The copper windings reduce electrical losses, contributing to higher overall efficiency and lower operating costs over the transformer's life. The rugged NEMA 2 enclosure with WS19 shielding minimizes corrosion-related maintenance, while the +/− tap capability reduces voltage mismatch losses. Combined with UL and ABS certification, these factors lower downtime risk, extend service life, and improve total cost of ownership for marine power systems.
