FAQs
For shipboard installation, ensure adequate clearance for the 955 lb unit, secure mounting on a rigid base, and provide proper ventilation around the NEMA 2 enclosure. Use the rated 60 Hz supply and verify primary 450 V and secondary 120 V compatibility with the vessel's distribution panels. Consider tapping options to fine-tune voltage under load and ensure compliance with UL and ABS guidelines.
Key specs include a 112.5 kVA rating, 450 V primary, 120 V secondary, 60 Hz operation, copper windings, and a 115°C rise rating. The transformer is designed as a three-phase marine-duty unit with DT-3 capability, featuring taps for +2.5% and -2.5% adjustments and a NEMA 2 enclosure for rugged environments.
Yes. The unit is UL Listed and ABS Certified, reflecting compliance with safety and maritime standards. It uses a NEMA 2 enclosure and is designed with NEMA TP-1 efficiency in mind, supporting reliable operation in corrosive, humidity-heavy marine settings and enabling efficient energy use.
This 112.5 kVA, 450 V to 120 V marine-duty transformer is ideal for shipboard electrical systems, offshore platforms, and dockside power distribution where robust voltage conversion, weather resistance, and regulatory compliance are required. It supports critical loads while fitting into standard 3-phase distribution schemes.
Copper windings offer durable thermal performance and lower long-term energy losses, reducing maintenance frequency. The unit’s built-in taps simplify load matching, potentially lowering installation costs. A one-year warranty (or 18 months from shipment) provides initial protection, and UL/ABS certifications facilitate asset management and procurement decisions.
