The unit is a marine-grade 10 kVA transformer rated for 60 Hz with 120 V input and 120 V output. This delivers consistent voltage to onboard systems, reducing nuisance trips and equipment incompatibility, and improving power quality across critical loads like lighting and hydraulic pumps. The device includes taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling on-the-fly voltage regulation without swapping transformers and supporting stable performance during motor starts and load shifts. Copper windings minimize I2R losses, improve efficiency, and extend service life, while an integrated electrostatic shield reduces EMI in noisy marine environments. NEMA 2 enclosure and WS15 weather shield provide rugged protection in damp spaces and exposed decks, easing installation and maintenance. The 815 frame supports compatibility with common rack and cabinet footprints in vessel power centers. With ABS approval and UL listing, procurement teams gain confidence in regulatory compliance, while a 1-year (or 18 months from shipment) warranty mitigates risk and supports total cost of ownership. Weight, dimensions, and mounting provisions are suitable for engine rooms and deck installations, enabling straightforward space planning and retrofit feasibility.

FAQs
RT12M12F10CUES is designed for shipboard power centers with a frame 815 footprint and NEMA 2 enclosure. Mounting should align with standard rack or cabinet layouts, ensuring clear air flow around the copper windings. The WS15 weather shield provides exterior protection for exposed deck installations. Installers should connect the 120 V primary and 120 V secondary to matching circuits and verify tap settings during commissioning.
This transformer features taps at two positions: +2.5% FCAN and four positions at -2.5% FCBN. Use the taps to compensate for voltage drop or supply deviations during load changes, maintaining voltage within tolerance for critical loads without swapping transformers. The correct tap choice should be determined during site surveys and validated during commissioning tests.
Yes. The unit provides 120 V primary and 120 V secondary, specifically supporting 120/120 V distribution on vessels. Its 10 kVA rating covers typical control panels, lighting, and auxiliary systems, while the copper windings improve efficiency and heat dissipation under continuous duty. For motor loads, ensure start-up surge is within transformer capacity.
RT12M12F10CUES carries ABS certification and UL listing, indicating compliance with marine safety standards and electrical reliability. These certifications help meet regulatory requirements for shipboard equipment, support risk management, and facilitate procurement by validating product suitability for harsh environments and critical operations.
Maintenance is typically straightforward due to copper windings and a robust NEMA 2 enclosure with WS15 protection. Regular visual inspections and insulation checks, plus temperature monitoring, help sustain performance. ROI is enhanced by high reliability, reduced downtime, and adaptability via taps, which minimize replacement costs and support longer service life in demanding maritime applications.
