Ensure reliable, noise-free power on your vessel with this robust 15kVA 60Hz isolation transformer designed specifically for marine environments. Engineered to deliver clean, isolated electricity from shore power sources, it protects sensitive onboard electronics from electrical noise, surges, and ground faults—common challenges when plugging into varying marina pedestals. Boat owners and marine professionals trust this unit for its superior shielding and rugged construction that stands up to harsh saltwater conditions.

Superior Power Protection for Marine Applications

In the demanding world of boating, inconsistent shore power can lead to flickering lights, humming appliances, and damaged AV systems. This transformer steps in as a critical barrier, fully isolating the boat's electrical system. By breaking the ground connection between shore and vessel, it eliminates stray currents that cause galvanic corrosion on hulls and through-hulls. Marine electricians often recommend it for yachts, sailboats, and workboats handling high-power loads like air conditioning, inverters, and chargers.

Key Advantages Over Standard Transformers

• Cleaner Power Delivery: Dual full current-carrying shields minimize electromagnetic interference, resulting in smoother operation for inverters, entertainment systems, and navigation gear.
• Weatherproof Durability: Fully encapsulated core and coil in electrical-grade silica and resin create an impenetrable seal against moisture, salt air, and contaminants. The UL Type 3R enclosure supports both indoor and outdoor installations, from engine rooms to dockside setups.
• Ultra-Quiet Performance: Advanced design keeps sound levels far below NEMA standards, ensuring peaceful nights at anchor without the drone of typical transformers.
• Extended Service Life: High-temperature UL-class insulation systems handle 115°C rise, with options up to 180°C for demanding loads, resisting breakdown from heat and vibration common in rough seas.
• Vibration Resistance: Built to absorb constant motion from waves and engines, preventing loose connections or mechanical wear over years of use.

Precision Engineering for Compliance and Flexibility

Every unit undergoes rigorous testing to surpass ABYC standards, including a 4000 Volt HIPOT test that verifies dielectric strength under extreme stress. UL listing and CSA certification confirm it meets NEMA, ANSI, and OSHA requirements, giving installers confidence in code-compliant setups. Adjustable 12.5% taps allow fine-tuning for voltage fluctuations at marinas, ensuring optimal performance from 120/240V inputs to match your boat's panel needs.

Compact Footprint for Easy Integration

Measuring just 16.94 inches high, 14.12 inches wide, and 11.69 inches deep, it fits seamlessly into tight spaces like lazarettes or electrical compartments without sacrificing power capacity. Weighing in at a manageable size for one-person handling, it's ideal for retrofits on mid-sized vessels up to 60 feet.

Ideal Use Cases in Boating

Perfect for powering multiple high-draw circuits simultaneously—think running a 5-ton AC unit alongside battery chargers and galley appliances. It's a staple for liveaboards combating "dirty power" from overloaded pedestals and for performance boats where every watt counts toward smooth propulsion auxiliaries. Pair it with a marine-rated cordset for a complete shore power solution that enhances safety and equipment longevity.

Simple Maintenance for Long-Term Reliability

Thanks to the sealed encapsulation, routine upkeep is minimal—just periodic visual inspections for enclosure integrity and secure mounting. No need for oil checks or frequent part replacements. In marine settings, this translates to fewer dockside headaches and lower ownership costs compared to air-cooled alternatives that degrade faster in humid climates.
