Asea Power

<h3>About ASEA Power Systems</h3><p><strong>ASEA Power Systems</strong> is a globally recognized leader in the design and fabrication of power conversion equipment engineered exclusively for the marine market. Founded in 1999 and headquartered in Costa Mesa, California, ASEA has spent over two decades solving some of the most demanding electrical challenges faced by yacht owners, marina operators, shipyards, and superyacht builders worldwide.</p><p>ASEA Power Systems is a world leader in the design and fabrication of power conversion equipment specially designed for the marine market, with products ranging in power from 8 to 1000+ kVA in both air and liquid-cooled variations. This diverse range includes shore power converters, dock boost transformers, dock locker converters, isolation transformers, clean grid converters, and even custom-engineered solutions.</p><h3>Engineering for Safety and Reliability</h3><p>What sets ASEA apart is their unwavering commitment to safety at the dock. Every ASEA shore power converter is equipped with an isolation transformer for a crucial reason: safety — by isolating a ship&apos;s power system from shore power, the risk of fault current flowing through the water and endangering swimmers is eliminated. Their <a href="/16455-asea-power-isolation-transformers-200589">marine isolation transformers</a> are a cornerstone of this philosophy, engineered to protect vessels, crew, and surrounding marina environments from stray currents and galvanic corrosion.</p><p>The ASEA Isolation Transformer is certified to ABYC C-1500, UL 1500, and UL 1561 standards, making it safe for installation on gasoline-powered boats where ignition risk is a concern. By achieving compliance with the latest NEC 555.35 standard, the isolation transformer ensures marina electrical safety by preventing unintended ground-fault currents from exceeding GFPE thresholds, critical for avoiding tripping of dockside ELCI breakers and mitigating the risk of Electric Shock Drowning (ESD).</p><h3>Unmatched Customization and Global Reach</h3><p>ASEA takes pride in the exceptional level of customization its products offer, boasting 25+ enclosure styles, 3 cooling systems, and over 50 controls, alarms, and communication options. This makes ASEA a go-to partner for custom yacht builds and refit projects requiring tailored power solutions.</p><p>ASEA&apos;s products are trusted by yacht owners, marinas, and shipyards worldwide. Their global support network covers 127 countries and counting, with a broad network of trusted service providers strategically located in main ports across the globe. ASEA products are proudly made in the USA.</p><p>ASEA Power Systems is a brand of Mission Critical Electronics under the Marine Power Division. This backing ensures robust investment in research, engineering, and customer support — qualities that have made ASEA a preferred supplier to some of the largest superyacht builders and refit yards globally.</p><h3>Why Choose ASEA Power Systems?</h3><ul><li><strong>Safety-first engineering:</strong> Every product is built around galvanic isolation and electrical protection standards.</li><li><strong>Wide power range:</strong> Solutions scaled from small center-console vessels to mega-yachts requiring 1000+ kVA.</li><li><strong>USA manufactured:</strong> Built to rigorous quality standards at their Costa Mesa, California facility.</li><li><strong>Industry certifications:</strong> Products comply with ABYC, UL, and NEC marine electrical standards.</li><li><strong>Global service network:</strong> Support available in 127+ countries at key ports worldwide.</li></ul>

Product Details

The Asea Power Systems 634103 is a 12 KVA isolation transformer engineered as a direct drop-in replacement for the Charles ISOG2. Designed specifically for marine vessel applications, it protects underwater metal fittings from galvanic corrosion caused by shore power connections while shielding sensitive onboard electronics from electrical noise and ground faults present in marina shore power systems.

Key Features:

  • 12 KVA capacity — provides robust power handling suitable for most cruising and live-aboard vessels
  • Drop-in replacement for the Charles ISOG2 isolation transformer — no rewiring required
  • Isolates vessel AC system from shore power ground, eliminating the path for galvanic corrosion on underwater fittings, props, shafts, and through-hulls
  • Shields onboard electronics from shore power electrical noise and voltage spikes
  • Provides electrical safety by breaking the galvanic connection between the vessel and the marina's grounding system
  • Built for marine-grade durability in demanding aboard environments
  • Designed and manufactured by Asea Power Systems, a trusted name in marine electrical power solutions

Installing an isolation transformer is one of the most effective ways to protect a vessel's underwater metals from the damaging effects of galvanic and stray current corrosion when connected to shore power. The Asea Power 634103 delivers this protection in a proven, reliable package with a familiar form factor that simplifies installation for repower and refit applications.
