With complete in-house manufacturing capabilities including CNC machining, PCB design and assembly, and comprehensive function testing, NewMar maintains exacting standards throughout the production process. This vertical integration ensures that every product meets the brand's stringent reliability requirements, making NewMar a trusted choice for professionals who depend on consistent power delivery.</p> <h3>Advanced Battery Charging Technology</h3> <p>At the heart of NewMar's product lineup is their proprietary Phase Three smart charging technology, which sets the standard for intelligent <a href="/11280-newmar-vehicle-battery-2476">vehicle battery</a> management. Unlike conventional chargers that can overcharge or undercharge batteries, NewMar's three-stage charging process—bulk, absorption, and float—optimizes charge cycles to maximize battery performance and extend service life. The chargers feature adaptive voltage regulation that automatically adjusts for different battery types including flooded lead-acid, AGM, and gel-cell configurations.</p> <p>NewMar battery chargers are engineered for hostile environments, with rugged stainless steel cases, polyurethane-coated circuitry for corrosion resistance, and sealed construction that prevents dust and moisture intrusion. These chargers can withstand the punishment of off-road vehicles, mining equipment, and marine installations where reliability is non-negotiable. Multiple isolated output banks allow simultaneous charging of separate battery systems, while integrated current limiting prevents damage from overloading.</p> <h3>Remote Starting and Power Accessories</h3> <p>Beyond battery charging, NewMar offers specialized power management solutions including <a href="/11280-newmar-remote-vehicle-starter-kit-14550">remote vehicle starter kits</a> designed for professional and recreational applications. These systems integrate with NewMar's broader power distribution ecosystem, providing seamless compatibility with battery integrators, DC converters, and power supplies.</p> <p>The brand's Battery Integrator products exemplify NewMar's engineering philosophy: intelligent solutions that solve real-world problems. These devices act as smart switches, connecting independent battery banks during charging while isolating them during discharge, allowing users to maintain separate house and engine-start batteries without voltage drop issues common to traditional diode isolators.</p> <h3>Built for Professional Applications</h3> <p>NewMar's commitment to quality has made their products the choice of professionals across multiple industries. From powering critical communications equipment in remote telecom sites to maintaining emergency vehicle battery systems in fire departments, NewMar products deliver when failure is not an option. The company's extensive product line includes DC power systems, inverter-chargers, UPS systems, and a full range of installation accessories, all backed by comprehensive warranties and technical support. Whether you're outfitting a commercial vessel, upgrading an emergency response fleet, or maintaining mission-critical equipment, NewMar provides the reliable DC power solutions that professionals demand.</p>

Product Details

The NewMar GI-60-FS Galvanic Isolator provides essential corrosion protection for marine electrical systems by blocking low-voltage DC currents while maintaining the critical AC safety ground connection. Designed to meet the latest ABYC A-28 2019 requirements, this 60-amp fail-safe unit installs between the AC safety ground and DC bonding system to prevent galvanic corrosion on underwater metallic components in saltwater environments.

How It Works:

By blocking low-voltage stray currents that cause galvanic corrosion, the GI-60-FS significantly extends the life of sacrificial zinc anodes and reduces corrosion on through-hulls, propellers, shafts, and other submerged metals. This translates to substantial savings in haul-out costs and anode replacement expenses. The unit features a large capacitor that provides a secondary low-impedance path for AC fault current to reach ground, ensuring electrical safety is never compromised.

Key Features:

  • 60-amp fail-safe design ensures continuous ground connection even if isolator fails
  • Meets ABYC A-28 2019 standards for marine galvanic isolators
  • UL1500 certified for ignition protection in marine environments
  • Rated for 50°C ambient temperature operation
  • Protects against stray currents up to 1.4 VDC
  • Compatible with 115-230V shore power systems
  • Maximum short circuit rating of 5000 amps
  • Compact design: 10.2" x 7.5" x 2.6" (260 x 190 x 65 mm)

Specifications:

  • Current Rating: 60 Amps
  • Shore Power Voltage: 115-230V AC
  • Stray Current Protection: Up to 1.4 VDC
  • Maximum Short Circuit: 5000 Amps
  • Operating Temperature: Up to 50°C ambient
  • Certifications: UL1500, ABYC A-28 2019
  • Dimensions: 10.2" L x 7.5" W x 2.6" H (260 x 190 x 65 mm)

This galvanic isolator is an essential safety and maintenance component for any vessel connected to shore power, providing robust protection against the costly effects of galvanic corrosion while maintaining full electrical safety compliance.

Just received the unit, I will update a review after installing the unit and a 90-day test/use period. Thank you

Very efficient

Easy

Easily-navigated website. Great purchase experience!

Not a lot dimension information on the boat cover stays,/bows. I hope they fit and work well. tbd
