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.

  • 40-amp output with three isolated charging banks for independent battery management
  • Adjustable battery type selector for gel-cell, flooded lead-acid, or AGM batteries with optimized charge profiles
  • Universal input voltage (90-264 VAC, 50-60 Hz) with excellent power factor (.98 @ 115V)
  • Rugged stainless steel case with white powder coat finish and polyurethane-coated internal circuitry for maximum corrosion resistance
  • Can function as a regulated power supply to run loads directly without battery connection
  • Current limiting protection prevents damage from overloading
  • Built-in ammeter displays total output current across all banks
  • Optional temperature compensation sensor (TCS-12/24) adjusts output voltage based on ambient battery temperature
  • USCG ignition protected (CFR 183.410) and ABS-type approved for marine battery charging

Technical Specifications:

  • Input: 90-264 VAC, 50-60 Hz (6.8A @ 115V, 3.4A @ 230V)
  • Output: 40 amps maximum across 3 banks
  • Recommended battery capacity: 80-400 amp-hours
  • Output voltages: Gel-Cell mode (14.0V charge/13.6V float), Flooded/AGM mode (14.2V charge/13.4V float)
  • Operating temperature: -20°C to +70°C (derated linearly from 100% @ 50°C to 50% @ 70°C)
  • Dimensions: 13.85" H x 9.5" W x 4.8" D (add 0.75" height and 1.35" depth with optional drip shield)
  • Weight: 11 lbs

Optional Accessories:

  • Remote panel (EVM-12-2) for monitoring charger status and battery readiness of two banks
  • Temperature compensation sensor (TCS-12/24) with 25-foot cable (40-foot cable available)
