NewMar

<h3>NewMar: Trusted DC Power Solutions for Over Five Decades</h3> <p>NewMar has established itself as a premier manufacturer of high-quality DC power products, bringing more than 50 years of engineering excellence to the automotive, marine, and telecommunications industries. Known for their rugged construction and intelligent charging technology, NewMar products deliver reliable performance in demanding environments ranging from emergency service vehicles to off-shore marine applications.</p> <p>The company's reputation is built on a foundation of innovation and quality control. 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 32-12-50 is a high-performance DC-DC converter designed to convert 20-50 VDC input to 13.6 VDC negative ground output, ideal for powering communication and navigation equipment on marine, RV, and mobile applications. This rugged converter delivers 50 amps intermittent (20 minutes max) or 40 amps continuous output with exceptional reliability.

Key Features:

  • Precision voltage regulation within 1% under all line and load conditions
  • Large heat sink fins extract and dissipate heat for cool operation and extended component life
  • Polyurethane conformal coating on PC boards for protection in hostile environments
  • Corrosion-resistant anodized aluminum case with heavy-duty shock mounts
  • 40 kHz switching frequency with 85% typical efficiency
  • CE marked for compliance

Comprehensive Protection Circuits:

  • Current limiting with automatic thermal shutdown at 70°C case temperature
  • Short circuit proof design
  • Reverse polarity protection
  • Overvoltage protection

Technical Specifications:

  • Input Voltage: 20-50 VDC
  • Output Voltage: 13.6 VDC (internally adjustable 12.6-14.5 VDC)
  • Output Current: 50A intermittent / 40A continuous
  • Ripple: 150 mV peak-to-peak maximum
  • Regulation: 1% line and load
  • Isolation: 250 VDC output/chassis and input/chassis
  • Idle Current: Less than 100 mA including power indicator light
  • Operating Temperature: 0-50°C (derate linearly from 100% at 40°C to 50% at 50°C)

Construction:

  • Powder-coated aluminum heat sink case
  • Front panel terminal block for easy connections
  • Heavy-duty mounting flange with shock mounts included
  • Conformal coated circuit boards for harsh environment protection

Optional extreme vibration mounting kits are available for high-vibration vehicle applications. The converter can also be configured for battery charger or parallel redundant operation when derated to continuous duty rating.
