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 115-12-20A is a heavy-duty linear DC power supply designed for marine and commercial vessel applications where reliable 12-volt power is critical. This rugged unit delivers 20 amps intermittent (8 amps continuous) output, making it ideal for powering communication equipment, navigation systems, and other essential 12V electronics in harsh marine environments.

Key Features:

  • Linear circuit design provides pure, noise-free DC output with minimal ripple (40mV peak-to-peak)
  • Exceptional voltage regulation maintains output within 1% under all rated line and load conditions
  • Polyurethane conformal-coated circuit board for moisture and corrosion resistance
  • Heavy-duty powder-coated aluminum heat sink case with integral shock mounts
  • Large heat sink fins extract and dissipate heat for cool, efficient operation
  • Comprehensive protection: overvoltage, current limiting (105% of intermittent rating), thermal overload, and input/output fusing
  • Dual voltage input: selectable 115/230 VAC operation (105-125 or 210-250 VAC, 50-60 Hz)
  • Front panel terminal block and heavy-duty mounting flange for easy installation

Technical Specifications:

  • Output Voltage: 13.6 VDC (internally adjustable 12.6-14.5 VDC)
  • Output Current: 20A intermittent (20 minutes max, 20% duty cycle) / 8A continuous (24/7 operation)
  • Input Current: 5.5A @ 115VAC, 2.5A @ 230VAC
  • Regulation: 1% line and load at 110-125/220-250 VAC input
  • Operating Temperature: 0-50°C (derate linearly from 100% @ 40°C to 50% @ 50°C)
  • Thermal shutdown at 85°C case temperature
  • Dimensions: 5.7" H × 4.8" W × 16.3" D
  • Weight: 20 lbs (9.1 kg)

Optional Features Available:

  • Battery charger modification
  • Custom output voltage adjustment within 12.6-14.5 VDC range
  • ERC transfer relay for automatic backup battery switchover during power failure

Built to withstand the demanding conditions of commercial marine operations, this power supply combines proven linear technology with robust construction for years of reliable service.
