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 115-24-18CD is a super-rugged 24-volt DC linear power supply designed for powering communication and navigation equipment on commercial vessels where reliability is critical. This proven linear circuit design delivers pure, noise-free output with exceptional long-term durability in harsh marine environments.

Key Features:

  • Linear circuit design provides clean, noise-free DC power ideal for sensitive electronics
  • Excellent voltage regulation maintained within 1% under all rated line and load conditions
  • Polyurethane conformal-coated PC board protects against moisture and corrosion
  • Heavy-duty powder-coated aluminum heat sink case with integral shock mounts
  • Large heat sink fins extract and dissipate heat for cool, reliable operation
  • Thermally-activated cooling fan ensures optimal performance under load
  • Comprehensive protection: overvoltage, current limiting (105% of intermittent rating), thermal overload, and input/output fusing
  • Front panel terminal block for easy installation
  • Selectable 115/230 VAC input voltage

Technical Specifications:

  • Output Voltage: 24.5 VDC (internally adjustable 21-27.5 VDC)
  • Continuous Output: 4 amps (24 hours/day, 100% duty cycle)
  • Intermittent Output: 10 amps (20 minutes max, 20% duty cycle)
  • Input Voltage: 105-125/210-250 VAC selectable, 50-60 Hz
  • Ripple: 70mV peak-to-peak maximum
  • Line and Load Regulation: 1%
  • Operating Temperature: 0-65°C (derate linearly from 100% at 50°C to 50% at 65°C)
  • Thermal shutdown at 85°C case temperature
  • Dimensions: 5.7" H x 4.8" W x 16.3" D
  • Weight: 20 lbs

Optional Configurations:

  • Can be modified for use as a battery charger
  • Transfer relay available for automatic back-up battery switching (ERC option)
  • Custom output voltage adjustment within specified range

This power supply is built to survive hostile marine environments with its corrosion-resistant construction and conformal coating. The linear design ensures zero switching noise interference with VHF radios, GPS, and other sensitive navigation equipment.

Was very glad to find a place that carries unusual items.

Super Amazing

Amazon payment did not work, but paypal worked well and easy.

Michael was very understanding about my situation

Great prices. Very happy and very easy checkout. Thanks so much.

Website is easy to use.

thanx

Had exactly what I was looking for for a great price

Good user interface

so far so good

I had been searching many sites for a better price on shocks for my 1999 Ford Explorer, upon finding Autoplicity the savings was 13.00 cheaper than all others. I instantly made the purchase. wish i had knew about them before I purchased the other items for my truck. will return as a customer .
