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.

Product Details

The NewMar PT-24-45U is a professional-grade 24-volt battery charger designed for marine applications including workboats, military vessels, commercial vessels, and recreational craft. This intelligent charger delivers 45 amps of output across three isolated charging banks, utilizing advanced three-stage charging technology to optimize battery performance and longevity.

Smart Three-Stage Charging Technology:

The PT-24-45U automatically progresses through bulk, absorption, and float charging stages to provide the ideal charge profile for your batteries. A convenient selector switch adjusts output voltage to match gel-cell, flooded lead-acid, or AGM battery types, ensuring compatibility with virtually any 24-volt battery system. The charger is recommended for battery banks ranging from 90 to 450 amp-hours.

Key Features:

  • Three isolated output banks with 45-amp total capacity; ammeter displays total output current
  • Universal input voltage: 90-264 VAC, 50-60 Hz with high power factor (.98 @ 115V, .95 @ 230V)
  • Battery type selector optimizes charge/float voltages for gel-cell, flooded lead-acid, or AGM batteries
  • Optional temperature compensation sensor (TCS-12/24) automatically adjusts voltage based on ambient temperature
  • Can function as a power supply to operate loads without batteries connected
  • Current limiting protection prevents damage from overloading
  • Compatible with optional remote panel (RP model) for charge cycle monitoring and manual re-initialization
  • Works with PT-MCU for enhanced control and monitoring capabilities
  • ABS type-approved for battery charging and power supply applications

Rugged Marine Construction:

Built to withstand harsh marine environments, the PT-24-45U features a robust stainless steel enclosure with durable white powder coat finish. Internal circuitry is polyurethane coated for maximum corrosion resistance. Protection features include current limiting, thermal protection, forced air cooling, and optional drip shield. Operating temperature range: -20°C to +70°C (output derates linearly from 100% at 50°C to 50% at 70°C).

Technical Specifications:

  • Input Current: 12A @ 115 VAC, 7A @ 230 VAC at full load
  • Output: 24V nominal, 45A maximum across 3 banks
  • Gel-Cell Mode: 28.0 VDC charge, 27.2 VDC float
  • Flooded/AGM Mode: 28.4 VDC charge, 26.8 VDC float
  • Dimensions: 14.8"H x 9.6"W x 5.6"D (add 1" height and 0.5" depth with optional drip shield)
  • Weight: 12 lbs
  • Compliance: UL 1950, USCG CFR 183.410 (ignition protected), EN 60335-1, CE marked, ABS approved
