Engineered for Uncompromising Reliability in Marine Environments

In the demanding world of commercial maritime operations, where constant vibration, salt-laden air, and fluctuating power sources test every piece of equipment, a dependable power supply isn't just an accessory—it's the backbone of your communication and navigation systems. The Newmar 115-24-35CD steps up as a heavy-duty powerhouse, converting 115/230 VAC inputs to a stable 24 VDC output at 35 amps continuous. Built to thrive in these harsh conditions, it ensures your critical gear stays online, no matter the storm.

What sets this unit apart is its battle-tested design for vessels where downtime isn't an option. From long-haul cargo ships to offshore support craft, operators trust it to deliver clean, regulated power that keeps radios humming, radars spinning, and navigation plots precise—without the flicker or dropout that lesser supplies suffer.

Robust Features That Deliver Marine-Grade Performance

• Precision Voltage Regulation: Maintains output within 1% across all load and line conditions, with ripple under 70 mV peak-to-peak. This means ultra-stable power for sensitive electronics, preventing data errors or signal interference common in rough seas.
• Hostile Environment Protection: Polyurethane conformal coating on the PC board shields against moisture and corrosion, while the rugged aluminum chassis with integral shock mounts absorbs impacts and vibrations that would sideline standard units.
• Advanced Thermal Management: Massive heat sink fins promote natural convection cooling, augmented by a thermally activated fan on CD models. This keeps components cool under full load, extending service life in engine rooms or exposed decks.
• Comprehensive Safeguards: Built-in overvoltage protection, current limiting at 105% of rating, thermal overload shutdown, and dual input/output fusing guard against faults, surges, and shorts—protecting both the supply and your downstream equipment.
• User-Friendly Design: Front-panel slide switch toggles between 115 and 230 VAC inputs effortlessly, with internal adjustability for fine-tuning output from 21-27.5 VDC to match specific system needs.

These aren't just specs on paper; they're proven in real-world deployments where reliability translates to safer voyages and fewer maintenance calls.

Detailed Specifications at a Glance

This compact yet hefty build fits seamlessly into tight bulkheads while handling the power demands of multiple high-draw devices.

Ideal Applications for Commercial and Offshore Use

Perfect for powering 24VDC systems on workboats, ferries, fishing vessels, and supply ships. It excels at feeding chartplotters, VHF radios, AIS transponders, autopilot drives, and lighting arrays—all while sipping shore power or generator input efficiently. In military auxiliary roles or remote sensing ops, its ruggedness shines, minimizing logistics headaches.

Captains and engineers appreciate how it bridges AC shore power to DC loads reliably, even during voltage dips from diesel gensets or grid inconsistencies at dockside.

Maximizing Longevity and Performance Tips

To get the most from your investment, mount it in a ventilated space away from direct saltwater spray. Regularly inspect fins for dust buildup and test protections annually. Pairing with quality cabling sized for 35A minimizes voltage drop, ensuring peak efficiency. In high-humidity zones, its conformal coating reduces cleaning frequency, but a soft brush keeps vents clear for optimal fan operation.
