Why Choose the Newmar 115-24-10 for Your Marine Power Needs?

In the demanding world of commercial boating, where navigation and communication systems can't afford downtime, the Newmar 115-24-10 stands out as a rugged workhorse. This heavy-duty power supply converts 115 or 230 VAC input effortlessly to a stable 24 VDC output, delivering up to 10 amps intermittently or 4 amps continuously. Built specifically for harsh marine environments, it keeps your critical electronics humming reliably, even when salt spray, vibrations, and temperature swings try to take them down.

Imagine powering radar displays, VHF radios, or autopilot systems without worrying about voltage drops or noise interference. With its superior regulation—holding output steady within 1% across varying loads—and ultra-low ripple under 70 mV peak-to-peak, this unit ensures clean power that protects sensitive gear from glitches or damage.

Engineered for Extreme Reliability

• Versatile Input Selection: Front-panel slide switch toggles between 115 VAC and 230 VAC, adapting seamlessly to shore power or generator sources common on vessels.
• Hostile Environment Protection: Polyurethane conformal coating on the PCB shields against moisture and corrosion, while the aluminum chassis with integral shock mounts absorbs impacts and vibrations from rough seas.
• Advanced Thermal Management: Massive heat sink fins promote natural convection cooling for longevity, without relying on fans that could fail in dusty or salty conditions.
• Comprehensive Safeguards: Automatic overvoltage shutdown, current limiting at 105% of rating, thermal overload protection, and fused inputs/outputs prevent catastrophic failures and extend equipment life.
• Fine-Tune Output: Internally adjustable from 21 to 27.5 VDC (nominal 24.5 VDC), allowing precise matching to your system's requirements.

These features aren't just specs—they translate to peace of mind for captains and engineers who prioritize uptime over everything else.

Key Specifications at a Glance

Compact enough for tight engine rooms yet robust for offshore pounding, its footprint fits standard marine panels without hassle.

Ideal Applications in Commercial Marine Settings

This power supply shines in powering 24V DC systems on fishing trawlers, supply vessels, ferries, and research ships. Use it for:

• Navigation aids like GPS plotters and chart radars.
• Communication radios and AIS transponders.
• Control circuits for thrusters, winches, and lighting.
• Backup power for inverters or battery chargers during AC outages.

Engineers appreciate its military-grade durability, often outlasting lesser units in salt-laden air or engine heat. Pair it with solar or battery banks for hybrid setups, ensuring seamless failover.

Installation Tips from Marine Pros

Mount securely using the built-in shock mounts to combat vessel roll. Ensure ample airflow around heat sinks—avoid enclosing in tight cabinets. For best results, verify input voltage stability and use twisted-pair wiring for outputs to minimize noise pickup. Regular checks on fuses and adjustment pots keep it performing like new season after season.
