Newmar 115-24-10 Power Supply 115/230VAC To 24VDC @ 10 Amps Product Description
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.

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.
Frequently Asked Questions
What input voltages does the Newmar 115-24-10 support?
It accepts 105-125 VAC or 210-250 VAC via a front-panel slide switch, with derating to 50% output below 110/220 VAC thresholds. Perfect for varying shore power or generators.
How does intermittent rating differ from continuous on this power supply?
Intermittent allows 10A for up to 20 minutes at 20% duty cycle, ideal for peak demands. Continuous handles 4A non-stop, 24/7, for steady loads like radios.
Is the Newmar 115-24-10 suitable for saltwater marine environments?
Absolutely—conformal-coated boards and corrosion-resistant aluminum housing make it thrive in salty, humid conditions with shock mounts for vibration resistance.
What protections does it offer against faults?
Overvoltage shutdown, current limiting at 105% rating, thermal overload, and input/output fusing safeguard both the supply and connected equipment.
Can I adjust the output voltage, and what's the range?
Yes, internally adjustable from 21-27.5 VDC, nominally set at 24.5 VDC for fine-tuning to specific 24V system needs.
What is the ripple level, and why does it matter?
Less than 70 mV peak-to-peak, ensuring ultra-clean DC for noise-sensitive electronics like navigation instruments—prevents data errors or signal interference.
How hot can this unit operate in engine spaces?
Full power up to 40°C, derating linearly to 50% at 50°C ambient, with auto-shutdown at 85°C case temp for safety.
Heavy Duty Series
