Detailed FAQ Section
What is the life expectancy of the Newmar 115-24-35CD Power Supply?
With proper installation and maintenance, the Newmar 115-24-35CD Power Supply can last over 10 years in marine environments. The marine-grade build and high-quality components are engineered for longevity. Periodic inspections, cleaning, and secure mounting help maximize its lifespan. Unlike consumer-grade units, Newmar’s design withstands humidity, vibration, and voltage spikes often found in boats.
Can I use this unit to charge batteries directly?
No. The Newmar 115-24-35CD Power Supply is not designed as a battery charger. It is a regulated DC power supply that provides constant 24VDC output. While you can use it to power DC systems that charge batteries through smart chargers, connecting it directly to a battery bank is not advisable due to lack of proper charge algorithms like absorption, float, and equalize stages required for marine batteries.
How do I know if I need 35 Amps?
You need to calculate the total amp draw of your 24VDC devices on board. Add the amperage for each device (lights, electronics, radios, etc.). If your total draw exceeds 25A with future expansion, the Newmar 115-24-35CD Power Supply gives you the overhead you need. For example, radar may draw 8A, chartplotters 6A, lighting 5A, leaving you little margin on smaller 20A supplies.
Is the unit protected against reverse polarity or overload?
Yes. The Newmar 115-24-35CD Power Supply has built-in overload protection and thermal shutdown. If the output current exceeds its rated 35A capacity, it will safely shut down or limit the current. Reverse polarity, however, must be carefully avoided during installation. Always follow wiring diagrams and color codes when connecting to your systems. Fuse blocks or breakers are recommended.
Does the fan run constantly or only under load?
The integrated fan in the Newmar 115-24-35CD Power Supply is temperature-controlled. It activates only when internal temperatures exceed a safe threshold, ensuring quiet operation under light or idle loads. This smart cooling design prevents dust buildup and prolongs fan lifespan. In high-load situations or hot environments, the fan will run more frequently to maintain safe temperatures.
Conclusion
The Newmar 115-24-35CD Power Supply is a trusted workhorse for marine professionals who demand clean, reliable 24V power. With its dual AC input compatibility, robust 35A continuous output, and intelligent cooling system, it’s engineered for demanding conditions. Whether you’re upgrading existing power systems or designing a new setup, this is a future-ready solution that’s worth every dollar. Don’t compromise on critical power delivery — choose Newmar for safety and performance.
