Newmar 115-24-18CD Pwr Supply 115/230VAC To 24VDC @ 18A Cont Product Description
Keep your vessel's critical systems running smoothly even in the harshest offshore conditions with the Newmar 115-24-18CD power supply. This rugged unit converts 115/230 VAC input to a stable 24 VDC output at 18 amps continuous, making it ideal for demanding marine applications like powering radars, VHF radios, GPS systems, and navigation instruments on commercial ships and workboats.
What sets this power supply apart is its unwavering reliability. Built to shrug off corrosion, vibration, and extreme temperatures, it delivers consistent power without the fluctuations that can disrupt sensitive electronics. Imagine navigating through rough seas knowing your comms gear won't falter due to power glitches— that's the peace of mind this unit provides.
Rugged Design for Marine Endurance
- Corrosion-Resistant Build: Heavy-duty aluminum chassis with integral shock mounts and polyurethane conformal-coated circuit boards stand up to saltwater spray, humidity, and constant vessel motion.
- Advanced Cooling: Massive heat sink fins paired with a thermally activated fan ensure components stay cool under full load, extending service life in engine rooms or exposed decks.
- Precision Regulation: Output voltage holds steady within 1% across varying line and load conditions, with ultra-low ripple (under 70 mV peak-to-peak) to protect delicate navigation gear from noise interference.
- Comprehensive Protections: Safeguards against overvoltage, current limiting (at 105% of rating), thermal overload, and fused inputs/outputs prevent damage from surges or faults.
- Versatile Functionality: Switch-selectable 115/230 VAC input via front-panel slide switch, and it doubles as a reliable battery charger for 24V systems.
Performance You Can Count On
Engineered for 100% continuous duty at 18A or intermittent peaks up to 18A (20 minutes max, 20% duty), this supply operates from 0°C to 50°C, derating linearly to 50% at 50°C with automatic thermal shutdown at 85°C case temp. Input range spans 105-125/210-250 VAC at 50/60 Hz, with derating below nominal for tough power scenarios.
Compact yet powerful at 6.5"H x 9.5"W x 14"D and 32 lbs, it fits seamlessly into tight console spaces without sacrificing output. Internally adjustable output (21-27.5 VDC) allows fine-tuning for specific equipment needs.

Perfect for Commercial Marine Operations
On tugs, ferries, fishing vessels, or offshore supply ships, reliable DC power is non-negotiable. The 115-24-18CD powers everything from autopilot systems to chartplotters and AIS transponders, minimizing downtime and enhancing safety. Its heavy-duty construction means fewer replacements and lower long-term costs compared to lesser units that fail under real-world stress.
Captains and engineers praise its quiet operation—no distracting displays or unnecessary features—just rock-solid performance. Pair it with battery banks for hybrid setups, leveraging its charger capability to maintain charge during generator runs.
Pro Tips for Installation and Maintenance
- Mount securely using built-in shock mounts to combat vibration.
- Ensure adequate airflow around heat sinks for optimal cooling.
- Periodically inspect fuses and clean vents to maintain peak efficiency.
- Test output adjustment annually to match evolving equipment demands.
