Packed with protection features and high-efficiency circuitry, it’s the tool professionals trust.
Overview / What Is Newmar 32-12-15 Converter
The Newmar 32-12-15 Converter 20-50VDC To 13.6 Vdc 15A is a DC-DC power converter engineered to reduce high-voltage DC input (ranging between 20 and 50 volts) down to a steady 13.6VDC at a current output of 15 amps. This functionality is critical in boats using 24V, 36V, or 48V battery banks that still need to operate 12V devices.
This marine-grade converter eliminates the risks of voltage fluctuations, which can damage sensitive electronic components and disrupt operations. It is housed in a corrosion-resistant chassis and is vibration-tested for marine engine room environments, ensuring long-term durability.
Key Features of the Newmar 32-12-15 Converter

- Output: 13.6VDC @ 15 Amps, perfect for 12V systems.
- Marine Grade: Shock-proof, vibration-proof, and corrosion-resistant.
- Protections: Overload, short-circuit, thermal, and reverse polarity protection.
- Cooling: Passive cooling with heat sink design, fanless and quiet.
- Mounting: Compact design for horizontal or vertical mounting in tight spaces.
Why You Need a DC-DC Converter on Your Boat
Boats commonly operate with multiple voltage systems (24V, 36V, 48V) due to modern electronics and trolling motor setups. However, the majority of onboard electronics like VHF radios, GPS systems, autopilots, and fish finders operate at 12V. A product like the Newmar 32-12-15 Converter 20-50VDC To 13.6 Vdc 15A bridges this gap by offering stable, safe voltage conversion.
Moreover, without a converter, using resistors or voltage regulators may lead to overheating, instability, or failure. This converter ensures regulated power delivery, protecting expensive equipment. It’s a must-have for hybrid voltage marine systems.
Installation Best Practices for Newmar 32-12-15 Converter
Installing a DC-DC converter involves proper wiring, fuse protection, and ventilation. Here’s how to do it right:
- Mount the converter securely in a dry, ventilated location.
- Use marine-rated tinned copper wire of adequate gauge (10–12 AWG).
- Install input and output fuses as recommended (20A rated fuse on the output line).
- Double-check polarity connections. Incorrect wiring can trigger protection mode.
- Allow 1–2 inches clearance on all sides for heat dissipation.

Maintenance Tips
To ensure long-term efficiency, the Newmar 32-12-15 Converter 20-50VDC To 13.6 Vdc 15A must be periodically checked and maintained. Follow these steps for worry-free use:
- Inspect wiring terminals quarterly for corrosion or oxidation. Use dielectric grease on terminals.
- Clean the heat sink using compressed air to prevent dust buildup that can cause overheating.
- Check output voltage using a multimeter every 6 months to ensure it delivers exactly 13.6V.
- Examine for any burnt smell or discoloration that may indicate overload or internal fault.
Understanding Voltage Drops in Marine Systems
Voltage drop is a critical issue in marine DC wiring. When a DC device is installed far from the power source, especially in large boats, voltage loss can lead to equipment underperformance or failure. The Newmar 32-12-15 converter is strategically designed to eliminate this by being installed closer to the equipment requiring 12V power.
This approach ensures minimal voltage drop and enhances operational reliability. Boats using trolling motors, underwater lights, or livewell systems will greatly benefit from this efficient local voltage regulation strategy.
Expert Advice and Pro Recommendations
Marine technicians and electricians highly recommend the Newmar 32-12-15 Converter 20-50VDC To 13.6 Vdc 15A for all vessels transitioning to mixed-voltage systems. It works seamlessly with AGM, Lithium, and Flooded battery types.
For optimized results:
- Pair with proper gauge wiring and circuit protection.
- Use it for powering electronics that need low noise DC supply.
- Consider installing more than one for systems drawing over 15 amps cumulatively.

Detailed FAQ Section
What makes the Newmar 32-12-15 converter different from other models?
The Newmar 32-12-15 converter is purpose-built for marine environments, with a wide input voltage range (20–50VDC) and precisely regulated output (13.6VDC @ 15A). Unlike generic converters, it’s designed to withstand vibration, salt air, and heat. It uses passive cooling (no fan noise or moving parts) and includes safety protections such as reverse polarity, over-voltage, and thermal shutdown.
How to properly install the Newmar 32-12-15 converter on a yacht?
Begin by selecting a well-ventilated and dry mounting area close to the load. Secure it using stainless steel fasteners. Connect input wires from your DC source (24V or 36V battery bank), ensuring positive and negative are correctly aligned. Connect the output wires to your 12V device. Always use marine-grade wires and fuses rated for 20A on the output and 15–25A on the input depending on the source voltage. Double-check polarity before powering up the system.
What are the signs of failure or malfunction in the DC-DC converter?
Indicators include voltage output fluctuation, device shutdowns, burnt smell, unit heating beyond expected levels, or the fuse tripping repeatedly. You may also hear buzzing if there’s an internal component fault. Use a multimeter to confirm consistent 13.6V output. If deviations persist, isolate the unit, inspect the terminals and consult with a technician.
Can the converter be used with lithium batteries?
Yes. The Newmar 32-12-15 converter works with lithium battery setups, including LifePO4. It provides a consistent voltage that lithium-powered systems require. However, if you’re using smart BMS-enabled lithium batteries, ensure the converter output is isolated from feedback loops. Proper grounding is essential for safe lithium integration.
What is the typical lifespan of the Newmar 32-12-15 converter?
With regular maintenance and clean installation, the converter typically lasts over 7–10 years. Its design incorporates high-quality capacitors, sealed circuitry, and corrosion-resistant metal casing. It performs well in both commercial and recreational settings when installed correctly and not overloaded. Periodic checks every 6 months will significantly prolong its service life.
Conclusion
The Newmar 32-12-15 Converter 20-50VDC To 13.6 Vdc 15A is the most reliable DC-DC solution for boats, yachts, and marine engine systems requiring stable 12V output from a higher voltage supply.
