Newmar 12-24-25 Step Up DC-DC Converter 25 Amp Conitnuos
Newmar 12-24-25 Step Up DC-DC Converter 25 Amp Conitnuos — Product description
Power Your Marine Electronics with Reliable 12V to 24V Conversion
Running high-demand electronics like radars, thrusters, or specialized navigation gear on a boat often means dealing with mismatched voltage systems. The Newmar 12-24-25 Step Up DC-DC Converter bridges that gap seamlessly, transforming your robust 12-volt house battery setup into a steady 24-volt supply. Without the hassle of adding a separate 24V battery bank or complex charging infrastructure, this unit delivers 25 amps continuous power—perfect for marine applications where space, weight, and simplicity matter most.
Engineered for negative ground systems, it handles real-world marine conditions with ease: fluctuating inputs from alternators or batteries, temperature swings, and vibration. Boat owners appreciate how it eliminates voltage drops that can glitch sensitive equipment, ensuring smooth operation during long passages or heavy use.
Robust Features for Demanding Environments
- High-Efficiency Conversion: Up to 93% efficiency means less heat buildup and wasted energy, keeping your system cooler and more reliable on extended voyages.
- Built-In Protections: Current limiting prevents overloads, voltage spike suppression shields gear from surges, and automatic thermal shutdown with recovery protects against overheating without manual intervention.
- Low Ripple Output: Under 100mV peak-to-peak ensures clean power for finicky electronics like chartplotters or sonar that hate noisy DC.
- Rugged Construction: Anodized aluminum and glass-filled polycarbonate case offers IP53-level resistance to dust, water splashes, and impacts—ideal for engine rooms or exposed deck mounts.
- Easy Monitoring: Green LED indicator confirms output status at a glance, simplifying troubleshooting at sea.

Installation Tips for Optimal Performance
Mount in a well-ventilated spot away from heat sources. Use appropriately sized wire (e.g., 6-8 AWG for inputs/outputs) to minimize voltage drop—aim for under 3% loss. Fuse both input and output sides close to the source. For best results, connect to your house bank rather than starter battery to avoid alternator strain. Test under load before heading out to confirm stable output.
Pro tip: Pair with a battery monitor to track your 12V source health, as converters draw significant current (up to 50A at full load).
Ideal Applications in Marine and Beyond
From sailboats powering windlasses to power yachts running bow thrusters, this converter shines where 24V devices meet 12V systems. It's also a go-to for RVs with 24V inverters or off-grid setups needing dual-voltage flexibility. Skip the extra batteries—leverage your existing power plant efficiently.
Frequently Asked Questions
Can this converter handle full 24-hour continuous use at 25 amps?
Yes, it's rated for 100% duty cycle continuous operation at 25 amps, making it suitable for steady loads like marine electronics or pumps without downtime.
What protections does the 12-24-25 offer against marine hazards?
It features current limiting, surge suppression, thermal shutdown with auto-recovery, and an IP53-rated enclosure for dust, moisture, and impact resistance.
Is it suitable for positive or negative ground systems?
Designed specifically for negative ground systems, common in most modern marine and RV setups.
How does the output voltage hold up under varying input?
Output stays at 27.2V ±5% across the 10-15V input range, with tight regulation for line and load changes.
What's the difference between continuous and intermittent ratings?
Continuous is for unlimited runtime at 25A; intermittent allows short bursts (2 minutes at 20% duty) for peak demands like starting motors.
Can I use this on an RV or off-grid solar system?
Absolutely—its efficiency and durability make it versatile for RVs, trucks, or solar setups needing 24V from 12V batteries.
Does it require cooling fans or heatsinks?
No external cooling needed; passive design with thermal management handles full load up to rated temperatures.
These "UP" converters produce 24 volts from 12 volt systems and are ideal for managing dual voltage applications on marine vessels without having to install a 24 volt battery and dedicated charging system. Choose from two types depending on your application:
In the Standard, Non-Isolated Series the 12V input and 24V output share a common negative ground and are ideal when installing certain electronics that operate better on 24 volts when a robust 12 volt system exists. Models available in outputs of 7, 16 and 25 amps.
Standard, Non-Isolated Series
- Intended for use on negative ground systems
- 10 -15 VDC input range
- Available in 7, 16 and 25 amp outputs
- Current limited, voltage spike suppression, automatic thermal shutdown and recovery
