The 32-12-50 DC Converter is an essential power solution for marine and boating applications, delivering a stable 12 VDC negative ground output. Designed to operate with input voltages ranging from 20 to 50 VDC, this converter ensures your communication and navigation equipment receives consistent and reliable power, even in challenging marine environments.
Features
- Excellent Regulation: Maintains output voltage within 1% across all line and load conditions, ensuring your marine electronics perform optimally.
- Efficient Heat Dissipation: Large heat sink fins effectively extract and dissipate heat generated by semiconductors, promoting cool operation and extending component lifespan.
- Durable Construction: Features a polyurethane conformal coating on PC boards and a corrosion-resistant anodized aluminum case with heavy-duty shock mounts, ensuring survival in harsh marine environments.
Protection Circuits
Engineered with multiple protection mechanisms to safeguard your equipment:
- Current Limiting: Prevents excessive current draw, protecting both the converter and connected devices.
- Automatic Thermal Shutdown: Automatically shuts down the converter if internal temperatures exceed safe limits.
- Short Circuit Proof: Protects against short circuits, preventing potential damage.
- Reverse Polarity Protection: Ensures safe operation even if the input connections are reversed.
- Overvoltage Protection: Shields your equipment from voltage spikes and surges.
- CE Mark Certified: Complies with European safety standards for quality and reliability.

Mechanical Specifications
- Powder-coated aluminum heat sink case for enhanced durability and heat management.
- Front panel terminal block for easy and secure wiring connections.
- Heavy-duty mounting flange ensures stable installation on your vessel.
- Conformal coated PC board protects internal components from moisture and corrosion.
Options
- Battery Charger or Parallel Redundant Operation: Allows the converter to function as a battery charger or operate in parallel for redundant power. Contact the factory to adjust to the continuous duty rating.
- Extreme Vibration Mounting Kit: Enhances durability by protecting the converter from extreme shocks and vibrations common in high-vibration marine environments.
Option: Extreme Vibration Mounting Kit
The Extreme Vibration Mounting Kit is designed to safeguard your DC Converter against the severe stresses of shock and vibration encountered in high-vibration marine applications. This kit replaces the standard vibration mounts, transforming the mounting flange into a superior shock absorber. Compatible with all NEWMAR units weighing between 2 to 70 lbs., choose KIT L for units between 2–15 lbs. and KIT H for units between 16–70 lbs.
Note: This product cannot be returned to the original point of purchase. For any issues or concerns, please contact the manufacturer directly.
