Newmar 32-12-15 DC Converter

The 32-12-15 DC Converter is an essential power solution for marine and boating applications, enabling you to reliably convert 20-50 VDC input to a stable 12 VDC negative ground output. Ideal for powering communication and navigation equipment on various vessel types, this converter ensures optimal performance in even the most demanding marine electrical systems.

Features

• Exceptional Voltage Regulation: Maintains output voltage within 1% across all line and load conditions.
• Efficient Heat Dissipation: Large heat sink fins maximize air contact, ensuring cool operation and prolonging component lifespan.
• Durable Construction: Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts guarantee resilience in harsh marine environments.

Protection Circuits

Enhanced safety features protect both the converter and connected equipment:

• Current Limiting
• Automatic Thermal Shutdown
• Short Circuit Protection
• Reverse Polarity Protection
• Overvoltage Protection
• CE Certified

Options

• Battery Charger Operation: Can be configured to function as a battery charger or for parallel redundant operation. *Requires factory contact for derating to continuous duty rating.
• Extreme Vibration Mounting Kit: Protects the converter from extreme shocks and vibrations when mounted on high-vibration vessels.

Extreme Vibration Mounting Kit

The Extreme Vibration Mounting Kit is designed to shield your 32-12-15 DC Converter from the intense stresses of shock and vibration encountered on high-vibration marine vehicles. This kit replaces the standard vibration kit, fitting into the unit’s mounting flange to serve as a robust ‘super shock absorber’ for electronics in demanding applications. Available in Kit L for units weighing 2–15 lbs and Kit H for units weighing 16–70 lbs.
