32-12-35 DC Converter
Convert 20-50 VDC input to 12 VDC negative ground output for powering communication and navigation equipment on negative ground systems. (See Isolated Series for positive ground applications.)
Features:
- Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within the rating
- The heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and the long life of components
- Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts assure survival in hostile environments
Numerous Converter & Load Protection Circuits:
- Current limiting

Option: Extreme Vibration Mounting Kit
The Extreme Vibration Mounting Kit is available to protect NEWMAR power converters from the extreme stresses of shock and vibration when mounted on high-vibration vehicles. The kit replaces the standard vibration kit provided with the unit. It fits into the unit’s mounting flange to act as a ‘super shock absorber’ for electronics in high-vibration applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify KIT L for units that weigh 2–15 lbs. and Kit H for 16–7 lbs.
