Newmar 12-12-35I DC Converter

12-12-35I DC Converter

This isolated series provides voltage conversion as well as input/output isolation, allowing the use of negative ground gear in positive or floating ground battery systems, or vice versa. 

Using an isolated converter as a voltage stabilizer on 12- or 24-volt systems can solve conducted noise and interference problems on sensitive DC-powered communication, navigation systems, and DC microprocessor-based devices.

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 and 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 units that weigh 16 – 70 lbs.
