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.

Features:

• Wide range of input voltage
• Precise output voltage regulation
• Reverse polarity
• Input fuse/output fuse
• Total input/output isolation, pos. or neg. ground
• Current-limiting, short-circuit-proof output
• Automatic resetting of the thermal shutdown
• High/low input voltage shutdown
• Polyurethane conformal coating on PC board
• Power ON light
• Rugged case designed for high-vibration applications

Options:

• Operation as battery charger or parallel redundant operation* – derate to continuous duty rating (contact factory)
• Extreme vibration mounting kit. (Information below)

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.
