Newmar 12-12-3I Power Stabilizer

12-12-3i Power Stabilizer

Feed sensitive electronics with proper voltage, regardless of the battery condition. This stabilizing converter provides continuous, precisely regulated output over the entire range of a battery’s usable voltage. This prevents subjecting loads to fluctuating input voltage, which can cause shutdown, diminish performance, and possibly damage sensitive circuitry.

This converter provides total input/output isolation, virtually eliminating conducted line noise and permitting the connection of negative ground gear to positive or floating ground systems, or vice versa. It can be modified for use as a battery charger, allowing them to maintain a battery at a great distance from the primary voltage source, providing reserve power if the main source fails. The rugged anodized aluminum case is ideal for marine applications.

Application Benefits Include:

• Operate electronics at optimal input voltage, even from nearly drained batteries
• Boost voltage to compensate for voltage drops in long wire runs from batteries
• Eliminate voltage drops during momentary high current drain from batteries, as during engine start
• Eliminate voltage fluctuation from charge sources
• Eliminate voltage overshoot due to sudden removal of high current load

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 (pictured here) 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.
