    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

    Specifications:

    • Input Voltage: 10-16
    • Input Amps: 4
    • Output Voltage: 13.6
    • Output Amps (Intermittent): 3
    • Output Amps (Continuous): 3

    • Continuous: 24 hours, 100% duty
    • Idle Current: Less than 100 mA (including power “ON” light )
    • Operating Temp: 0-50 degrees C, Derate Linearly From 100% @ 40 degrees C To 50% @ 50 degrees C. Thermal shutdown @ 70 degrees C Case Temperature.

    • Efficiency: 85% – Typical.
    • Isolation – Output/Chassis; Input/chassis: 250 VDC

    Mechanical Specifications:

    • Anodized aluminum heat sink case
    • Front panel terminal block
    • Heavy-duty mounting flange
    • Conformal-coated PC board

    Options/Factory Modifications:

    • Operation as a battery charger (contact factory)
    • Parallel/redundant operation (contact factory)
    • High-vibration mounting kit
    • Non-standard output voltage (contact factory)

    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.

    Product & Usage

    1. Is your gear authentic and warranty-backed?

    Yes — we are an authorized US dealer for 300+ marine electronics brands. Every order ships with the manufacturer’s full warranty.

    2. Are these products beginner-friendly?

    Yes. Our products are designed for both seasoned boaters and first-time owners. Each unit ships with a manufacturer manual, and we’re happy to answer setup questions over email.

    3. Are these products built for marine conditions?

    Yes. Marine electronics are engineered for saltwater spray, vibration, and weather. Check the product specs for IPX waterproof rating and saltwater certifications.

    Maintenance & Accessories

    1. What maintenance does marine electronics require?

    Rinse with fresh water after saltwater exposure, store in a dry place, and follow your manufacturer’s cleaning and storage instructions.

    2. Can I buy replacement parts and accessories separately?

    Yes — we carry replacement parts, mounts, transducers, cables, and accessories for the brands we stock.

    3. Do you provide product manuals or installation guides?
