Newmar Power 12-12-3i Power Stabilizer for Sensitive Electronics

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 batterys 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

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 units 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 KITL for units that weigh 215 lbs. and KitH for units that weigh 16-70 lbs.

The Newmar Power 12-12-3i Power Stabilizer is designed to provide precisely regulated voltage output for feed-sensitive electronics, ensuring optimal performance regardless of battery condition. This converter maintains a steady output of 13.6 volts at up to 3 amps continuously, effectively preventing voltage fluctuations that can cause system shutdowns, performance drops, or damage to delicate circuitry. Its robust anodized aluminum case makes it suitable for marine and rugged environments, offering durability and reliable operation in demanding conditions. The stabilizer features total input/output isolation, which virtually eliminates conducted line noise and allows for seamless connection of negative ground equipment to positive or floating ground systems, enhancing compatibility across various electrical setups. Additionally, it can be modified for use as a remote battery charger, enabling maintenance of batteries located at a distance from the primary power source, thereby providing reserve power during main source failure.

Application benefits include operating electronics at optimal input voltage even from nearly drained batteries, boosting voltage to compensate for drops in long wire runs, and eliminating voltage drops during high current demands such as engine starts. This stabilization reduces voltage fluctuation from charge sources and prevents overshoot when high current loads are suddenly removed, safeguarding sensitive components. The unit supports both intermittent and continuous duty cycles, with an efficient thermal shutdown feature at 70°C to protect internal components. With a switching frequency of 40 kHz and an efficiency of approximately 85%, it ensures minimal energy loss while maintaining stable voltage output. Its mechanical design includes a heavy-duty mounting flange and conformal-coated PC board for extra protection, making installation straightforward and secure.

Options such as factory modifications for battery charging, parallel/redundant operation, and high-vibration mounting kits are available to customize the unit for specialized applications. The Extreme Vibration Mounting Kit, in particular, provides enhanced shock and vibration absorption for high-vibration environments like off-road vehicles or marine vessels. Weighing just under 1/3 pound, the compact size allows flexible installation in tight spaces, making it an ideal choice for marine, automotive, or industrial use where reliable power stabilization is critical. Please contact the manufacturer directly for any custom configurations or application-specific modifications, as this product may not be returned to the point of purchase.
