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
  • Case Size (H x W x D): 3.5 x 3.5 x 1.75 inches (8.9 x 8.9 x 4.5 centimeters)
  • Weight: 1 lb. (.45 kg)
  • Output: 12 or 24V, nominal, see matrix
  • Ripple: 150 mV P-P maximum
  • Regulation: 1% Line/Load

Duty Cycle Ratings:

  • Intermittent: 20 minutes max on time, 20% duty. Current limit is set at approx. 105% of intermittent rating.
  • 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.
  • Switching Frequency: 40 kHz.
  • 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.

Good budget watch
Color: 2926 Silver Stainless Steel/Black Dial
Good watch for a budget, color is good. The pins holding the link together tend to wear out and fall out. Other than that it worked good.

Nice Watch
Color: 5885 Siver Stainless Steel/hon Dial, Color: 5885 Siver Stainless Steel/hon Dial
Nice watch for the money. I've only had it a week but seems to be keeping good time. From 20 feet away might be mistaken for "Trump Time". The watch design is actually a copy of the Rolex Submariner for a whole lot less money. Several watch companies have copied the Submariner. I removed one link at a time when resizing the band. By the time I got to the final link, the supplied tool wasn't working. I had to remove the final link with a hacksaw and pliers.

DIDN'T LAST LONG
Color: 5885 Gold Stainless Steel/Gold Dial
Bought this in June 2025, and only wore it a few times. Recently noticed the time was "off" and the seconds-hand wasn't moving. I thought it sat too long and needed to be wound up. So, I wound...and wound...and wound. Never met any resistance in the crown during clock-wise winding...just continued to spin freely, and the seconds-hand never moved. It's a pretty-looking time piece, but don't waste your money if you expect it to keep time. 👎

Great watch, terrible resizing tool.
Color: 2926 Silver Stainless Steel/Black Dial
Watch is great, feel heavy, looks beautiful in person. It shines pretty heavily. My main issue is with the resizing tool it comes with. It broke when I tried to use it. Be prepared to buy your own like I did. I can’t say how the fit is yet because I can’t wear it yet. It is not easy to set up.
