The ABC Series chargers utilize time tested SCR charging circuitry, individually sensing and regulating each of 2 isolated battery banks, allowing the user to leave the charger operating indefinitely, even under no-load conditions without fear of overcharging. These chargers are ideal for vessels or vehicles which have an intermittent demand for battery power.

These chargers are housed in a rugged, powder coated aluminum, heat-sink case which extracts heat without introducing dust and moisture to the inside of the unit.

The rugged and reliable ABC charger is employed in hostile environments throughout the world in recreation and commercial marine applications, off-shore oil platforms, in mining equipment, emergency service vehicles and rugged off-road applications.

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-vibe applications. It is available to fit all NEWMAR units from 2 to 70 lbs. Specify KIT-L for units which weigh 2-15 lbs. and Kit-H for units which weigh 16-70 lbs.
