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 and vehicles which have an intermittent demand for battery power.

These chargers are housed in a rugged, black anodized aluminum, heat-sink case which extracts heat without introducing dust & moisture to the inside of the unit. The rugged and reliable ABC charger has been manufactured by NEWMAR for more than 25 years, and is employed in hostile environments throughout the world; in mining equipment, emergency service vehicles, off-shore platforms and commercial marine applications. All ABC chargers feature a total output ammeter, on-off power switch, power "on" indicator light, 115/230 VAC input voltage selector switch, factory installed AC power cord with molded plug and shock-resistant rubber mounting grommets. Circuit boards are polyurethane conformal coated for corrosion resistance and all are protected against overheating by an automatically resetting thermal switch.
