The Elite Series of high frequency battery chargers are switch mode chargers with high frequency transformers, IGBTs and digital controls. Both current and voltage output are finely controlled regardless of AC input. Low output ripple makes them ideal for sealed batteries. Users can select from among 11 different pre-programmed charging curves for all types of lead-acid batteries whether they are flooded, gel or agm. During recharge, status can be viewed on the display including current, voltage, recharge time, Ah capacity and kWh returned to the batteries.
