The Elite ECO model CBHD3 is a high frequency battery charger suitable in a wide range of applications for recharging deep cycle flooded, gel and agm batteries. Power conversion is done with IGBTs in a push-pull circuit and power factor correction resulting in an electrical efficiency greater than 90% in a compact package. Both current and voltage output are finely controlled regardless of AC input. Users can select from 4 different pre-programmed charging curves to suit a variety of lead-acid battery brands and types.
