Altech Silicon Controlled Rectifier (SCR) /IGBT type battery chargers regulate charging current by allowing the battery to determine its own charge cycle rate in accordance with its state of discharge. SCR chargers provide a constant current-constant voltage-constant current (I-E-I) charge that eliminates the possibility of overcharging, even with line voltage variations of +/- 10%, and allows the battery to finish at the proper current, regardless of its age or temperature. Altech battery charger range starts from 12 VDV - 384 VDC ......
