Function features

◆ It has main, average and floating charge selection and the voltage can be regulated and has the fucntino of stabilizing voltage and limiting current
selection
◆ Computer monitoring unit adopts large screen LED display with such series data as cell voltage charging voltage , bus voltage , output voltage and
current of battery charger ,voltage and current of singl piece of battery ect.
◆ Reopertion after loss of AC and the sytem can charge the battery in the best way as per battery’s capacity. After removal operation of the computer
normal operation of DC system is not affected.
