funcTions:
• WSC720 must be connected to the battery as described in the
User Guide. After it is connected, it will charge the battery and
maintain it fully charged with constant voltage charging (float
charge) as long as it is connected to the mains power.
• Don’t keep WSC720 connected to the battery without mains
connected. This will in the long term discharge the battery.
• WSC720 is fully automatic and is programmed for advanced
charging of lead-acid batteries between 40 and 500 Ah.
• If the 24 V mode is selected, the battery voltage must be higher
than 15.8 V. If not, the red LED will indicate a fault.
• Security functions will reduce over charging, by terminating the
charge, especially if the batteries are larger than 500 Ah.
• WSC720 can be used as a Power Supply by pressing the
”Mode” button to 13.7 V Power Supply. In this mode WSC720
will provide a voltage of 13.7 V and max. 70 A.
• ”13.7 V Power Supply is to be used for Power Supply in 12 V
electrical systems and for continuous charging, float charge, of
12 V batteries.
• For maintaining voltage in 24 V systems, Mode “24 V charging”
shall be used.
• WSC720 is equipped with temperature compensation. The
thermal sensor is integrated in the negative, black, terminal
clamp.
• Thanks to our temperature compensation, the common
problems involved in insufficient charging in cold weather and
overcharging at high temperatures are eliminated.
• The charging curve consists of five steps that are adapted to
battery technology.
• In order to minimize the risk of overcharging an incorrect type
of battery, WSC720 is equipped with a cut-out function that
interrupts the process after 7 h and the fault is shown by the
LED shining a constant red. NOTE: This alarm can be triggered
when charging batteries that have capacities exceeding
the recommended battery size, or in connection with other
