Constant-current discharging CONSTANT-CURRENT CHARGING/ DISCHARGING OF BATTERY Connect load resistor R as shown Fig. 16. We assume the bat- tery terminal voltage as E and discharging current as I. Constant-current charging It is possible to charge a battery or capacitor automatically with a charging current or a final voltage preset.
MAINTENANCE AND ADJUSTMENT MAINTENANCE Voltage conversion To convert the device to the line voltage, change the power Removal of cases transformer and fuse as noted below. It is not necessary to To remove the case, slacken off the screws on the top and change the fan.
