L200 Figure 26. High Input and Output Voltage. Figure 27. Constant Current Battery Charger.
The resistors R1 and R2 determine the final charging volt- age and RSC the initial charging current. D1 prevents dis- charge of the battery throught the regulator. The resistor RL limits the reverse currents through ther regulator (which should be 100 mA max) when the bat- tery is accidentally reverse connected. If RL is in series with a bulb of 12 V/50 mA rating this will indicate incor- rect connection.
