LM317

Here comes very simple idea is the universal battery charger circuit. When, an input power is applied to the circuit. The SCR1 (Silicon controlled rectifier) turn off, then not has a bias current path to ground. The LM317 acts as a current regulator, It is connected to the battery thought a one way diode D1, [...]

This is circuit Automatic Charger and Full charged indicator. For 24V batteries it can charger with current be stable about 1.5A and have voltage output 27Volt with integrated number circuit LM317K. When the battery has had full already , as a result will cut the work. There is a tube LED show the work with [...]

This circuit is DC converter low voltage , 12V from be 1.25V to 10Vdc by can give current topmost get about 1.5A. You should use IC number LM317K because have electric many power more the number LM317T. By should hold heat sink. That have large-sized with. The R4 use for fine decorate voltage output. The [...]
