RAPID BATTERY CHARGER FOR ICOM IC 2A


Posted on Feb 4, 2014

Rectifted and filtered voltage from the 24 Vac transformer is applied to the LM723 voltage regulator and the npn pass transistor set up for constant current supply. The 470 ohm resistor limits trickle current until the momentary pushbutton (S2) is depressed, the SCR turns on and current ftows through the previously determined resistor network limi
