Accu charger with IC LM723C
Circuit of 12 V accu / battery charger with IC LM723C. This Accu charger have input from the first transformer - voltage 220 initially V/110V/240V, the input voltage lowered approximately 12 VAC, then voltage 12 Volts will be rectified by D1 and then filtered by C1 , then filtered and amplified again by IC LM723 and NPN transistor , output voltage is ready to use to charging the accu / battery. Accu charger with IC LM723C Part list : T1 = Transformer , DC 12 V D1 = Diode bridge C1 = 470uF /50V C2 = 1000pF R1 = 4R7 R2 = 5K R3 = 3K9 R4 = 7K5 R5 = 8K2 VR = 2K - 5K trim TR1 = MJ2840 IC = LM723C
