Abasic home battery charger incorporates a transformer and rectifier, to change the mains 110/220 volt alternating current to 12 volt direct current, and allows the mains supply to provide a charging current at a rate determined by the state of the battery. In the case of a battery in good condition, the rate of charge may be around 3 to 6 amps with a normal home charger. Itcan deliver DC (1-30V) and up to 10A current depends on your input power source, in my case I'm using DC 12V 3A input power source. I easily get continuously adjustable output voltage (1-30V) and current (0-6A), which is pretty enough for circuit testing and other things.I'm also using 7805 voltage regulator IC for 5V constant voltage and Compare StarTech SVA5N3NEUA Replacement 5V DC Power Adapter - 5 Volts, 3 Amps. $ 31.07 (2 Offers) Free Shipping.

It outputs about 17V DC voltage and a max current of about 1.5A. Normally a 1A transformer should use a C1-2,200μF capacitor. But adding one more C2-1000μF capacitor, it will make the DC voltage even smoother. When we intend to use this circuit to test various electronic circuits. tCTXN4T.

can i use 12v 1a for 12v 2a
