Re: 12V 2A battery charger/maintainer
Hi,
There is a resistor R15 = 2k2, located next to the transformer. If you increase the resistance value a bit, then you will lower down the output voltage. Try to replace this resistor to 2k7, and measure the output voltage, it will be drop to about 12V.
Or you can replace it with a potentiometer, ranging around 2-3 kilo Ohms, then you can tune the output voltage...Leave a comment:
