This is circuit variable voltage regulator power supply. It use IC L200 ( good ic regulator) Out voltage 3V to 15V and Current 2A . By Transformer 2A 12V. Detail more see to circuit.
Using the versatile L200 voltage regulator, this power supply has independent voltage and current limits. The mains transformer has a 12volt, 2 amp rated secondary, the primary winding should equal the electricity supply in your country, which is 240V here in the UK. The 10k control is adjusts voltage output from about 3 to 15 volts, and the 47 ohm control is the current limit. This is 10mA minimum and 2 amp maximum. Reaching the current limit will reduce the output voltage to zero.
