Adjustable symmetrical 1 to 24V DC/1A power supply circuit diagram

This is the circuit diagram of an adjustable symmetrical 1 to 24VDC, 1A power supply. This power supply provides dual output positive and negative outputs, you can adjust the positive and negative outputs (+1 to +24VDC and -1 to -24VDC). This power supply is also called a bipolar power supply or a split power supply, providing positive and negative outputs.

This power supply can be used universally and requires no more than 1A of DC current. Please note that before using this power supply, you should adjust the output voltage with a general-purpose multimeter or DC voltmeter to protect the equipment provided.
