Basic Functions Of DC Power Supply

DC stabilized power supplies generally have multiple outputs: for example, one fixed output is provided as 5V, 2A; two channels (A and B) are provided with adjustable outputs of 0～24V, 0～1A. Adjustable output generally has two working modes: voltage stabilization and current stabilization. These two working modes are automatically converted as the load changes. The light-emitting diodes on the front panel of the instrument display the CV and CC modes. Generally, the green light indicates CV ( Voltage regulation), red light means CC (steady current). Some stabilized power supplies also provide both A and B serial work and master-slave tracking work. If the A road is the main circuit and the B road is the slave circuit, the output voltage of the slave circuit changes with the main circuit in the tracking mode. This is more suitable for occasions that require a symmetrical bipolar power supply. If A and B are connected in series, they can output 0～48V, 0～1A DC power; in series tracking mode, they can output 0～±24V, 0～1A DC power.
