Details
Tips:
DC power supply generally has multiple outputs: For example, one fixed output is 5V, 2A, two adjustable outputs (CH1, CH2) are 0-30V, 0-5A. The adjustable output generally has two working modes of constant voltage and constant current. These two working modes are automatically converted with the change of load. The LED on the front panel of the instrument shows the CV and CC modes, the green light shows the CV (constant voltage) and the red light shows the CC (constant current). Some regulated power supplies also provide CH1 and CH2 series operation and master-slave tracking mode. If CH1 circuit is the main circuit and CH2 circuit is the slave circuit, the output voltage of the slave circuit will change with the main circuit when tracking the working mode, which is more suitable for occasions requiring symmetrical bipolar power supply. If CH1 and CH2 are connected in series, 0-60V and 0-5A DC power supply can be output. In series tracking mode, 0-±30V and 0-5A DC power supply can be output.
