The intersection between constant voltage mode and constant current mode is called the transition point. For example, if the load makes the power supply work in a constant voltage mode, a constant voltage is output. With the increase of load, the output voltage will remain unchanged and the output current will increase. When the current value reaches the set current limit value, the power supply will automatically switch to the constant current mode. The output current remains stable, and the output voltage decreases proportionally with the further increase of load. The conversion between constant voltage and constant current is indicated by the LED on the front panel. 【Start】SPS seriesRemarkable characteristics, product characteristics【High Precision, Low Ripple, LED Display, Auto Switch C.C/C.V Mode】NICE-POWER 30V 10A DC power supply is a professional power supply regulator with high accuracy of 0.01V and 0.001A, low ripple of DC power supply.
