PS303DFPower upBack sidePackagedPackaged




PS series power supply is a kind of continuously adjustable linear DC voltage regulator power supply with high stability, high reliability and low noise. Its output voltage and current can be continuously adjusted. Also it can be both as constant voltage and constant current dc power supply. Its constant voltage and current can be auto-conversion. This low cost and universal power supply can be used in many different areas, from production lines to school use.
