(1) output voltage: range 0 ~+9.9 V, step 0.1V, ripple less than 10mV. (2) output current: 500mA. (3) The output voltage from the digital display. (4) from " +" ," -" two keys control the output voltage step increase or decrease, respectively. (5) To achieve the above a few parts of the work, made a regulated DC power supply, output Output ± 15v,+5 v. (6) Self-acceptance program: the realization that the basic functions.
