A once popular power supply, the "XiaoShangdi" teacher's classic power supply adjustable constant current 0-35V 0-5A.
Do it again in a few years, huh, this time is a double panel.
1. Time-consuming and effortless double-sided full-line PCB: 10*10CM
2. Turn over the cabinet, add the disassemble and purchase, and finally get the components together:
The cable is also readily available for external components.
3. Use a power supply main control board that has been soldered for one afternoon: 0-30V
(I only have a dual 12V transformer, one winding less than the drawing design)
4, right, there are still close-ups of the 1602 header:
5. Connect and install all the peripheral accessories except the case, the next step is to debug:
6. Stay away from the board and worry about the power, although I think it is very careful.
One of the 470uF electrolysis still exploded (the polarity is reversed),
After adjustment and replacement, try it, 0-30V adjustable, basically normal use! Oh, success,
The test data of each indicator is to be continued. . . . . The 1602 meter performance is also to be tested. . . . .
7. Attach the original original picture of Teacher XiaoShangdi:
8. I believe that many of the power friends have done this, there are many posts on the Internet to make this power.
Please also give me some pointers, thank you,
