Power supply units harbor dangerous latent electrical energy. High-voltage primary filtering capacitors can hold charges exceeding long after the unit has been disconnected from its source. Always discharge the bulk input capacitors safely through a high-wattage resistor before testing components, probing lines, or reworking solder pads on the PCB. While a schematic is a luxury, many common

The Wannien 101V0 is a compact switching power supply module commonly used in small consumer electronics. This article outlines a typical power supply schematic for the 101V0 family, explains each block’s function, and provides troubleshooting and modification notes. Always discharge the bulk input capacitors safely through

If the output is not a stable 5V, the main voltage regulator IC may be damaged.
