2. V- (Negative Output)
Pin: 2
Description: The negative output pin provides the return path for the 12V DC output of the power supply.
Connection: Connect to the negative terminal of the load (device being powered).
3. AC_IN (Live/Hot Wire)
Pin: 3
Description: The AC input pin connects to the live/hot wire of the AC power source.
Connection: Connect to the live/hot wire of the AC power source (e.g., wall outlet).
4. AC_IN (Neutral Wire)
Pin: 4
Description: The AC input pin connects to the neutral wire of the AC power source.
