How to connect the universal power supply module

In my last post I talked about a universal power supply that's gaining ground on my area. I laid my hand on it and had used it to repair some power supplies that would have been rendered useless. One of such power is that used in a double door refrigerator

To connect the module,neglect the green wire.connect the black wire to the negative terminal of the electrolytic capacitor (400v100uf).For the red wire do not connect to the positive of 400v100uf that's where some people get it wrong but instead as shown in the picture below connect to the other positive terminal on the sm transformer that linked to the power ic or power transistor depending on the type of power supply you want to repair but remember to cut the terminal away from the board



Before switching on reduced the output of the power supply through the variable resistor on it so after switching on you can increase to your desired valued this is to prevent the main board from damage due to excessive voltage.

Recommended:universal power supply that can be useful as replacement in electronics gadgets selling hot on Konga
