on video I Turned Dead SMPS into Variable Lab Bench Power supply


 I Turned Dead SMPS into Variable Lab Bench Power supply

Increase ATX power supply output voltage, convert computer power supply to variable power supply. in this video i showed how to make an adjustable/variable power supply from a computer atx power supply to make a tabletop power supply, carb battery charger, for a current motor room cooler continuous, a desert room cooler or many other projects and applications

Computer ATX Power Supply Hacked to build an adjustable bench power supply. so following these instructions to convert atx computer power supply so you can use workbench power supply or you can build a 12V car battery charger using this atx computer power supply how to build a power supply 12 volt,

ATX Bench Power Supply - Convert Computer Power Supply

Convert computer ATX power supply to lab bench power supply

How to disable ATX power supply voltage and current protection.

I demonstrated the atx psu based on TL494/KA7500, it uses LM339 comparator ic. it works as an ATX supervisor ic for housekeeping and monitoring all atx functions and it shuts down TL494/KA7500 in all abnormal cases (over voltage, under voltage, short circuit, over current) it will pull pin 4 of the TL494/KA7500 which is the timeout control pin when this pin is pulled above 2 volts it shuts down the ATX and disables the SMPS controller option

without disabling Remove short circuit protection, it prevents atx operation by automatically shutting down under voltage, over voltage and over current conditions. So you can change/disable the short circuit and overload computer ATX power supply into car battery charger or lab power supply for your electronic workbench or you can make it DC variable. How to disable voltage and current protection of ATX PSU/computer power supply

This tutorial is part 1 to modify the atx power supply to a bench power supply/battery charger

using this atx power supply we can adjust the voltage to 13.4v to charge 12v car battery or it can be modified as lab bench power supply
