{294} Make Variable Power Supply - Increasing Computer ATX Power Supply Output Voltage

Make Variable Power Supply by Increasing Computer ATX Power Supply Output Voltage. Convert ATX PSU Into Variable Power Supply, Increase ATX Output Voltage. in this video i demonstrated how to make adjustable / variable power supply from computer atx power supply / PSU to make benchtop / workbench power supply OR you can use as 12V car battery charger OR for dc motor based room cooler / desert room cooler or many other projects and applications. Computer ATX Power Supply can be hacked to convert it in very simple steps. #convert #atx #psu first disable the overvoltage, undervoltage, overcurrent, short circuit protection by disabling atx supervisor IC or LM339 or any comparator or operation amplifier IC working as ATX housekeeping function. ATX Bench Power Supply - Convert a Computer Power Supply Converting Computer ATX Power Supply to Lab Bench Power Supply How To Disable Voltage & Current Protection from ATX PSU. i demonstrated TL494 / KA7500 based atx psu, it is using LM339 comparator ic. this works as ATX supervisor ic for housekeeping and monitoring all the atx function and it turns off TL494 /KA7500 in any abnormal case (over voltage, under voltage, short circuit, over current ) it will pull up pin 4 of the TL494/KA7500 that is dead-time control pin when this pin is pulled up above 2 volt, it shutdown the ATX and disables the SMPS controller option it prevent the atx operation by auto shutdown from under voltage, overvoltage and overcurrent conditions. so you can modify/ Disable short circuit and overload Computer ATX Power Supply into car battery charger or lab power supply for your electronics workbench or you can make it variable dc power supply. How To Disable Voltage & Current Protection from ATX PSU / computer power supply atx power supply variable voltage, modify computer / server / atx power into adjustable / variable bench supply to use as bench power supply, car battery charger atx power supply conversion variable power supply diy, haseeb electronics atx power supply repair, atx power supply conversion, How To Disable Voltage & Current Protection from ATX PSU / computer power supply server / pc/ computer power supply / atx psu hack How to Modify / Disable short circuit and overload protection in ATX power supply protection in ATX power supply modify atx power supply variable voltage
