{290} Why Isolated SMPS Output have Live Line Voltage - SMPS Output Gives Electrical Shock Urdu

in this video i discussed Why Isolated SMPS Output Contains Line Voltage - SMPS Output Gives Electrical Shock. i explained in urdu hindi language. tester glows in dc supply of isolated switch mode power supply (SMPS). in isolated smps, the output must be isolated from line and neutral input. but in some reasons some line component enters in secondary output and while touching the output it gives electrical shock. and if we touch tester to output, the neon inside the tester glows, it indicates that there are live line voltage in output section, it may be due to class y rated capacitor, mosfet mounting tab or insulator leakage, smps transformer inter winding insulation leakage. or winding short circuit between primary winding & secondary winding tester glows in output of switch mode power supply tester glows in neutral, tester glows in earth or chassis of the switch mode power supply tester glows in dc supply, basics of switching mode power supply, smps tutorial how to repair switching mode power supply how to find short circuit in smps how to repair smps power supply smps repair step by step smps working basics haseeb electronics chowk azam
