in this video number {761} SMPS Is Not Working || SMPS Not Turning ON, it is Panasonic fax machine KX-63BX, KX-63BX-W, its power supply model number PFLP1282EZL, SRF1018EK SMPS Output voltage Fluctuation / Switch Mode Power Supply Output Not Regulated. it is using KA7552 PWM controller ic, it have 24 volt and 5 volt outputs #howtorepair #smps #panasonic SMPS Output voltage Fluctuation / Switch Mode Power Supply Output Not Regulated. smps output fluctuation term is used when the output voltage of switch mode power supply are not being regulated properly. irregulated amplitude of the output in any smps is called fluctuation it may be due to many reasons 1. main dc capacitor is internally open circuit 2. vcc capacitor of smps ic is open internally 3. vcc circuit / bias circuit / auxiliary circuit is open circuit 4. output circuit have some short circuit capacitor 5. feedback circuit is not working properly, it may be due to reference circuit, TL431 reference, or optocoupler or its related components SMPS practical tutorial    • SMPS Switching switch Mode Power Supp...   SMPS Is Not Working, smps not turning on, smps is not working how will you check, how to check smps is working or not, smps, how to repair smps, how to repair, switch mode power supply, haseeb electronics, switching mode power supply tutorial, switching mode regulator, switching mode power supply, smps tutorial, how smps work, very easy repair of smps, smps repair, switching power supply repair, smps repair step by step, smps no output voltage, SMPS Output voltage Fluctuation, Switch Mode Power Supply Output Not Regulated, how to repair switch mode power supply, output fluctuating, reasons for smps output voltage fluctuation, switch mode power supply output fluctuating, why smps fluctuates, fluctuated or unregulated output, how to repair switching mode power supply, smps output fluctuating, basics of switching mode power supply, how switching mode power supply works, basic working of switching mode power supply, how to repair switch mode power supplies, smps output voltage low, smps basics, smps feedback circuit, reasons for smps fluctuation, smps have low output voltage, laptop charger repair, how to find short circuit in smps, how to repair smps power supply, chowk azam, smps output voltage fluctuation, feedback in switching mode power supply, amps explained, how switching power supply works, how smps works, repair, troubleshooting, how to know if smps is not working, power supply 00:00 repairing panasonic fax machine power supply 00:21 how to power up a circuit for testing in lab 01:10 how to measure voltage in panasonic power supply board SRF1018EK 01:30 smps low output with output fluctuation 01:52 main dc smoothing, bulk capacitor have fluctuation 02:02 how to check vcc voltage of SMPS pwm controller IC 02:21 how to test voltage on MOSFET 02:41 how to find short circuit in smps secondary side
