MOST SMPS HAVE A RESISTOR TO DRAIN THE CHARGE IN THE MAIN FILTER CAPACITOR
BUT THE RESISTOR MAY FAIL AND THE CAPACITOR CAN HOLD THIS CHARGE EVEN YOU HAVE TURNED OFF THE DEVICE
THIS CAPACITOR HAS ABOUT 330uf AT 400V
TO DICHARGE THIS CAPACITOR
- TURN OFF YOUR DEVICE
- PLACE A RESISTOR ACROSS THE TWO LEGS
- CHOOSE THE RESISTOR LIKE ( FROM 2.2 TO 4.7 K ohm 10watt )
- each time check the charge of the capacitor using your meter
thank you
