capacitive power supply
Hi guys,
I used this capacitive power supply to run some LED from 240VAC.
R1=2W10R Metal Oxide Resistor
C1=1.5uf 450VAC(x2 Type)
C2=220uf 35V
D1=24V
D2=1N4007
The output around 35VDC. Everything running smoothly. But when I switched off the main 240VAC, there is still around 250VDC inside C1 & I get electric short. How do I discharge C1?
Pls help. Thanks in advance.[/img]
