Iterate a bit - for 10,000uF, we'd let the caps down in about 20 seconds, om 60 Volts. Yes, that's a useful period to get the caps discharged. What Kaz needs, namely 1sec, would need a 50R resistance, or so, with a heat dissipation of 11.5W (24V assumed). So, at least a 20W resistor should be used, not mentioning the additional current drawn from transformer... Well, not a very good idea, unless he cannot solve the problem differently. Kai |
