 		 #81883 - Loading is enough.
Responding to: ???'s previous message
Dear Russell, Thanks for your kinmd support.

Can you rule out that the flickering is not caused by an insufficient load? Thyristors have a minimum hold current, go below this and they WILL flicker.


Yes, I can completely rule out the fact that flickering is not due to improper loading of thyristor. I am using our standard test insrument with 100W lamps. This instrument can detect all sort of thryristor firing problems including half firing.

Thanks & Regards,
Prahlad Purohit

      Why not use the PCA?            01/01/70 00:00      
         It's too late to change the design.            01/01/70 00:00      
   Its not a interrupt priority problem.            01/01/70 00:00
