View Full Version : Fired Resistors

I'm using ssroz in 220V and i'm having some troubles with the resistors between the triac and the optocoupler. The resistors are getting fired every day in the same SSR board in the same light. I only have this problem with short led tube lights. I've checked if there was a short-circuit with the led tube and it seems to be ok.
I thought that maybe the resistor is to small for 220 and it should be bigger for the short led tubes.

PS: adding a dumy load would solve the problem?

check the solder joints on your triac.

i don't find anything wrong with the solder joints on the triacs. They seem to be ok
