I design a board with 3 triac output.
The power supply is 220VAC and i want to give 150VAC to a load.
The load i a switching AC/DC load with power max cons. 40VA.
I detect zero cross and i trigger the MOC for 1ms only.
The problem is that after some times a triac is "burned".
I am using the below curcuit.
Can you help me?
