Hello,
I know that MOC3052M is designed as triac driver, but I have to drive a small load of 10mA and I tried to drive it directlly from MOC, without using the second triac, as sugested in datasheet.
It is working without any problem. I limit the current trough triac as a double safety measure with a 680Ohm series resistor.
With or without the resistor, circuit work just fine.
Load sinks about 100mA inrush, stabilize after about 10sec to 20mA and stays at 10mA after about 3 minutes.
I attached the schematic, first channel is designed according to MOC datasheet, the others are the ones I am wondering if they are working or not.
Is it a problem to use the opto-triac to drive directlly the load? Do you recommend to keep the series resistor?
If I cannot use it this way, do you know why it cannot be used?
Thank you!
