Hi all, I want to use MOC3023 with triac for phase angle control using arduino and I am having hard time to trigger the triac with this optocoupler the schematic is attached (the input is pulses from arduino) and the applied voltage is about 100Vrms is there something I doing wrong or either optocoupler or triac has an issue ? |
| Benta:
Where are the gate resistor(s)? Also, can an Arduino deliver the 5 mA needed to trigger the device? |
| wraper:
Your circuit is incorrect. It looks somewhat like SCR circuit but gates and optocoupler are connected wrong. |
