8 Channel Opto Triac Driver Circuit
The driver circuit 220v working with devices or lamps used to control the opto isolators to (moc3020, moc3040 available) provided Signals based on triacs (bt138, bt139 available) transmission is going triac placement of small type cooler made but the power drawn and the working time according to the coolant may not be used already flexible in-circuit power triac triac power varies depending on the way to the cooler part of screwing the middle leg that is associated with that portion when working through the voltage insulators come in contact with the cooler mount
