Phase control up to 40A with TRIAC and DIAC (Optocoupler)

WebAs the supply voltage increases in either a positive or negative direction, it reaches the minimum value required to turn the output thyristors or triac fully ON (usually less than about 15 volts). The voltage drop across the SSR’s output terminals is that of the switching devices on-state voltage drop, V T (usually less than 2 volts). WebTriac can last/work millions of cycles, and it is silent. So: when you need a silent and frequently working output, you should choose triac.
