3. Control Method |
|
Zero Cross Trigger Method
Output TURN ON or TURN OFF only on zero cross point of sine wave,may avoid surge or EMI/RFI occurring.
Specially suited to control resistive,capacitive and Non-saturated inductive loads |
|
|
Variable resistance control method
Power output is controlled by the trigger angle of triac with variable resister 250KQ/110VAC,500KQ/220VAC
