The Panasonic APT1231 is an optocoupler with Triac and SCR outputs, which works with a phototriac. It is used to provide an isolated connection between an AC line voltage and a DC controlled signal, allowing for the efficient control of an electrical current. It has a dielectric strength of 10kV, making it suitable for high voltage applications. It also has a low resistance and can operate at temperatures up to 110 °C. This optocoupler is also UL recognised and RoHS compliant. It is suitable for use in a wide range of applications, such as motors, dimmers, remote controls and many others.
