1 Amp Sensitive & Standard Triacs
Lx01Ex & LxNx & Qx01Ex & QxNx Series
Description
1 Amp bi-directional solid state switch series is designed
for AC switching and phase control applications such as
motor speed and temperature modulation controls, lighting
controls, and static switching relays.
Standard
type devices normally operate in Quadrants I & III
triggered from AC line.
