Description
The KMOC3041
、
KMOC3042
、
KMOC3043
series consist of a GaAs infrared emitting diode
optically coupled to a monolithic silicon detector
performing the function of a zero voltage crossing
bilateral TRIAC driver. They are designed for use
with a TRIAC in the interface of logic systems to
equipment powered from 115 VAC lines, such as
solid-state
relays,
industrial
controls,
motors,
