OptoCoupler 1-CH 8-Pin SO Tube

The ACPL-C87A voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2 V input range and high 1 G? input impedance, makes it well suited for isolated voltage sensing requirements in electronic power converters applications including motor drives and renewable energy systems. In a typical voltage sensing implementation, a resistive voltage divider is used to scale the DC-link voltage to suit the input range of the voltage sensor. A differential output voltage that is proportional to the input voltage is created on the other side of the optical isolation barrier.
