ACNT-H87B, ACNT-H87A, ACNT-H870 Precision Optically Isolated Voltage Sensor in a 15-mm Stretched SO-8 Package Data Sheet Description The ACNT-H87B/H87A/H870 voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2-V input range and high 1-G input impe-dance, 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.
