ACNT-H87B Datasheet Precision Optically Isolated Voltage Sensor

Manufacturer: Broadcom

General 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.
