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.
For general applications, the ACNT-H87A (±1% gain tolerance) and the ACNT-H870 (±3% gain tolerance) are recommended. For high precision requirements, the ACNT-H87B (±0.5% gain tolerance) can be used. The ACNT-H87B/H87A/H870 family operates f...
