ACPL-C87A-000E

The ACPL-C87A-000E is a precision optically isolated Voltage Sensor, designed specifically for voltage sensing. Its 2V input range and high 1GΩ 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. The high common-mode transient immunity (15kV/us) of this provides the precision and stability needed to accurately monitor DC-link voltage in high noise environments. Combined with superior optical coupling technology, this implements sigma-delta modulation, chopper stabilized amplifiers.
