ACPL-C720-000E

ACPL-C720-000E is an isolation amplifier designed for current sensing in electronic power converters in applications including motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external shunt resistor and the resulting analogue voltage drop is sensed by the isolation amplifier. A differential output voltage that is proportional to the current is created on the other side of the optical isolation barrier. It is approved by IEC/EN 60747‑5‑5: VIORM = 1414Vpk, UL 1577: 5000Vrms/1min, CSA. It is used in applications such as current sensing in AC and servo motor drives, solar inverters, wind turbine inverters, industrial process control, data acquisition systems, switching power supply signal isolation, general-purpose analogue signal isolation, traditional current transducer replacements.
