ACPL-C72B-000E

ACPL-C72B-000E is a precision miniature 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 Motor phase and rail current sensing, servo drives and motors, power inverter current sensing, industrial process control, data acquisition systems, general purpose current sensing, traditional current transducer replacements.
