Additional Details:

The ACPL-T350-560ME uses sigma-delta modulation and chopper-stabilized amplifiers to achieve high accuracy and stability over temperature. It supports a wide range of input voltages and currents, making it suitable for a variety of power conversion applications. The device typically requires a 5V power supply on the output side. The high CMTI ensures that the amplifier is not affected by fast-switching transients, which are common in power electronic circuits. It finds common use in applications demanding high levels of isolation and precise measurements in noisy environments. It conforms to safety standards like IEC/EN/DIN EN 60747-5-5.
