The requirements for leakage current protection in the American standard (UL2231) are very different from those in the national standard (GB/T 18487.1) and the European standard (IEC61851, IEC62752 and IEC62955). This time, let's take a brief look at the requirements for leakage current protection in the American standard (UL2231).
Why does IC-CPD need a built-in RCMU to detect DC leakage?

During the charging or starting process, IC-CPD is required to complete the self-check function, automatically initialize the self-test, and check whether all its functions including the residual current are normal. If there is an abnormality, charging should not be started. Leakage current detection rcmu is a key detection content of IC-CPD.
