The IUC-7X-RMS-XXY is a microprocessor controlled RMS converter. It comes in a DC and in an AC configuration for either current or voltage measurement. In the DC configuration, the instrument computes the RMS value of both the DC and the AC component of the input signal. In the AC configuration, the input is capacitively coupled so that the DC component is blocked and only the AC component is used to determine the RMS value.

Both configurations sample the input waveform 2500 times to compute the the true RMS value. This ensures great accuracy and allows for accurate RMS value measurement of odd shaped waveforms. The output is updated every 0.625 seconds

CAUTION: When using AC current we recommend using the ACI-CT current transformer for dangerous over-voltage protection.
