LP-IRMS RMS Responding Current Transducer

The LP-IRMS current transducer converts an ac current input into a dc output signal which is proportional to the rms of the input.
The root mean square measurement of the input signal allows accurate measurement of distorted waveforms.
Power for the unit is derived from an external supply.

Ordering information: LP-IRMS, input, output, power supply.
Example: LP-IRMS, input 0-1A, output 0-10mA, supply 110Vdc.
