The E-652A is a precision current transducer that performs true RMS current measurements in one AC circuit wired through an interfacing CT mounted on the top of the enclosure.

The E-652A may be ordered for various current ranges. The 0-5A and 0-10A current ranges feature a very high accuracy CT providing 0.3% accuracy (full scale). Other standard ranges include 30A, 50A and 100A. The 5A calibrated i-SnailÔ-A can be applied to the secondary wire of a 5A CT thus extending the metering range as required.

The E-652A is powered from the 4 -20 mA current loop (it acts as a ‘two wire loop device’). It will accept a wide range of loop excitation voltages, typically 24 VDC. The unit is hermetically potted in a small plastic enclosure equipped with two mounting holes. A barrier strip terminal is provided for the output wiring.

The E-652A does not include a built in CT and is equipped with spade connectors allowing remote installation of various Elkor miniature CTs (MCTA and MSCT).
