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).

  • Input: Wire current input through CT up to calibrated range:
    0-10A AC
    0-25A AC
    0-50A AC
    CT Wire Window: 14.5mm (0.570”)
    Frequency: 50 or 60 Hz
  • Output: 1% of full scale.
  • Accuracy: TRMS, 0.3% FS for 0-5A & 0-10A ranges, 0.5% for other ranges.

The E-652V is a simple self power AC current transducer that provides a 0-5V analog signal proportional to the AC current flowing through the CT. Available in three ranges, the i-SnailÔ-V is calibrated to AC sine wave. There is no need for input current configuration nor trimming, saving time and confusion in the field.

The transducer is enclosed in a fire retardant ABS box and encased in potting epoxy to withstand moisture, dust and vibration. The integrated mounting tabs provide an easy means to install the unit on a wall or within a control panel.

The E-652V is ideal for load monitoring without the need for an external power supply. Two signal wires are all that are needed to obtain a linear, 0 to 5 V DC output voltage that may be easily interfaced with PLCs and DDC SCADA systems.

The E-652V includes an on-board CT with a 14.5mm (0.570”) wire window that can accommodate up to AWG #2. The available input ranges are 0-10A, 0-25A and 0-50A. Multiple turns of the primary wire may be used to alter the input range.
