Product Description
LEM ART-B22-D70-SP3 + AI-PMUL Single Phase Rogowski Coil Set, Class 1, User Selectable 0.333v, 0.166v, True RMS 4-20mA, 0-20mA, 0-10V, 0-5V Outputs, Sensitivity, and Measurement Range, 7cm Diameter
The universal Rogowski coil integrator AI-PMUL complements LEM’s flexible clip-around coil ART and ARU range. The design is based on digital processing to give combined dynamic range, accuracy and versatility of use. It offers a wide range of output signals both RMS and instantaneous. AI-PMUL is DIN rail mounted and can be stacked for multiphase application without spacing thanks to its low power dissipation.

- Linearity error ≤ 0.10 %. Protection degree IP2X.
- 35 mm DIN rail mounted.
- Push-in terminals.
- 4 selectable true RMS output signals: 0…20 mA, 4…20 mA, 0…5 V, 0…10 V.
- 2 selectable instantaneous output signals: 225 mV, 333 mV.
- 6 selectable sensitivities depending on Rogowski coil: 22.5, 70, 80, 85, 100, 120 mV/kA at 50 Hz.
- 12 selectable ranges: 100, 200, 300, 400, 500, 600, 800, 1000, 1500, 2000, 4000, 5000 A.

Datasheet
Applicaton Notes
1) The Rogowski coil can measure any primary current as there is no saturation effect.
2) Not tested given that in the worst case (load = 0 Ohm i.e. short circuit on the output) the peak dissipated power remains low (< 2 Watts)
3) Frequency bandwidth and phase shift modelling schematic can be provided on request.
4) Referring to the main phase offset of 90 ° (a Rogowski coil is a derivative current transducer)
5) Considering a primary conductor of at least ⌀ 15 mm, perpendicular and in contact with the Rogowski coil.
6) Considering an external conductor of at least ⌀ 15 mm the same current level than internal conductor, perpendicular and in contact with the Rogowski coil.
