LEM AI-PMUL Universal Integrator for Rogowski Coils, Multi Range Input (100 to 5000 Amp) and Output (0.333V,0.225), and True RMS outputs (4-20mA,0-20mA,0-5V,0-10V), Adjustable Sensitivity(22.5,70,80,85,100,120mV/kA), Din Rail Mount 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 True RMS and instantaneous. AI-PMUL is DIN rail mounted and can be stacked for multiphase application without spacing thanks to its low power dissipation. optional Input signal Accuracy Class 0.5 (IEC 61869-2) [1]. 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.
