INTEGRATORS FOR ROGOWSKI COILS
LEM Integrators and accessories for Rogowski Coil current sensors
MULTI-OUTPUT DIGITAL ROGOWSKI INTEGRATORS
LEM provides several Rogowski coil integrators to complement its flexible clip-around coils ART, ARU and ARH series.
The AI-PMUL Rogowski coil integrator design is based on digital processors to give combined dynamic range, accuracy, and versatility of use. It offers a wide range of voltage output signals both RMS and instantaneous.
AI-P1A Rogowski coil signal conditioner provides a 1 A output instantaneous signal to replace conventional current transformer with dynamic extended range.
AI-P1A and AI-PMUL can be installed on a DIN-rail close to each other without losing any space. Moreover one power supply can be used for three devices connected each other.
INTEGRATOR AI-PMUL SERIES
Main characteristics & benefits
