低功耗、多功能输出型积分器
用于罗戈斯基的LEM集成器
MULTI-OUTPUT DIGITAL ROGOWSKI INTEGRATORS
LEM provides several Rogowski coil integrators to complement its flexible clip-around coils ART and ARU families.
The AI-PMUL Rogowski coil integrator 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 can be stacked for multiphase application without spacing.
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 stacked up to 3 Integrator modules and use only one power supply for multiphase application without spacing.
Both LEM integrators for Rogowski Coils are DIN rail mounted.
