LEM LA 100-P is a high-quality current transducer that provides precise measurement of DC, AC, pulsed, and mixed currents. It features high accuracy, excellent linearity, low temperature drift, and a wide bandwidth. With its fast response time and high resistance to electromagnetic interference, it is perfect for demanding industrial applications.

The device has galvanic isolation between the primary and secondary circuits, ensuring additional safety and insulation. LEM LA 100-P is used in variable speed AC drives, servo motor drives, DC motor converters, battery power supplies, UPS, SMPS, and welding systems.

Main features

  • Closed-loop (compensated) current transducer using the Hall effect
  • Insulated plastic housing compliant with UL 94-V0
  • Excellent accuracy
  • Very good linearity
  • Low temperature drift
  • Optimized response time
  • Wide bandwidth
  • No insertion losses
  • High immunity to external interference
  • Overcurrent capability

Applications

  • Variable speed AC drives and servo motors
  • Static converters for DC motor drives
  • Battery-powered applications
  • Uninterruptible power supplies (UPS)
  • Switched-mode power supplies (SMPS)
  • Power supplies for welding applications
