Accurately everywhere
Closed Loop Hall effect current transducers performing at the level of Fluxgate technology without the added cost


Main characteristics:

 

  • DC, AC and pulse currents measurements with galvanic isolation
  • Current measurements from 1.5 to 50 ARMS nominal (6A, 15A, 25A and 50A models)
  • 22 multi-range models for 6 families
  • Low offset drift between 4 to 14 ppm/°C
  • Attractive price
  • PCB mounting in various footprints (3 or 4 primary pins with various layouts)
  • With aperture and/or integrated primary conductors
  • 5 years warranty
  • Compact design
  • High overall accuracy at +105°C up to 2%

 


Features:

  • Single supply 0, +5 V
  • Isolation test voltage: up to 4.3KVRMS / 50 Hz / 1 min
  • Closed Loop Hall effect technology based on a LEM specific proprietary ASIC
  • Operating temperature range: -40°C to +85°C...+ 105°C
  • Voltage output
  • Fast response time <0.4 µs
  • LXSR & LESR & LKSR & LPSR: Reference access on additional pin
  • LPSR & LKSR: Different primary footprint with 4 pins for higher creepage and clearance distances (9.9 mm) for higher insulation
  • LPSR: Overcurrent detection output included
  • LXS & LXSR: Primary integrated conductors + aperture

 

 

Standard compliance:

 

  • Industrial standards for applications such as:
    • Home appliances
    • Solar inverters (AC output)
    • Servo motor drives
    • Variable speed drives
    • Robotic
    • UPS
    • SMPS
    • Static converters for DC motor drives
    • Air-conditioning
    • Power suppliers (welding)
    • Battery-supply applications

 

Remarks:

  • Each model is multi-range according to primary connection configuration
  • Bipolar currents measurements when single supplied 0/+5V
  • 100% fully compatible vs LEM LTS - LTSR - CAS - CASR - CKSR models (previous generation)
