LH_FAMILY

High accurate current measurement from 8 up to 100 ARMS for PCB mounting


Main characteristics:

  • PCB mounting design for 8 to 100 ARMS nominal current measurements
  • Exceptional overall accuracy up to 0.5% of IPN over the temperature range
  • Maximum offset drift of up to 0.1% of IPN
  • Fast response time less than 0.5 µs
  • Compact design
  • 5 years warranty

Features:

  • DC, AC pulse currents' measurements with galvanic isolation
  • Dual supply +/- 12 to +/- 15 V
  • Isolation test voltage: 5 kVRMS / 50 Hz / 1min
  • Current output
  • Operating temperature range: -40°C to +85 °C

Standard compliance:

  • EN 50178 for industrial applications such as:
    • Home appliances
    • Variable speed drives
    • UPS's
    • SMPS's
    • Air conditioners
  • European Directive EMC 2014/30/EU - CE marking

Remarks:

  • LH 25-NP is a multi-range model (8 - 12 - 25 A ranges)
  • Primary conductors already integrated into the transducers for an optimized coupling between primary and secondary
  • Primary conductor to be soldered on PCB
  • 100% fully compatible vs LEM LAH models
