  • Closed loop technology combined with ASIC
  • Operating temperature range: -40°C to +85°C
  • Voltage output (LTS & LTSR models) / Current output ( LTSP model)
  • LTS: Bandwidth DC to 200 KHz
  • LTSR: Reference access / LTSP: reference readout access only (2.5 V)

Standard compliance:

  • EN 50178 for industrial applications such as:
    • Home appliances
    • Variable speed drives
    • UPS
    • SMPS
    • Forklift trucks
    • Air-conditioners
    • Current monitoring
    • Welding applications
  • EN 60950
  • Using UL94-VO recognized materials
  • European Directive EMC 89 / 336 / EEC: CE marking
  • Low voltage directive 72 / 23 / EEC


  • Each model is multi-range according to primary connection configuration
  • Bipolar currents measurements when single supplied 0/+5V
  • This transducer can directly be connected to the 5V input of mcontrollers and instrumentation cards
  • LTSR brings an additional pin, at the output for more flexibility in applications. This pin provides access to the internal voltage reference of the ASIC which can then be fed to the reference of an A/D converter (Analog Digital) This extra pin can also receive the internal reference (from 1.9 to 2.7 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift
  • LTSP provides the internal reference (2.5 V) on the additional pin when it is not possible to receive it from external source.
