HTFS

Measures from 200A up to 800ARMS for PCB for low voltage applications


Main characteristics:

  • 6 models with an unique size
  • High current measurement from 200 up to 800ARMS with a PCB mounting
  • 22 mm diameter aperture for the primary conductor
  • Operating temperature range: -40 to +105°C
  • 5 years warranty

Features:

  • DC, AC pulse currents' measurements with galvanic isolation
  • Single supply 0, +5 Volt
  • Isolation test voltage: 2,5 KVRMS / 50Hz / 1min
  • Voltage output
  • Ratiometric offset
  • Fixed gain
  • Reference access
  • Open loop technology combined with ASIC

Standard compliance:

  • EN50178 for industrial applications such as:
    • Low voltage applications
    • Forklift trucks
    • Battery supplied applications
    • Golf cars
    • Wheel chairs
    • Telecom applications
  • European Directive EMC 89 / 336 / EEC: CE Marking
  • Low voltage directive 72/23/EEC
  • Safety IEC 61010-1

Remarks:

HTFS 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 2 to 2.8 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift. When the standard models are mechanically fixed to the PCB, the SP2 models are fixed to the PCB thanks to 4 additional pins to be soldered. In both cases, secondary connections are pins to be PCB soldered.
