Aktuelle Wandler in der SMD-Serie Go-SME und GO-SMS-Technologie

GO – SME and GO – SMS current transducers

GO-SME and GO-SMS series are miniature SOIC packaged sensor for isolated current measurements integrating the conductor.

 

Przetworniki prądowe w technologii SMD serii GO-SME i GO-SMS

Features:

  • AC[&]DC current measurement for 10 and 20A (GO-SME and GO-SMS) or 30A (GO-SMS) nominal
  • SOIC8 (GO-SME) or SOIC16 (GO-SMS) packaging for SMD automatic assembly
  • Isolated measurement (2500V RMS isolation test voltage for GO-SME and 3000V RMS isolation test voltage for GO-SMS)
  • Low power consumption
  • High immunity to external interference
  • High insulation capability
  • Single power supply +5 V
  • Response time 2 μs
  • 5 years warranty
  • No magnetic hysteresis
  • Low electrical resistance (0.9mΩ - GO-SME and 0.75mΩ - GO-SMS)
  • Ratiometric voltage output with high sensitivity (up to 80mV/A)
  • DC – 300kHz
  • OCD (only GO-SMS)

Applications:

  • Small drives
  • HVAC
  • E-bike
  • Solar (GO-SMS)
