HOYS Series Hall Effect Current Sensors

LEM high-performing current sensors ensure reliable and efficient protection in industrial applications

Image of LEM USA, Inc HOYS Series Hall Effect Current SensorsThe HOYS series from LEM are high-performance, contactless current sensors based on open-loop Hall effect technology, designed for accurate measurement of DC, AC, and pulsed currents ranging from 100 A to 560 ARMS nominal. Engineered for industrial applications, these sensors offer galvanic isolation and are built for easy mounting on busbars with large apertures. HOYS current sensors feature fast response times, low offset and gain drift, and include a dedicated overcurrent detection function preset at 2.93 times the nominal current (IPN), ensuring reliable and efficient protection in industrial applications.

  • Open-loop multi-range current sensing
  • Voltage output
  • Single supply: +5 V
  • Overcurrent detection: 2.93 x IPN (peak value)
  • Galvanic separation between primary and secondary circuit
  • Low power consumption
  • Buspar mounting: aperture 21.5 mm x 13 mm
 
  • Factory-calibrated
  • Mating JST connector: housing PAP-05V-S/contact SPHD-00T-P0.5
  • Low offset drift

  • Low-profile 2 mm pitch connector for 22 AWG to 28 AWG wire
Applications
  • AC variable-speed and servo motor drives
  • Static converters for DC motor drives
  • Battery-supplied applications
  • Uninterruptible power supplies
 
  • Switched-mode power supplies
  • Power supplies for welding applications
  • Combiner box
  • Solar inverter on the DC side of the inverter
