The HOYL-S by LEM is an open loop Hall effect device designed for the electronic measurement of DC, AC and pulsed currents with galvanic separation between the primary and secondary circuits

  • The HOYL-S has primary ratings of 200 – 800A and can measure up to 2000A DC or AC
  • A single +5Vdc power supply is required to provide power
  • The HOYL-S Hall effect current transducer is 1% accurate
  • It outputs 2.5V at 0A on the primary, outputs 3.3 V at the rated current (positive) and 1.7V at the rated current (negative)
  • The HOYL-S can measure DC current and pulsed currents, as well AC frequencies up to 140 kHz (-3 dB)
  • It has a fast response (~3 µS) and low offset drift
  • These devices have been evaluated for over voltage category III and pollution degree 2 environments
  • Features
    • Open loop multi-range current transducer
    • Voltage output: Instantaneous 2.5 +/- 0.625 V
    • Single supply +5 V
    • Overcurrent detection 2.93 × IP N (peak value)
    • Galvanic separation between primary and secondary circuit
    • Low power consumption
    • For busbar mounting
    • Aperture: 40 × 13 mm
    • Factory calibrated
    • Mating JST connector
      • housing PAP-05V-S
      • contact SPHD-00xT-P0.5
    • Advantages
      • Low offset drift
      • Over-drivable Uref
      • Creepage / clearance > 10.5 mm
      • Fast response
      • Low profile 2 mm pitch connector for 22 to 28 AWG wire
    • Applications
