Open Loop Hall effect LEM current transducers HO & HLSR with digital output

Open Loop Hall effect LEM current transducers HO & HLSR with digital output

Main characteristics:

  • Nominal AC & DC current measurement of 16, 32, 40, 50, 80, 100, 120, 150, 200, 250 ARMS
  • 4 different mechanical designs (PCB or panel mounting)
  • Integrating a sigma delta modulator
  • 1-bit serial bitstream output
  • Up to 12 bits resolution
  • 20 kHz Bandwidth
  • 10 MHz clock frequency
  • Single-bit output 2 wires CMOS or RS422 Manchester or LVDS Manchester which minimises the connections required.
  • or 4 wires mode according to the LVDS or RS 422 standards.

Features:

  • Power supply + 5 V
  • Operating temperature range from -40 to +105°C
  • HLSR -PW have only the clock and the data in single-ended signals with CMOS levels. Alternatively, the output may be Manchester coded on 2 pins, meeting the RS422 standard
  • HO-NPW, HO-PW and HO-SW models can have the single-ended and Manchester modes as with the HLSR-PW models but they add 2 extra pins so both the clock and data may be differential signals that meet the RS422 and LVDS standards
  • HO family have additionally an Over-Current Detect
