HLSR-PW Series Current Sensors

LEM USA's current sensors bring performance in a small package, allowing for more compact designs

Image of LEM USA's HLSR-PW Series Current Sensors The HLSR-PW series current transducers from LEM USA bring 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 0.5 V to 2.65 V) of the DSP (digital signal processor) or A/D converters commonly used in power electronics, allowing cancellation of the reference temperature drift.
