The HF series shunts provide an accurate current sensing solution for many wideband power  measurement applications up to 500Arms, the shunts are supplied with a 2m safety BNC lead.  Utilising an innovative design unique to N4L that exhibits exceptionally low parasitic inductance, each shunt will  maintain its specified resistance over a frequency range from DC to 1MHz without exhibiting the phase shift that  is normally associated with high current resistive shunts.  While the HF series was primarily designed for use with the PPA series power analyzers from N4L that provide  exceptional wideband accuracy, dynamic range and common mode rejection, the HF series can be used as a  precise current sensing device for other equipment.
