Custom High Frequency Current Transformer


Accuracy ±1% or better, initial pulse response for all models, with a high impedance load such as 1 megOhm in parallel with 20 pF. A 50 Ohm termination will reduce the output to half. All models listed below come with a BNC connector except as noted and are to be used with a 50 Ohm coaxial cable. The current monitor case is conductive and not insulated. Adequate insulation must be provided on the conductor being monitored. To avoid electrical shock, do not mount or remove the current monitor from a live conductor.

  • Accuracy +1%, initial pulse response for all models, with a high impedance load such as 1 megOhm in parallel with 20 pF. A 50 Ohm termination will reduce the output to half.
  • Droop: For a flat top current pulse, the output voltage decays toward zero. Initially, the decay appears linear and the slope is referred to as the droop rate.
  • Usable Rise Time: If the 10 to 90% rise time is greater than the specified usable rise time, initial overshoot will be less than 10% of the pulse amplitude.
  • = Type N Connector
