 Differential Probe
 


NDP1000 Series high voltage isolating probe applies differential input mode with outstanding isolation and safety performance on 2 inputs end. It is used at the location need to measure high voltage or isolate from ground usually.

  1. The 4M isolated input can eliminate the traditional isolating transformer in floating test, or completely eliminate the safety risk caused by improper instrument floating.
  2. The 25Hz~100MHz bandwidth can be easily used on power noise and harmonic analysis.
  3. T wo attenuation ranges 1/50 and 1/500 to be selected. The Maximum measurable differential voltage are 130V (DC + peak AC) and 1300V (DC + peak AC) accordingly.
  4. Alarm function for over range, in a red LED
  5. Small size and robust.
  6. It has very high stab ility, reliability and accuracy based on Integrated Circuit and SMT technique.
