Description

Current testing modules CTM series contains high-accuracy Hall sensors, can be used for measurement of DC, AC, pulses and currents of many different waveforms under isolated conditions together with co-axial cables and oscilloscope. It can also be flexibly used together with multi-meter to measure output voltage amplitude at the BNC terminals, which can be multiplied with a factor to get the corresponding current. The range of current measurement includes: 50 A, 100 A, 200 A, 300 A or to be customized higher.

Features

  • Super fast response time (<1 μs);
  • Strong anti-interference capability with modular design;
  • Strong adaptability, wide operating voltage range;
  • Flexible usage, can be used together with multi-meter for AC / DC measurement;

Standard

  • JB/T 7490:2007
