D20 2MHz frequency bandwidth 200A AC/DC current probe

ac dc current probe

The Model D20 AC/DC current sensor is a portable 100A/200Arms current clamp with insulated BNC output cable that can accurately measure AC or DC current waveforms. The unit has proportional mV output for direct readings on oscilloscopes from DC to 1MHz at -3dB. The D20 is power by a rechargeable multimeter battery or from a 9 V power signal cable. It is the perfect tool for most of the oscilloscopes.



The D20 current sensor is a general purpose 200A AC/DC current probe designed for use with DMMs, oscilloscopes, power loggers, multimeters and energy meter calibration instruments that have a current input. It has a 1000:1 ratio and output of 10mV per amp measured in the jaw. The D20 AC/DC current sensor has an integral 2.5m lead terminated. The rounded jaw design on this current clamp makes it well-suited for power applications where high linearity 0.1% and low phase shift and wide frequency response up to 200kHz are important.
