AC Current Probe Model JM875

The Model JM875 is a high performance AC current probe for higher currents. Excellent transformation and low phase shift, plus a broad frequency response, permit accurate measurements of current and power. The high quality magnetic cores and uniform windings provide for accurate measurements up to 30AAC/300AAC/3000AAC. The squared jaw permits multiple conductor or bus bar positioning.

The Model JM875 provides excellent True RMS capabilities and reliable signal reproduction. It also provides an accurate voltage output proportional to the measured current (1mV/A,10mV/A or 100mV/A). This voltage output enables instruments without current ranges to display or log currents on an AC voltage range.
