AC Current Probe Model JM830A
The Model JM830A 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 3600A
AC. The
“squared” jaw permits multiple conductor or bus bar positioning. The Model JM830A provides excellent True RMS capabilities and reliable signal reproduction.
The Model JM830A works as a tradi­tional current transformer providing current outputs (mA) over a broad range of transformation ratios. The Model JM830A is designed for use on DMMs, power and harmonic meters, recorders or instruments with AC current ranges.
Features
Nominal range: up to 2400AAC
(continuous cycle for the full temperature range)
• Transformation ratio: 3000:1
Output: 0.333mA/A
Designed for use on DMMs, power
and harmonic meters, recorders or
