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

instruments with AC current ranges

Applications

• Field testing

• Electrical utility

• HVAC

• Industrial maintenance

• Laboratory

• Plant maintenance
