AC Current Probe
Model SR651

The Model SR651 is designed for use
in industrial and utility environments.
The unique ergonomic design allows it
to easily clamp onto cables or small
bus bars. It is built to the highest safety
and performance standards including
the CE Mark and is UL approved.

Excellent transformation and low
phase shift, plus a broad frequency
response, permit accurate measure­ments of current for power and power
quality measurements. The high
quality magnetic cores and uniform
windings provide sensitivity for very
low level current measurements, as
well as measurements up to 1200A

AC.

The Model SR651 provides an
accurate voltage output of 1mV/A.
This voltage output enables
instruments without current ranges to
measure, display log currents through
an AC voltage range or measure very
low AC.

Features

• Measurement range of

100mA to 1200A

AC
