AEMC SR604 Data sheet

AC Current Probe Model SR604

The Model SR604 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 for
Canada and United States.

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
The Model SR604 works as a
traditional current transformer (with
a ratio of 1000:1) and provides current
outputs in mA/A for use on DMMs,
power and harmonic meters, data
loggers, recorders or instruments with
current ranges.
