EAC Series CurrentWatch Current Sensors
Product Description
The CurrentWatch EAC
Series from Eaton’s Electrical
Sector combines a current
transformer and signal
conditioner into a single
package. The EAC Series has
jumper-selected current input
ranges and industry standard
outputs: 4–20 mA, 0–5 Vdc or
0–10 Vdc. This
family of
sensors is designed for
application on “linear” or
sinu-
soidal AC loads.
Available in split-core or solid-
core housings.
For typical applications of the
Current
Watch EAC Series,
see listing on this page.
Application Description
Typical Applications
●
Automation
Equipment—Analog
current reading for remote
monitoring and software
alarms
●
Data Loggers—Self-
powered sensor helps
conserve data logger
batteries
●
Panel Meters—Simple
connection displays power
consumption

Example Application—
Preventative Maintenance of a Critical Lighting System
Features
●
Highly Accurate—Factory
matched and calibrated
single-piece sensor is
more accurate than
traditional two-piece, field-
installed solutions
●
Average Responding—
“Average Responding”
algorithm gives an RMS
output on pure sine waves,
perfect for constant speed
(linear) loads
●
Jumper Selectable
Ranges—The ability to
change input ranges
reduces inventory and
eliminates zero and span
●
Isolation—Output is
magnetically isolated from
the input for safety and
elimination of insertion loss
(voltage drop)
●
UL, cUL and CE
Approved—Accepted
