The CurrentWatch EAC Series from
Eaton’s electrical business 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 – 5V
DC or 0 – 10V DC. This
sors is designed for application on
“linear” or sinuAvailable in split-core or solid-core
housings.
For typical applications of the CurrentWatch EAC Series, see listing to the
right.

AC Current Sensor with Analog Outputs and Power
Supply Options
Product 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, C-UL and CE Approved — Accepted worldwide
■
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
