Remote Current Indicator
The Remote Electrical Current Indicators provide an effec-
tive method for remote monitoring of electrical current. The
remote current sensing transformer is installed around the
current-carrying wire and is connected directly to the LED
panel indicator. When the current exceeds the turn-on point
of the sensing transformer, the LED illuminates to indicate the
presence of current. Two sizes of remote current sensing
transformers are available for use with either one of two
types of LED indicators. The panel indicators are available
with either red, green, blue, white, yellow or amber LEDs.
