Closed Loop Hall Effect Current Sensor
CYHCT-E3
This Hall Effect current sensor is based on closed loop compensating
principle and can be
used for measurement of DC currents. The output of the transducer
reflects the real wave of
the current carrying conductor.

The current carrying cable must pass through the
window. The phase of output is the same
that of the current passing the window in the direction of the arrow
indicated on the case.
Wiring of Terminals:
+: +15V/+12V Power Supply
M: Output
-: -15V/-12V Power Supply
Notes:
-
Connect the terminals of power source, outputs respectively and
correctly, never
make a wrong connection.
-
Two potentiometers can be adjusted, only if necessary, by turning
slowly to the
required accuracy with a small screwdriver.
-
The best accuracy can be achieved when the window is fully filled
with bus-bar
(current carrying conductor).
-
The in-phase output can be obtained when the direction of current
of current carrying
conductor is the same as the direction of arrow marked on the
transducer case.
