Open Loop Hall Effect Current Sensor CYHCT-E4A
This Hall Effect current sensor
is based on open loop principle and can be used for
measurement of DC currents. The output of the transducer
reflects the real wave of the
current carrying conductor.

CONNECTION
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: 1. +15V/+12V Power Supply
|
|
2. -15V/-12V Power Supply |
|
3. +Output |
|
4. Ground |
|
 |
Notes:
1. Connect the terminals of power source, outputs respectively and
correctly, never make wrong connection.
2. Two potentiometers can be adjusted, only if necessary, by turning
slowly to the required accuracy with a small screwdriver.
3. The best accuracy can be achieved when the window is fully filled
with bus-bar (current carrying conductor).
4. 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.
