Closed Loop Hall Current Sensor
CYHCS-D5-300A
This Hall Effect current sensor is based on closed loop compensating
principle and can be
used for measurement of DC and AC current, pulse currents etc. The
output of the
transducer reflects the real wave of the current carrying conductor.

Operating instructions
1. Connect the terminals of power source, outputs respectively and
correctly, never make
wrong connection for DC current.
2. Temperature of the primary conductor should not exceed 100 °C.
3. Dynamic performances (di/dt and the response time) are best with
a single bar
completely filling the primary hole.
4. In order to achieve the best magnetic coupling, the primary
windings have to be wound
over the top edge of the device.
