Product Description And Application

WBI022F21 product adopts the principle of electromagnetic induction and hall effect to measure the AC and DC current of the power grid in real time. Using mean value conversion technology and magnetic compensation technology to reduce the temperature drift, it is converted to standard DC voltage (Uz) output, and the characteristics of good temperature stability, AC and DC current universal, strong overload capacity and high isolation.

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.

This product adopts DIN mount rail structure, convenient installation and disassembly. It is suitable for real-time measurement of power system, post and telecommunications system, railway monitoring system and so on.

Operating instructions

1. Connect the terminals of power source, output 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 the 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.
