Application of Acrel Hall Sensor in Chile

Abstract:Thisarticle introduces the application of the Hall Sensor used inchile. Hallcurrent sensors are mainly used to isolate and convert AC, DC, pulse and othercomplex signals. After signal control of current signals are convertedaccording to the Hall Effect Theory, they can be directly acquired by AD, DSP,PLC, secondary instruments and other devices. Hall current sensors are widelyapplicable for acquisition and feedback in the current monitoring, batteryapplication, inverter, solar power management, direct current cabinet, DC motordrive, electroplating, welding, frequency converter, UPS servo control systems.They feature the quick response, wide range of measurement, high precision,strong overload capacity, good linearity and excellent anti-interferenceperformance.

1.Project overview:

The companythat do lithium batteries need to use DC Hall sensors to transmit DC current tothe 4-20mA analog signal output. After confirming the input and output and workingpower, the customer chose AHKC-EKA and AHKC-EKAA.

2.Compared withthe traditional DC current measurement method generally adopted by shunt ortransformer, the open-type Hall sensor has the following advantages:

1) High insulation strength of primary side andsecondary side, up to AC 12KV isolation;

2) No insertion loss;

3) Good dynamic performance: the response time is lessthan 20uS and the tracking speed Di /dt is higher than 20A/ uS

4) There is no need to disassemble the original sidecable or bus during installation. It is especially suitable for the transformationand construction of equipment that is not allowed to lose power.

3.Product Selection

4.Application

Hall currentsensor is mainly used in factory transformation of DC power distributionsystem, photovoltaic, UPS, motor system, etc. It can convert the primary DCcurrent signal in the system into a standard DC ± 5V or 4-20mA output, which plays a role in monitoring andelectrical isolation , It can be used with multi-loop monitoring instruments orother electrical measuring instruments.

5 .Conclusion

Open-end Hallcurrent sensor plays an important role in the application of DC system becauseof its simple structure, convenient installation, reliable operation .
