1. Project Overview
Saudi Arabia AFAQY company mainly do the installation project of communication equipment. The Hall current sensor they purchased is mainly installed in the UPS power cabinet to monitor the current situation and protect the back-end equipment.
2. AHKC Series Hall current sensor
Hall sensor is suitable for the isolation and conversion of complex signals such as AC, DC and pulse. Through the Hall effect principle, the converted signal can be directly collected and accepted by various acquisition devices such as ad, DSP, PLC and secondary instrument. It has the advantages of small volume, long service life, convenient installation, fast response time, wide current measurement range, high precision, strong overload capacity and good linearity, It has the advantages of strong anti-interference ability.

4. Summmary
In the UPS power system, the closed-loop Hall current sensor is used to measure the output current, and the ups controller carries out feedback control according to the current to ensure the normal operation of the inverter. Because of its fast response speed, it is especially suitable for uninterruptible power supply in computer.
With the widespread application of electronic medical equipment in hospitals, the threat of leakage current to patients is becoming greater and greater, especially in places where life is critical. The patients are directly exposed to various electrodes a
