1, Hall sensor can measure any waveform of current and voltage, such as: DC, AC, pulse waveform, etc., and even the measurement of transient peak. The secondary current faithfully reflects the waveform of the primary current. The general transformer can not be compared with it, it is generally only suitable for measuring 50Hz sine waves.

2, the original side circuit and the sub-side circuit between the complete electrical insulation, insulation voltage is generally 2KV to 12KV, special requirements can reach 20KV to 50KV.

3, high accuracy: the accuracy in the working temperature zone is better than 1%, the accuracy is suitable for any waveform measurement. The general precision of the general transformer is 3% to 5% and is suitable for 50Hz sinusoidal waveform.

4, good linearity: better than 0.1%

5, good dynamic function: response time is less than 1μs tracking speed di/dt is higher than 50A/μs

6. This excellent dynamic function of Hall sensor module provides a key foundation for improving the function of modern control systems. Compared with the general transformer response time of 10-12ms, it can not meet the needs of the development of work control system.

7. Wide working frequency band: the accuracy is 1% in the 0-100kHz frequency scale. The accuracy is 0.5% in the 0-5kHz frequency scale.

8, measurement scale: Hall sensor module is a system product, current measurement up to 50KA, voltage measurement up to 6400V.

9, overload capacity: when the original current overload, the module reaches full, can actively protect, even if the overload current is 20 times the rated value, the module will not be damaged.

10, the module size is small, light weight, easy to install, it will not bring any loss in the system.

11, the "capacitance" between the primary and secondary modules is very weak, in many applications, the various effects of the common mode voltage can usually be neglected, when the high voltage changes of several thousand volts /μs are reached, the module has its own shielding effect.

12, the high sensitivity of the module, so that it can distinguish the weak signal on the "high weight", for example: in the DC weight of several hundred amps to distinguish a few milliamps of AC weight.

13, high reliability: loss of power: λ=0.43╳10-6/ hour

14, strong resistance to external magnetic field interference: at 5-10cm from the module, there is a magnetic field interference caused by a current twice the working current (2Ip), the error is less than 0.5%, which is sufficient for most applications, anti-external magnetic field interference, but appropriate measures should be taken for strong magnetic field interference.
