Advantages of Hall Effect Current Sensor
	Current Transformer	Hall Effect Current Sensor
Functionality	Generally, only the AC current is enlarged or reduced according to a certain ratio. The functions are relatively single.	DC and AC can be fully compatible. It can measure AC and DC currents and output industry standard signals.
Safety	If the measured current suddenly increases, the induced current will often increase sharply, which will cause the collected instrument to burn out due to large current.	Generally resistant to 120% FS, even if there is a sudden large current, because the input and output are isolated from each other, the safety of the instrument can still be guaranteed.
