ACS712 as current probe and AC voltage module as voltage sensor

[hussamaldean]

Hi all
I am thinking to use ACS712 hall effect current measurement as cheap current probe which will be connected in series with the load and AC voltage module for arduino 
 here is the picture of the module


I am planning to use those for power, PF and harmonic distortion on the load which will not draw more than 2A at max  (Note : I will use isolation transformer to power the load )   while the current sensor can handle up to 30Amps peaks and the voltage sensor up to 1000Vrms
what do you think about these module for such application?
I hope it is a good idea since I have those module and I used them before for wireless power meter project of mine
