Just back from Ace Ikano they have demo unit there. After the e2saver is ON can see the Current reading on the Amp meter drop from 1.5A to 0.7A.
I saw before a bridal house in ss2 also using with 3 Phase using 3 units of this product.
Quite impressive thou... but the salesman kinda "Arrogant".
From engineering point of view, it cannot drop at this kind of rate, as power factor correction is somehow like a few % up to teen number % improvement, unless the origin power is severely lag in the first place.
If you motor is 1HP (0.75KW) and running at its full capacity, your power consumption would be 750/230v = 3.26amp.
So if you want to consume 1.5amp to run at 1HP, there is no way unless you sacrifice the motor running speed only
Power = voltage x current (amp).
To have real and actual power saving, tell the salesman to install it in your house, then see the Amp drop how many, only then we can have actual figure to compare. Otherwise, any demo unit can be customised to show extra-ordinary good effect.
