Product Description
A2 series rainproof three phase duplex water pump controller adopts the original imported microcomputer single chip technology,which has the advantage of powerful function and simple and convenient installation.The unique non-contact induction technology realizes the shutdown protection when the pump is dry run and short of water without installing a probe in deep wells.Make the pump truly realize full intelligent unmanned management.
Typical application scenarios:
-Agricultural irrigation/ pumping
-Pressure Booster Systems
-Waste water treatment
-Water Tanks/Wells
-Drainage System
-Cooling Towers
-Flood Control
-Fishing Boat

1)How to convert HP into KW ?
The conversion formula as :1HP=0.74KW
for example: 3PH=3x0.74KW/PH=2.22KW.
2)How to choose the power of your pump controller?
Normally we need choose bigger power to run the water pump or motors,.If the pump rated power is 4KW,Pump controller should choose 7.5KW.For Submersible pumps which used in the deep well,please check with us first .
3)Can I have the samples of your pump controller ?
Yes, we can send you the pump controller samples for your testing .
4)Can you provide OEM or ODM ?
Yes,we can make the ordes according to your detailed request.
5)what is your delivery time?
It takes 3-5 days for sample orders,and 15-20 days for orders
