Products Feature
|
This frequency drive converter is used only for water pump, with SPWM and pressure sensing technique, it collects real time pressure change of the pipeline and regulates the revolving speed of the pump. |
|
The interface is convenient to operate, no need of professionals to test or maintain. |
|
Compared with the old water supply methods, the frequency drive constant pressure water supply system saves up to 20%~60% energy with its high efficiency. |
|
The life quality will be improved and is more comfortable thanks to this constant pressure water supply system |
|
With soft start and soft stop, water pump’s service life will be extended. |
|
It can adapt to a wide range voltage, especially in places with large voltage fluctuation. |
|
All-round protection for the water pump motor can avoid unnecessary property damage. |
|
Simple installation, applied to varieties of pumps, greatly reduce the cost. |
|
LED intuitive display makes it fast and easy to check and set real-time pressure values. |

FAQ
What are the wiring methods of the inverter?
There are two wiring methods: 220V water pump with delta connection; 380V water pump with Y connection. If you have any questions during the usage, you can consult us at any time.
How many inverters can be connected online at most?
Our inverters can connect 6 devices simultaneously
What are the differences between the inverter produced by your factory and other inverters?
We produce frequency inverters especially for water pump, they are of better performance, better stability and simpler operation. In fact, once the frequency inverter is installed and used, or the product is disassembled, the quality difference will be known.
Does your inverter or water pump controller have EMC certification?
Yes, when we make TUV or CE certification, EMC certification has been included.
Can we customize mold for the frequency inverters for ourselves? How much does it cost?
We have a professional technical team, we can help you design product, the mold costs are borne by you, if your cumulative purchase quantity of frequency inverters reaches a certain standard, the previous mold costs can be refunded. For specific details, you can contact our colleagues.
Do you have built-in sensor and five-way inverters?
Yes, we produce inverters with built-in sensors and five-way? What’s the power and quantity do you need?
Can the frequency inverter you produce be used for deep well pumps? What are the requirements?
The frequency inverters we produce can be used for deep well pumps, and the length of the power cable cannot exceed 20 meters. The power of the frequency inverter should be larger than that of the deep well pump.
How can I place an order?
You can contact any of our foreign trade staff, in order to communicate more smoothly,please provide detailed contact information, you can use Skype, WeChat or WhatsApp or other instant methods to contact us.
