Product Features
|
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. |
|
With soft start and soft stop, water pump’s service life will be extended. |
|
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 |
|
The interface is convenient to operate, no need of professionals to test or maintain. |
|
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. |
|
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. |
FAQ
Q: I am very interested in the frequency inverters and water pump controllers you produce. Can I apply for agency rights?
A: Thank you for your appreciation of our products. Our company has some assessment standards for the award criteria of agents. For specific details, you can contact our colleagues in charge of overseas sales.
Q: What is the pressure regulation range of your inverter? What capacity pressure tanks are normally equipped?
A:The frequency converters and variable frequency water pumps we produce have a starting pressure of 0.3bar and a pressure regulation range of 0.5-9bar. Generally, a 5L pressure tank is equipped during the using process. Of course, 8L or 12L pressure tanks can also be configured.
Q: How many inverters can be connected online at most?
A: Our inverters can connect 6 devices simultaneously
Q; Does your inverter have RS485 function?
A: Have mass-produced inverters for water pumps with RS485 function, and Modbus protocol can be provided during the cooperation process.
Q: The input voltage of the inverter is 220V, can the output voltage be 380V?
A: The input voltage and the output voltage must be the same. For example, if the input voltage is 220V, the output voltage is 220V; if the input voltage is 380V, and the output voltage is 380V.
Q: What are the wiring methods of the inverter?
A: 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.
Q: Where is your factory?
A: We currently have 2 production plants according to our product line. Welcome to visit our factory. After you arrive in Ningbo, we can pick you up at the airport or railway station.
Q: When can I get the prices?
A: We will reply within 24 hours after receiving your inquiry.
