Product Features:
- This inverter is used especially for water pump. It adopts the industry leading technique SPWM and pressure transmission technique, detects actual pipeline pressure change and controls the rotation speed of the pump. After the inverter is connected to the float switch, when the float switch is in the high position, the inverter stops working; when the float is in the low position, the inverter starts working.
- The operation of this device is very easy, all functions can be finished by parameters setting, without the need for professional debugging.
- The inverter is highly efficient and can save up to 20%~60% of water and electricity compared to traditional water supply systems.
- Soft starting and stopping, constant water pressure, prolong the service life of the pipe network and make the water usage comfortable and enjoyable.
- Wide voltage range allows for stable operation even in areas with significant voltage fluctuations.
- The installation is very easy with direct screw thread, and different types of water pumps can be used, thus reducing the extra cost.
- LED display makes it convenient and fast to check and set actual pressure values.
Application
- Tap water booster system
- Household and residential water supply system
- Swimming pool water supply system
- Commercial water supply system
- Factory dormitory water supply system
- Industrial water circulation system
- Cooling water systems
- Cold water circulation systems
