IVR 09 T (7.5 kW, 400 V, 18 A) Inverter

The intelligent pump controller, model IVR 09 T, is an easy-to-use control and safety device for direct connection of submersible pumps, surface pumps, submersible pumps, etc. maintaining a constant, set water pressure by changing the rotational speed of the pump motor. The IVR 09 T model has many operating modes by adapting to different electrical installations. IVR 09 series controllers can be used in pump groups of up to 6 pumps.

FEATURES

1. Energy efficiency: compared to the traditional method, the constant pressure water supply system with frequency converter saves energy by 30 - 60%.
   
2. Long-term reliability of associated pumps: average torque and shaft wear are reduced due to a decrease in average rotational speed, which ensures a longer pump life. 
3. The built-in SOFT-START and soft stop function of the device allows you to eliminate water hammer (the water hammer effect means a sudden increase in pressure accompanying a quick stop or start of liquid flow).
4. Comprehensive protection: the system has the most comprehensive protection technology for overcurrent, overvoltage, undervoltage, short circuit, blocked rotors, the ability to protect the pump against dry running without the need to install probes/sensors in the well.
5. Possibility to connect controllers into pump groups, up to 6 pumps. The group is managed from one controller, selected by the user as the main controller. The others adapt the work to the system requirements. Programming the set is very simple and does not require specialized knowledge.

APPLICATION

The IVR 09 T model will work wherever there is a need to maintain constant water pressure in the installation and to control and protect a pump or a set of several pumps.

IVR 09 T automatically manages switching on and off and adapts the engine speed to the installation requirements.
