Intelligent pump controller, model IVR 09 T is an easy -to -use control and protection device for direct connection of deep -sea pumps, surface pumps, submersible pumps, etc. maintaining a constant, provided water pressure by changing the speed of the pump engine. Model IVR 09 T has many operational modes by adapting to various electrical installations. Drivers from the IVR 09 series can be used in pump groups up to 6 pumps.
CHARACTERISTICS
- Energy efficiency: Compared to a traditional method, a water supply system with a constant pressure with a frequency converter saves energy by 30 - 60 %.
- Simple operation: All functions can be completed by pressing the button, there is no need to employ specialists for programming.
- Reliability for many years of cooperating pumps: average torque and abrasion on the shaft decreases due to the decrease in average speed, which ensures longer pump life.
- The built-in Soft-Start function and mild stopping of the device allows you to eliminate a hydraulic impact (the effect of a hydraulic impact means a sudden increase in pressure, accompanying a rapid stop or starting liquid flow).
- Comprehensive protection: The system has the most versatile technology of hypertension, overvoltage, undercoat, short -circuit, blocking the rotors, the ability to protect the pump against dry -one without the need to install probes/sensors in the well.
- Possibility to connect drivers into pump groups, up to 6 pumps. The group management takes place from one controller, chosen by the user as the main one. Others adapt the work to the system's requirements. Programming the set is very simple and does not require specialist knowledge.
APPLICATION
Model IVR 09 T will work wherever there is a need to maintain a constant water pressure in the installation and control and protection of the pump or set of several pumps.
IVR 09 T automatically manages the switching and off and adapts the engine speed to the installation requirements.
