Intelligent pump controller - model IVR 02 m - is an easy -to -use control and protective device for direct connection of single -phase deep pumps, surface pumps, submersible pumps, etc., from 0.37 kW to 1.5 kW (from 0.5 HP up to 2 HP) maintaining a constant, given water pressure by changing the speed of the pump engine. Model IVR 02 M has many operational modes by adapting to various electrical installations.
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.
- The long -term reliability 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 control the operation of two pumps supplying the system.
