Intelligent pump controller, model IVR-03 is an easy-to-use control and protective 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. Inverter IVR 03 uses SPWM technology (sinusoidal module of pulse width) and a high -performance spatial vector using V/F/VVVF control (variable speed, variable frequency). By analyzing the pressure in real time, the inverter adjusts the pump speed to the current system's demand. The variable rotational speed of the pump stabilizes the pressure, which significantly saves water and electricity consumption.
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.
- 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.
APPLICATION
Model IVR 03-030 T will work wherever there is a need to maintain constant water pressure in the installation and control and protection of the pump or set of two pumps.
