IVR 11-4T004A0 (3-4 kW, 400 V) Inverter with sensor

Intelligent pump controller, Model IVR 11 is an easy -to -use control and protective device for direct connection of three -phase pumps, surface pumps, submersible pumps, etc. with a power from 0.75 kW to 7.5 kW (from 1 HP to 10 HP) maintaining a fixed, provided water pressure, by changing the speed of the pump engine. IVR 11 is a drive with a frequency converter, specially designed for water pump performance management, which allows it to adapt to a wide range of conditions and requirements for water supply systems. The IVR 11 drive allows the pump to work more efficiently, safer and smarter, reduce energy consumption and extend the pump usability. The IVR 11 drive is made of high quality components and materials and uses the latest microprocessor technology.

The IVR 11 model has many operational modes by adapting to various electrical installations. Drivers from the IVR 11 series can be used in pump groups up to 5 pumps - a maximum of 1 superior device and 4 auxiliary devices.

The most important features

1. Increasing energy efficiency. Compared to the traditional method of supplying water, the system with a constant pressure with a frequency converter saves energy by 30%-60%.
2. Simple operation: All functions can be completed by pressing the button, there is no need to employ specialists for programming the device.
3. 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 and stop function allows you to eliminate a hydraulic impact. (The effect of a hydraulic impact is a sudden increase in pressure, accompanying a quick retention or starting liquid flow).
4. 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.
5. The ability to connect drivers into pump groups, up to 5 pumps. The group is controlled from one level - chosen by the user as the superior - controller, and the others adapt the work to the system's requirements.

APPLICATION

Model IVR 11 is useful in all cases when you need to maintain constant water pressure in the installation as well as control and protection of a single pump managing automatic switching on and off by various electrical installations.

Choose 1 and 2 for the main drive and 3 for auxiliary devices.

• Built -in PID regulator: Advanced PID regulator arithmetic to operate the control system in a closed loop.
• Draction speed control: automatic reduction of current and voltage during work,
• The parent drive connector: Extendable RS485 construction, one drive in the system can be superior and controls other auxiliary drives (maximum four) to work in communication mode. The main drive sends the PID controller feedback to auxiliary drives and monitors their state in real time. Auxiliary drive faults do not affect other drives.
• Protection against lack of water: If the drive detects that the pipe pressure is lower than the set water shortage pressure, the system automatically stops working. After a certain period of time, it starts automatically in certain cases. If the pressure returns to normal, the system works normally. Otherwise, the system stops automatically, which in the case of the inactivity of the pump, extends its usability to the maximum.
• High pressure alarm: when the pressure exceeds the set value, the system stops working automatically, which avoids damage to the pipes due to too high pressure.
• Automatic energy saving mode: automatically reduces the output voltage at low load to save energy.
• Password setting: 4-bit password can be set using non-zero numbers. After leaving the setting interface, the password will be valid in 1 minute.
• Blocking parameters: determine if the parameter is blocked in a state running or detained in case of incorrect operation. Operational conditions.
• Installation: Installation should be made in conditions without direct sunlight, dust, corrosive and flammable gases, oil fog, water vapor and moisture.
